The market town of Helmsley in the picturesque Ryedale district of North Yorkshire, England, is the location of the new International Centre for Birds of Prey (ICBP) which opened to the public in March 2013. Spread over eleven acres with historic Duncombe Park as a backdrop, the visitor attraction features more than a hundred birds housed in some forty aviaries, and is set to become one of the top tourist attractions in the district. In addition to being a visitor attraction, the ICBP runs a program of breeding endangered birds, most notably Steller’s sea eagles, which are among the world’s largest birds and listed as ‘vulnerable’ by the IUCN.

The ICBP has three flying demonstrations per day where visitors can witness the exceptional abilities of a variety of birds of prey. As each flying demonstration features different birds, with commentary offering fascinating facts about the performers, visitors may want to spend the entire day at the centre and watch all three demonstrations. In the event of inclement weather, the centre will move the demonstration to a sheltered wooded area or indoors, so visitors are assured of seeing the birds in action.

Visitors may want to start their tour of the centre along the Hawk Walk, where they will be able to approach within a few feet of the trained birds which includes hawks, falcons, eagles and buzzards. The main aviary area features a series of enclosures which have been carefully designed with the comfort of the feathered residents in mind. The three solid walls of each aviary provide the birds with a sense of security, which makes them more content and enhances their breeding abilities. The success of the aviary design is evident in the fact that the ICBP has successfully bred 65 species of birds of prey.

Overlooking the parkland in front of Duncombe Park’s main house, the Flying Ground has seating for demonstration spectators, as well as picnic tables and acres of well-tended lawn to relax on. The east and north of the area are sheltered by ancient oak, chestnut, ash and lime trees with the west open to the prevailing wind, providing perfect conditions for the birds to perform in.

Other facilities include the Fountain Tea Room, a shop and a play area. A visit to the International Centre for Birds of Prey is sure to be memorable. Don’t forget to take your camera!

Birdsong Apps Pose Threat to Breeding

$

Bird watching as a hobby has been traced back to the late-18th century as portrayed in the works of English naturalists and ornithologists Gilbert White, Thomas Bewick and George Montagu. During the Victorian Era, the study of birds became fashionable, but not necessarily in their natural habitats, as collectors obtained specimens of eggs and preserved dead birds sourced from around the world. In the late 19th century the Audubon Society in the United States and the Royal Society for the Protection of Birds in Britain were founded to protect birds from these collectors and from the increasingly popular feather trade. In 1901 a book published by British ornithologist and writer Edmund Selous, entitled simply Bird Watching, is thought to have been the origin of the term describing the practice of observing birds in their natural habitat – a pastime which requires plenty of patience.

In today’s society which is increasing becoming accustomed to instant gratification, patience may sometimes be seen as a hindrance rather than a virtue, and this may be the case among birding enthusiasts who are using mobile phone apps to mimic birdsong in an effort to attract birds. Wardens on England’s Brownsea Island have recently reported instances where visitors have used these mobile apps to mimic the unique call of the Nightjar, apparently so they could get a clearer photograph. What these visitors may not realize is that they are breaking a law (the Wildlife and Countryside Act of 1981) which was put into place to protect nesting birds from being intentionally disturbed. Designated as a Special Protection Area (SPA), Brownsea Island is home to a host of bird species, including the Nightjar which, thanks to conservation efforts, has experienced an increase in numbers in recent years.

When a recorded birdsong is played repeatedly it is likely to divert the bird from essential duties, such as feeding its young. It may also prompt a bird to interrupt the mating process to chase off what it perceives to be a rival in order to protect its territory.

Giving birders the benefit of the doubt that they may be unaware of the negative impact their birdsong apps are having, the Dorset Wildlife Trust is launching an online campaign to warn people of the harm they may inadvertently be causing. To reinforce the message, signs will be erected on each of the 42 reserves overseen by the Trust requesting that birdsong apps not be used in the reserves.

Administered by the United Nations Environment Program (UNEP) and developed in line with the Convention on Migratory Species (CMS), the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) is a program devoted to the conservation of migratory waterbirds and their habitats in Africa, the Middle East, Europe, Central Asia, the Canadian Archipelago and Greenland. This calls for the cooperation of governmental authorities in these regions, as well as the wider conservation community, to develop conservation principles that can be applied successfully to the management of migratory waterbirds along all their migratory routes.

The 255 AEWA-monitored species cross international borders during their annual migration and need suitable habitats as stop-over and breeding sites. Cooperation between countries along their routes is essential to ensure the survival of many of these species, which include grebes, divers, pelicans, herons, cormorants, storks, ibises, spoonbills, rails, cranes, gulls terns, auks, frigate birds and more.

As of June 1, 2013, seventy-one countries and the European Union are involved in the AEWA program, cooperating with one another in the interest of the birds. Representatives from these member countries meet every two to three years to review progress made and plan the way ahead. The first meeting was held in November 1999 in Cape Town, South Africa, with subsequent meetings being held in September 2002 in Bonn, Germany; in October 2005 in Dakar, Senegal; September 2008 in Antananarivo, Madagascar; and the most recent being held in May 2012 in La Rochelle, France.

Countries that have joined AEWA are legally bound to carry out core activities as outlined in the organizations Action Plan. The current action plan is valid until 2015 and includes legal measures that protect the habitat, eggs and birds of the identified migratory species, with certain exceptions if the bird population is deemed sustainable or if it poses a danger to crops, water and fisheries. The Action Plan also covers strategies for conserving specific species, emergency measures for species deemed in danger, and methods of re-establishing populations in their traditional range. Habitat conservation is covered in detail, as is the establishment and control of eco-tourism, as well as the education of personnel responsible for implementation of the Action Plan and members of the public.

Birding enthusiasts, who gather to greet the masses of migratory birds that have successfully completed their annual, often treacherous journey, can do so in the knowledge that organizations such as the AEWA are playing a vital role in the success of this marvel of nature.

Known as the “city that never sleeps” and “The Big Apple”, New York City is a vibrant bustling metropolis that has more than a few surprises for visitors – and for native New Yorkers – who choose to explore its natural resources. The New York Water Taxi service offers visitors the opportunity to see the city from the harbor and its waterways. Working with the New York City Audubon Society, in the summer months the water taxi service offers a NYC Audubon Summer EcoCruise to highlight the amazing diversity and abundance of birdlife resident on the small islands in New York Harbor.

Lasting around 90 minutes, the cruise makes its way past world-renowned monuments, under iconic city bridges and along the shoreline of islands where visitors can view some of the more than 3,000 herons that have migrated from the south, along with hundreds of cormorants, egrets, ibis and other birds. Ever mindful of the impact humans have on the habitats of birds, the fleet of vessels used by the water taxi service are fitted with low-emission engines and mufflers, while the hulls are designed to cut through the water with as little disturbance as possible. While on the tour, visitors will learn about the ecology of the harbor and the important role its islands play in the conservation of various bird species.

With more than 10,000 members, New York City Audubon has been protecting wildlife habitats and its residents in all five boroughs for more than thirty years, with the goal of improving and conserving the environment for future generations. Wild birds from more than 350 species either live or pass through the city each year – that is almost a third of all species recorded in North America. They depend on the lush, vegetated areas in Jamaica Bay, the islands of New York Harbor and Central Park for their survival. The society collects data relating to birds across New York City, using the information to monitor bird and wildlife populations, and acts as an advocate for wildlife at government policy-making level.

Education programs formulated by the New York City Audubon inform the public, both young and old, about being responsible environmental stewards. The society welcomes new volunteers to work towards the goal of protecting wild birds and natural habitats in New York City, thereby improving the quality of life for all.

Snake Skin as Protection Against Predators

$

Birds use all sorts of materials to build and pad their nests with, and are very good in general at adapting whatever is at hand to suit their needs. Some birds even use the shed skins of snakes in their nest building, raising the question as to whether the snake skin is merely a handy and comfortable material to line a nest with, or whether it is actually intended to scare predators off. A study carried out by Arkansas State University ornithologists concluded that some bird species clearly use the snake skin to deter predators by incorporating it into their nests in some way, or by prominently displaying a snake skin near the nest, or both.

The Tufted Titmouse (Baeolophus bicolor) and Blue Grosbeak (Passerina caerulea) are among the bird species that include pieces of snake skin in their nests, while Great Crested Flycatchers (Myiarchus crinitus) are known to display a snake skin outside their nesting cavity, as well as using an entire coiled snake skin in the nest. These will remain there throughout the incubation and fledgling stage of breeding. The study noted that the main predators of the eggs of Great Crested Flycatchers are rat snakes and flying squirrels – the latter being fond of bird’s eggs and the former preying on both birds and their eggs, as well as on flying squirrels. It was also noted that flying squirrels and Great Crested Flycatchers have a very similar geographical spread, and as all three species favor cavities as habitats, it is likely they will encounter one another. As the flying squirrel does its best to avoid the rat snake, it has been suggested that the shed skin of the snake acts as a deterrent to the squirrel.

A test carried out by the researchers confirmed that to be so. Using 60 nest boxes in which quail eggs were placed, researchers added snake skins into 40 of the boxes, with 20 boxes having no snake skin in them. All of the 40 boxes with snake skins were left untouched, while up to 20 percent of the nests without snake skins were raided by flying squirrels – evidence that some birds use snake skins specifically to ward off predators, and it appears to work.

Spectacular Courtship Ritual of Peafowl

$
0
0

Best known for the spectacular courtship display put on by the males of the species, peafowl originate in Asia and belong to the genus Pavo of the Phasianidae (pheasant) family. While the term “peacock” is often used to describe the entire species, irrespective of sex, “peacock” is the correct term for the male in the species, with the female being referred to as a “peahen” and their offspring are known as “pea chicks”. The name for a group of peafowl – pride or ostentation – is very descriptive and this colorful bird has long been associated with high social standing and royalty, particularly in Asian cultures. It also features in Hindu mythology as the mount of the god of war, Karthikeya.

The species of peafowl are the Indian Peafowl (Pavo cristatus), the Green Peafowl (Pavo muticus) and Congo Peafowl (Afropavo congensis). The Indian Peafowl is found in South Asia and is the national bird of India. The male of the species has a brilliantly blue colored body and head, which is topped by a fan-like crest of feathers. Its most prominent feature is its long train of upper-tail covert feathers covered in colorful, iridescent spots resembling eyes. During courtship, this breathtakingly beautiful tail is spread out into a fan and quivered by the male in an attempt to attract a mate. The female of the species has a duller brown plumage with its neck being a greenish color. Although they can fly and often roost in tall trees, Indian Peafowl are usually found on the ground, where they forage for berries, grains and other plant material, with lizards, snakes and small rodents also being on the menu.

While Indian Peafowl are considered to be of “Least Concern” by the IUCN, the Green Peafowl is listed as “Endangered”. Found in the tropical and subtropical forests of Southeast Asia, the Green Peafowl is a target of predators such as Leopards, Tigers, Jungle Cats and humans. Hunting and a loss of habitat has resulted in numbers of these beautiful birds dwindling to the extent that they are now considered to be endangered. The males and females of Green Peacocks are relatively similar in appearance, with the male’s upper tail coverts being longer than the female during breeding season. After breeding season the male molts, resulting in the appearance of the two sexes being even more similar.

Found in the Congo Basin, the Congo Peacock looks like a cross between a peafowl and a guineafowl, with the male’s feathers being a deep blue, tinged with green and violet, while the female is brown with shiny green feathers over its back. Due to habitat loss and hunting, the Congo Peacock has the IUCN status of “Vulnerable”.

Southeastern American Kestrel in Louisiana

The American Kestrel (Falco sparverius) is the smallest member of the family Falconidae in North America. The American Kestrel can be identified by two distinct black streaks on each side of the head that contrast with the white throat and cheeks, and by a blue-gray patch encircling a rufous-colored spot on the top of the head. The males have a prominent rufous coloration on the back and tail. The Southeastern American Kestrel (F.s. paulus), which is one of two subspecies that occurs in the United States, is a local resident of Louisiana. It is approximately the size of a robin, and the female is larger than the male. The Southeastern American Kestrel (SAK) is often seen during the winter months in Louisiana perched on telephone lines located along fields and pastures.

The resident SAK is often confused during the winter with the migratory subspecies F.s. sparverius, although the resident species is smaller. The mean body mass of the SAK is approximately 22 percent lower in males and 26 percent lower in females, as compared to the migratory subspecies. It is very difficult to distinguish the two subspecies in the field. F.s. sparverius may look chunkier, but it takes someone who has spent long hours in the field watching kestrels to determine the difference between the two subspecies.

SAKs form strong pair bonds that tend to remain permanent. Displaying high site fidelity, pairs often remain on or near their nesting territories. SAK territories can range in size from 300 to 700 acres. In Louisiana, the SAK prefers open, park-like pine forest and open areas with scattered mature trees, which are needed for perch and nest sites. It is important that forest stands do not have a dense understory. The SAK prefers the same type of habitat preferred by the endangered Red-cockaded Woodpecker (RCW).

The SAK begins breeding courtship in late winter. The courtship includes aerial displays in which the male performs dives and a flutter-glide to advertise to the female. The SAK nests in cavities located in snags or living trees, usually excavated by woodpeckers. The Pileated Woodpecker often plays on important role in creating cavities suitable for nesting SAKs by enlarging the cavities of smaller woodpecker species. The SAK will also use nest boxes, when they are placed in suitable habitat. On Fort Polk, we usually find our first eggs in early April, and a full clutch usually consists of four to five eggs. The incubation period lasts 29 to 30 days. The young will fledge around the age of 30 days. The adults and young will forage together until dispersal, which occurs in the fall.

The SAK hunts from a perch, on the wing, and hovering. It is a generalized predator, feedings on rodents, insects, reptiles, amphibians, and small birds. The favorite food items on Fort Polk are lizards, including anoles, fence lizards, and skinks.

The U.S. Fish and Wildlife Service formerly considered the SAK a candidate subspecies for listing as threatened or endangered. It is no longer being considered a candidate for listing, but is considered a species of concern. The SAK is listed as threatened in Florida by the state’s game and fish commission. The SAK is a nonmigratory resident of the gulf coast states, now very rare over much of its former range. Current range includes east Texas, Florida, Louisiana, and the southern portions of the states of Mississippi, Alabama, South Carolina, and Georgia. The ranges of the two subspecies overlap during the winter.

Habitat loss is the main factor in the population decline of SAK in parts of its range. Industrial forest lands provide open areas important for the SAK, but they do not provide mature trees for nests sites. When the timber matures, the timber stand is usually too dense to be suitable for the SAK. Lack of prescribed fire is also detrimental to the SAK, because it prefers open, park-like forest stands kept open by regular prescribed burning. Prescribed burning and placing nest boxes in suitable habitat are the quick and feasible ways to improve SAK habitat.

Southeastern Kestrel Management on Fort Polk

$

In 1992, Fort Polk banded its first juvenile kestrels, which were from a nest located in an enlarged RCW cavity. The kestrel nest tree was within 100 feet of an RCW nest tree, which indicates that RCWs and SAKs prefer the same type of nesting habitat. Both the RCW and kestrel had successful nests and fledged chicks.

The SAK often hunts over large openings in the forest. Fort Polk has a large number of openings in the forest, called firing ranges that are utilized by the SAK for hunting. Our most successful nest boxes are located on the edge or near firing ranges. Another favorite habitat on Fort Polk is Longleaf pine seedtree stands that have approximately 20 mature pine trees per acre. On Fort Polk, we thin our pine stands down to a basal area of 60, sometimes lower, and we have a three-year rotational prescribed fire program. Not only does this habitat management benefit the SAK and RCW, it also benefits other species of concern including Bachman’s and Henslow’s Sparrows, and the rare Louisiana Pine Snake.

Since 1993, we have placed 20-25 SAK nest boxes on Fort Polk. The boxes are placed 20 feet above the ground on pine trees. It is very important that a snag or telephone lines are located near the nest boxes; the SAK uses them for perching and hunting. Our nest boxes usually have 5-6 successful nests a year, producing 3-4 young each. In addition to our nest boxes, we usually find 3-6 nests located in natural cavities each year. Nearly all the nests are found in enlarged RCW cavities located in living or dead cavity trees. All chicks are banded with a U.S. Fish and Wildlife aluminum band and a combination of color bands. There is a lot of competition for the nest boxes from other bird species and squirrels. We usually have more Eastern Screech Owl nests than SAK nests. We have also found Great-crested Flycatchers, Tufted Titmice, and Eastern Bluebirds nesting in our boxes. If we find other bird species using the boxes, we leave them alone, but Fox Squirrels and Southern Flying Squirrels are removed. Flying squirrels are a big problem. It is not uncommon to find 4-8 flying squirrels occupying a nest box. The number one nest predator on nesting SAKs is the Texas Rat Snake, a great tree climber. We have found adults, young, and eggs consumed by the rat snake. To limit predation, we place aluminum sheeting (4 ft. wide) at the base of each nest box tree. The slick aluminum prevents the snake from climbing the trees and reaching the nest boxes.

With proper management, SAK populations should remain stable and possibly increase in the future on federal lands, including Fort Polk and National Forest Service lands. It is critical that regular prescribed fires and timber thinning continue into the future. Not only is this necessary for maintaining healthy populations of SAK, but for other rare species that share its habitat.

Attending a Local Bird Fair

$

Have you previously attended a dog or cat show? Wasn’t it fun to view all of the animals for sale, especially the adorable babies? It was also interesting to see the wide variety of things for sale at the vendors. You may be surprised to know that events like this exist for bird lovers as well. They are generally known as bird fairs, exhibitions, shows, or expos. Often, owners or breeders will enter birds to be judged and, if they are lucky, win prizes, much like a canine or feline show. Breeders may also sell baby birds of all species, varying from pigeon squabs to little finches to parrot chicks. They will also sell adult birds at these events, or they will sell a breeding pair. It is unlikely that someone will be selling a breeding pair of macaws or cockatoos at a bird fair, however- generally, you will only find them selling breeding pairs of parrotlets, parakeets, cockatiels, doves, finches, or canaries. But one of the best parts of a bird fair is the vendors. Here, you can find anything your avian buddy could ever want, need, or dream of- giant stainless steel cages, the newest spill-free birdfeeder (although most parrot owners would firmly argue that such a thing does not, and will not, ever exist), freeze-dried treats, supplements, toys of all shapes, sizes, and colors, free-flight ‘harnesses’, even bird-themed items for people such as artwork or stuffed animals.

Remember, it probably is a very, very bad idea to bring your bird to a bird show. Generally, it is not even allowed, and you will have to go back home with your bird. If it isn’t prohibited, however, it still doesn’t mean you should do it. Your bird could get parasites or a disease from fellow birds at the fair. All of the screeching and tweeting, and all of the people milling around and talking, could frighten your bird. If your bird becomes frightened, you will probably have to head back home, because your bird could hurt itself trying to escape from a small travel cage. And if it isn’t trying to escape, it could upset other birds or their owners if it is loudly screaming or making other unsuitable vocalizations.

Another fun part of bird fairs are the raffles. Although bird fairs don’t always have raffles or auctions, it is fairly common and generally it isn’t a big surprise if your local bird fair has one. A wide variety of items can be raffled off- birdcages of all sizes, coupons for free avian vet checkups, bird toys, bird food and treats, and playstands. You may also see some bird-themed human items, like paintings, photos, t-shirts, and more.

Bird fairs are fun opportunities to socialize with fellow bird lovers, owners, and breeders, to buy your avian friend some interesting toys or treats –or perhaps a new cage, and, to possibly find a parrot or other bird that you would like to add to your feathered family. Look for bird fairs near you- they can be extremely fun events suitable for the whole family.

Bird Tracking Technology

$

0

Various methods of marking birds for identification are believed to go back as far as Roman times and this was generally done to indicate ownership. The first person to ring birds for scientific purposes was Danish ornithologist Hans Christian Cornelius Mortensen (1856-1921) who put aluminum rings marked with unique numbers and an address, first on the legs of European Starlings, and later on storks, herons, gulls and ducks, with the intention of tracking their movements. The first organized banding scheme was established at the Rossitten Bird Observatory by German ornithologist Johannes Thienemann in 1903.

Since those early days bird banding has been invaluable in gathering data for conservation and scientific purposes. But banding has its limitations, as once birds are set free they are very often only identified again when found injured or dead, and then only if the person finding the bird takes the time and trouble to report it. At best, bird banding provides only a few pieces of the puzzle of bird migration and behavior. However, rapidly advancing technology has opened up new avenues of tracking birds, with the most promising being satellite telemetry, which provides information immediately.

In 2005, satellite telemetry was used by the Wildlife Research Institute (WRI) and the United States Forest Service (USFS) to track Southern California’s Golden Eagles, and this was later expanded to include Montana. Tiny transmitters are attached to the birds and their signals are tracked by satellites no matter where they may travel. Working in conjunction with the National Oceanic and Atmospheric Administration (NOAA) the WRI received data via the internet enabling researchers to determine exactly where the eagles have been and when. The information is so detailed that it can be determined how high the eagles flew, and how fast they were flying. In the event of an eagle not moving, it’s location can be pinpointed and the bird rescued if injured, or recovered if dead.

As plans for alternative energy sources in the form of wind and solar farms move ahead in California, data on migration, nesting and hunting patterns of Golden Eagles will be invaluable in ensuring the survival of this already endangered species. On a wider scale, the cost and availability of satellite telemetry is an obstacle that may be difficult to overcome, particularly in developing nations, and so bird banding remains an important activity for conservationists.

Turkey Vultures and Perpetual Flight

$
0

In their quest for perpetual flight, researchers at Lehigh University have taken note of the turkey vulture’s amazing ability to stay aloft indefinitely with very little effort, as it scans the terrain beneath it for carrion to feed on. In addition to gauging thermals and wind direction with their own sensors, it appears that turkey vultures closely monitor other birds of prey in the area and use the information gleaned from them to determine which areas would best support their effortless soaring. It is thought that they may even keep an eye on the movement of clouds and the swaying of trees to gather information about wind currents and thermals.

Also of interest to aviation researchers, is the turkey vulture’s unique ability to hold its wings in a shallow V-shaped angle for extended periods of time which allows it to stay aloft with little effort, as well as giving it the ability to use sidewinds to its advantage, converting them into speed and altitude at a moment’s notice.

The concept of ‘dynamic soaring’ was first described in the British journal Nature in 1883 by Lord Rayleigh in an article entitled The Soaring of Birds. There he states that a bird cannot maintain its level indefinitely, either in still air or in a uniform horizontal wind, without working his wings. He concluded that if a bird maintained his course for some time, without working his wings, the conclusion can be drawn that either: The course is not horizontal; the wind is not horizontal; or the wind is not uniform – the latter being the principle relating to dynamic soaring.

Turkey vultures, also known as turkey buzzards, or simply buzzards, have a wide range of habitat, being found from southern Canada right down to the southernmost point of South America. These large scavengers favor open and semi-open terrain where they can spot their next meal with ease, feeding almost exclusively on carrion. They roost in large groups, nesting in caves, thickets, or hollow trees. As they do not have a syrinx, they can only make grunting and hissing noises. Legally protected in the United States, and with very few natural predators, turkey vultures have an IUCN conservation status of ‘least concern’.

Bird Atlas Tracks Trends in Britain and Ireland

$

Featuring more than 1,300 maps describing patterns of distribution for nearly 300 bird species, the new British Trust for Ornithology (BTO) Bird Atlas 2007-11 has recently been released to the public. This comprehensive study of bird distribution trends in Britain and Ireland was compiled from data gathered by more than 40,000 volunteers over a period of four summers and four winters. The information was analyzed by scientists and authors Simon Gillings, Dawn Balmer, Brian Caffrey, Bob Swann, Rob Fuller and Iain Downie and compiled into a treasure trove of information for all who are interested in the birdlife of this region.

Among the wealth of interesting information presented in the Bird Atlas is the fact that as many as forty exotic species have taken up residence in Britain and Ireland. These include the white-cheeked turaco from Ethiopia and Sudan; the red-rumped parrot of Australia; the pin-tailed whydah of sub-Saharan Africa; and the Alexandrine parakeet from Sri Lanka and India, as well as zebra finches and Chinese pheasants. While these are most likely originally escapees from private owners, they have adapted to their surroundings and many have started breeding. So, although they are not indigenous to Britain and Ireland, it appears that they are there to stay and should therefore be monitored along with local populations.

This monitoring becomes even more important when exotic species start posing a threat to native birds, as appears to be the case with the ring-necked parakeet from Delhi. These birds were first reported in the wild in Britain in 1971, having escaped from aviaries. The survey notes that there are now more than 30,000 ring-necked parakeets resident across southern Britain and they appear to be moving northwards. As they use holes in trees to lay their eggs, they are encroaching on the nesting territory of the nuthatch and other birds – and are not shy about taking over.

Observations regarding native birds include the disheartening fact that nightingales, yellowhammers and woodcocks numbers are declining. On the other hand it’s been noted that the little egret and avocet is experiencing an increase in numbers. In addition to listing statistics, the Bird Atlas provides explanations regarding changes that have taken place. For example, the decline in Dartford warbler breeding pairs from 3,214 pairs in 2006, to 600 pairs in 2010 is attributed to the harsh winters experienced in two successive years. It’s not all doom and gloom for Dartford warblers though, as the Bird Atlas notes that they have the capacity to recover and expand their range.

The Serious Hobby of Twitching

$

0

The Hollywood film The Big Year presents what seems to be an exaggeration of the extremes birding enthusiasts will go to in boosting their number of sightings, particularly of rare birds, with camaraderie turning to cut-throat competition in the blink of an eye, or the twitch of a feathered tail. But the reality is that competitive birding, referred to as “twitching”, has reportedly become an obsession with some birders as they attempt to beat rivals at adding birds to their list. While this activity is very popular in the United States, according to those in the know, British twitchers are among the fiercest competitors in the world.

There are various definitions of “twitching” and descriptions of “twitchers”, but in general it refers to birding enthusiasts who are prepared to stop whatever they are doing immediately to follow up on reports of birds not yet on their list of sightings, or that they have not yet ticked off their list of birds they hope to see. The verb “twitching” is thought to be a reference to the nervous anticipation, stress and anxiety experienced by a birder in pursuit of his/her hobby which often includes traveling long distances and overcoming physical and other obstacles, with the single-minded goal of getting to see (or hear) an elusive bird. There are also varying rules as to when a twitcher can tick a bird off a list, with some saying that hearing the bird is enough and others insisting the seeing the bird should be the rule. Either way, twitchers are not required to provide photographic evidence of their sightings, so the system relies on honor among twitchers.

As with most serious hobbies, twitching has its own vocabulary, and when a twitcher fails to sight the bird he rushed off to see, he considers himself to have “dipped out”, and if his competitors managed to see the bird, he is likely to feel “gripped off”. Some twitchers have compiled a “life list” of birds they hope to see in their lifetime, while others set goals for a season, or specific time period such as 24-hours, which increases the competitive spirit.

Modern technology has aided twitchers immensely as information on rare bird sightings can be sent out immediately, with updates alerting twitchers to the bird’s whereabouts as they are en route to view it. Based in Norwich in the United Kingdom, Rare Bird Alert has been operating since 1991, with a team of experienced birders making information available to birders fifteen hours a day, every day of the year. Similar organizations exist in other countries where birders take their hobby seriously.

The Plight of the Red Knot

$

Breeding in the Canadian Artic and wintering in Argentina and Chile, red knots undertake an epic migration journey of around 9,300 miles (15,000 km) twice every year. In order to complete the voyage successfully, red knots (Calidris canutus) require top quality food sources, and previously they have found this in abundance in the shape of horseshoe crab eggs in Delaware Bay. However, it’s been noted that red knot numbers have declined drastically since the turn of the century, with one of the main reasons being the decline in horseshoe crabs that have been harvested for commercial gain. Without sufficient fuel, these medium-sized shorebirds may not make it back to their Arctic breeding grounds, or if they do, they may be too weak to breed successfully, and considering that nearly 90 percent of the red knot population use Delaware Bay on their migration route, the lack of food could result in the species becoming endangered, or extinct.

Recognizing this problem, the US Fish and Wildlife Service (FWS) have proposed that red knots be classified as ‘threatened’ under the Endangered Species Act (ESA). Data reveals that there has been about a 75 percent decline in red knot numbers since the 1980s, with the rate of decline increasing sharply after the year 2000, coinciding with the decline in horseshoe crab populations. Red knots arrive at Delaware Bay just as horseshoe crabs arrive on the beaches to lay their eggs in shallow holes they dig in the sand. Each female lays up to 120,000 eggs in batches, which are then fertilized by the male that hitched a ride on her back to the beach. Shorebirds, including the red knot, eat many thousands of these protein rich eggs in the two week period before they hatch.

When red knots arrive at Delaware Bay, they are quite exhausted and emaciated. They need to rebuild their strength and stock up on fat reserves for the arduous journey ahead. As they feast on the eggs, they undergo a number of interesting physiological changes. As documented by the FWS, these include an increase in fat stores, and an increase in size of the chest (pectoral) muscles and heart, while the gizzard, stomach, intestines, liver and leg muscles of the birds decrease in size, all in preparation for the last leg of their migration.

While the decline of horseshoe crab eggs as a food source is a serious problem for red knots, it is not the only problem they face. The FWS notes that climate change is altering the terrain they breed in and impacting their diets on their home turf. Rising sea-levels and coastal development are other issues. But these are beyond the control of conservationists concerned with the plight of migratory birds. What can (and likely will) change is when harvesting of horseshoe crabs takes place, so that when the red knots arrive they have first choice of the horseshoe crabs’ eggs to fuel up for the last leg of their journey.

What is that bird talking about?

“I tried to discover, in the rumor of forests and waves, words that other men could not hear, and I pricked up my ears to listen to the revelation of their harmony.” Gustave Flaubert

Most of us have been conditioned to consider bird’s chirping, singing, or squawking as something like noise. How sad for us. Although a great listener of humans and four legged animals, I’ve been woefully ignorant of the rich discussions taking place in the trees. The most basic understanding of bird language would have enriched my experiences with birds both captive and free.

Soon after being given a Quaker parrot in the summer of 2013, a friend played Jon Young’s video about bird language for me. My eyes (and ears) were opened to a new dimension to the world around me. Just like humans and other mammals, birds make noise to communicate. Young’s insights allowed me to hear Dahlia’s comments and requests as clearly as I do my human friends.

Dahlia clucks, trills, squawks, whistles, sings, kisses, clicks, and purrs.

When I walk away or leave the room or car, she makes an unpleasant squawk. This is obviously an emotional response to something she does not like that serves as an alarm. When I walk back toward her or return to the room or car, she often trills, kisses, or coos.

When I stop singing in the shower, she often squawks. When I resume, she makes adorable sounds celebrating music and interaction as if it is a party.

After six months with Dahlia, our ability to communicate makes us friends and roommates rather than human and animal or worse, “owner” and “pet.” She is wonderful company, a fun dance partner, and great entertainment. She is also demanding with a strong sense of entitlement. It is one of the most intimate relationships I have ever had.

“When we are listened to, it creates us, makes us unfold and expand. Ideas actually begin to grow within us and come to life.” Brenda Ueland

By listening better and more often to Dahlia, I have helped her personality develop. Knowing I will respond to her needs, she is quick to make her desires known.

Playing music she likes encourages her dancing while enhancing her quality of life. Letting her take the lead in games we play makes her more than a toy.

“The activity of interpreting might be understood as listening for the ‘song beneath the words’.” Ronald Heifetz

One game we play is a version of Simon Says. Dahlia only initiates this when I am in the room but not engaging with her, which is telling. I hear a distinct whistle, rhuu-whoo-rhuu as she gets my attention. Recognizing the cue, I copy. She quickly gives me another, wheet wheooo, which I echo. Then wrhoo-ruh-wheet and my ready reply.

If I had not listened for meaning or “the song beneath the words”, I would have thought she was merely vocalizing. Playfully copying her led to another activity making us more like dance partners than jailor and jailbird. The connectedness we share as a result of varied interactions makes us both happier.

Having lived with so many animals over the years I am amazed at birds’ interest and ability for dance. My quaker parrot can’t stop moving to the music. It’s automatic. Maybe we should call song birds song and dance birds.

“An appreciative listener is always stimulating.” Agatha Christie

Some species, like mockingbirds, include “elements learned in the individual’s lifetime” in their songs. Researchers call this appropriation. Many scientists contend that song bird calls include grammatical structure. Undoubtedly, we will be learning about bird communication for years to come.

Birds use what they have to communicate much like humans do. Linguists will tell you that humans do not use all of the sounds our mouths can make. Some languages use more than others, but putting together all of the various sounds human language makes leaves some sounds completely unused. Birds however use all of the possible sounds due to their more limited apparatus.

Birds tell us they are content, happy, excited, angry, bored, and scared. Much of the emphasis on human/bird interaction is on how much human language they can learn or already know. But, if birds understand some of the words they use and understand words that they cannot say, our interaction with them, our relationships, would benefit from humans working on their listening and communicating skills.

Some things to consider:

Why you should listen to your bird
What your bird is telling you
What your bird wants you to know
What your bird is trying to tell you

You and your bird will be happier if you become a better listener.

The 17th annual Great Backyard Bird Count (GBBC) is set to take place from February 14 through to February 17 in multiple locations all over the world. This four day event calls on bird watchers of all ages and levels of experience to count the birds they see in one location over a fifteen-minute period. Participants need only do one fifteen-minute stint, but are welcome to do more than that if they have the time. After tallying the number of individual birds of each species spotted within the fifteen-minute time period, birders enter the data on the GBBC website.

Data gathered from all over the world is valuable to researchers in many ways, particularly when it is compared with data collected in previous years. Information from the GBBC and other projects supported by citizen-scientists help researchers determine the health of various species by monitoring changes in populations; how the weather influences bird populations; changes in the timing of annual migrations; how diseases affect birds in specific regions; and where irruptive species go when they don’t visit the same location as the previous year. It also helps researchers with a comparison of bird diversity within city limits, suburbs, rural areas and reserves.

Through projects like the GBBC, modern technology offers birders the opportunity to be part of a worldwide community, while at the same time gathering information that no team of scientist would ordinarily be able to do. Thousands of people in more than one hundred countries will be participating in the event, which is supported by the National Audubon Society, Cornell Lab of Ornithology and Bird Studies Canada. It’s also the perfect opportunity for children to learn about the importance of birds within their environment, and how birds are an indicator of the general health of the ecology. So, why not do your bit and register for the 2014 Great Backyard Bird Count.

Some Fascinating Facts About Pelicans

$

Based on the oldest recorded pelican fossil found at Luberon in southeastern France belonging to the Early Oligocene era, it has been deduced that pelicans have existed virtually unchanged for at least thirty million years. Fossils of several birds from the Pelecanus species have been identified elsewhere in the world – South Australia; Siwalik Hills, India; Bavaria, Germany; Idaho, United States; Odessa, Ukraine; and North Carolina, United States – backing up this claim. Today there are eight living pelican species distributed around the world and some of which are considered ‘vulnerable’ or ‘threatened’ by the IUCN, and all of which use their amazingly elastic pouches to catch fish.

With the exception of the brown pelican, which dives for fish and snatches it up in its bill, pelicans usually form cooperative groups for their fishing expeditions. They either swim along in a line or U-shape formation, beating their wings on the surface of the water to drive the fish into a group in the shallows where the pelicans scoop them up in their pouches. Contrary to popular belief, pelicans do not store fish in their pouches, but swallow them almost immediately upon catching them. Baby pelicans feed by retrieving fish from the throats of their parents.

Pelicans are very social birds, traveling in flocks and breeding in colonies, either along the coastline or inland alongside rivers and lakes. The brown pelican (Pelecanus occidentalis) was at one time considered to be ‘vulnerable’ in North America – primarily due to poisoning by chemical pesticides such as the notorious DDT which devastated the populations of many seabirds – but recent reports indicate that significant recovery has taken place and the birds’ conservation status is now that of ‘least concern’.

The Dalmation pelican (Pelecanus crispus), found in South-eastern Europe through to India and China, has the IUCN conservation status of ‘vulnerable’, while the Peruvian pelican (Pelecanus thagus) found on the Pacific Coast of South America, and the spot-billed pelican (Pelecanus philippensis) found in Southern Asia, are both considered to be ‘near threatened’. The other pelican species – pink-backed pelican (Pelecanus rufescens) found in Africa, Seychelles and southwestern Arabia; the American white pelican (Pelecanus erythrorhynchos) found in North America; the great white pelican (Pelecanus onocrotalus) found in the eastern Mediterranean, Malay Peninsula and South Africa; and the Australian pelican (Pelecanus conspicillatus) found in Australia, New Guinea, New Zealand, Bismarck Archipelago, Fiji and Walacea are all listed as being of ‘least concern’ from a conservation standpoint.

Irruptive Migration of Bird Species

$
0
0

The main reason birds migrate is to ensure they have access to food all year round. For some bird species this may mean flying half way around the world, and their migration patterns are so predictable that birders arrange special events to welcome the weary travelers to their wintering ground, as well as to see them off when they depart. For centuries, farmers have looked to the departure and arrival of local birds as an indication of what the seasons hold, while mariners judged ocean currents and the nearness of land by the birds they encountered. Some migrating bird species are somewhat less predictable and these are referred to as irruptive migrants, with their migration habits being referred to as irruptive migration.

Some species may have a cycle of irruptive migration where they visit an area every two or four years and are therefore still predictable, while others are completely random. Reasons for irruptive migration are varied, but the most common cause is a lack of food in their normal wintering grounds. Birds that depend on birch, pine, spruce and maple seeds and catkins are known to irrupt when these trees produce poor crops. As their name suggests, crossbills have unique crossed bill-tips designed to pry conifer cones open and extract the seeds. They do not have the luxury of choosing an alternative food source and are obliged to find food they can access. As these seeds are also rodent food, if they fail to appear or produce an insufficient crop for demand, raptors may also leave the area in search of a more readily available food source.

Irrespective of what the motivating factors are for irrupting, it is virtually impossible to predict which species will irrupt in any given year and where they will migrate to, however the following species have been noted for regularly irrupting: pine siskins, bohemian waxwings, boreal chickadees, evening grosbeaks, purple finches, pine grosbeaks, common redpolls, red crossbills, white-winged crossbills, northern shrikes, hoary redpolls, red-breasted nuthatches, snowy owls, great grey owls and rough-legged hawks.

While birders generally welcome seeing unfamiliar birds at their backyard feeders, they should be aware that sometimes the unexpected visitors, particularly if they arrive in great numbers, can intimidate the locals in their quest for food. This can be overcome by setting out extra feeders and spacing them as far apart as possible. Also ensure that plenty of water is provided and water sources are cleaned regularly. Then sit back, relax, and enjoy the sight of feathered friends from far away.

The Spectacular Himalayan Monal

As one of the more colorful members of the pheasant family, the Himalayan monal features iridescent plumage in shades of blue, green and red. Its back is purple-black, with a dark brown breast, light brown tail feathers and white throat. Its white rump patch is only visible in flight. The male of the species boasts a metallic green head crest with spoon-shaped feathers, while the female has a shorter, brown colored crest. The Himalayan monal (Lophophorus impejanus) is the national bird of Nepal and is referred to as the Danphe, and it is the official bird of the Indian state of Uttarakhand, where it is referred to as the Monal.

The Himalayan monal uses a number of different call types to communicate with other birds in its flock, and to warn off intruding birds. In addition to using courting calls, males bob their head crests and fan their tail feathers to attract the attention of a mate. Also, during breeding season, males become far more vocal, calling throughout the day instead of only in the early mornings. After mating, the female scrapes a hollow in the ground to lay her three to five eggs in. Only the female incubates the eggs, but the male will remain close by to protect the female and their offspring until they fledge. By the age of six months, young Himalayan monals are independent of their parents and will search for food and find mates to continue the cycle.

Himalayan monals have powerful legs and strong curved beaks to allow them to dig into hard mountain soil in their search for tubers, shoots, seeds, insects and berries. Birders can be on the lookout for these stunning birds when they come across areas of turned over soil on hillsides, as this the telltale evidence of their foraging activities.

As a high-altitude species, Himalayan monals remain between 2,100 and 4,500 meters above sea level, and during the summer months generally move above the tree-line of their mountainous terrain, but in winter will find shelter in the rhododendron, coniferous and mixed forests of Nepal and the other countries in which it is found, which includes Bhutan, northeast India and southern Tibet.

The melody of wheezy whistle-like calls pulled my eyes upward in search of the Black-bellied Whistling ducks that broke through my daydream.The sound of my shoes crunching along the pebble strewn path, the throaty grunts and croaks of the nesting Great Egrets and Neotropic Cormorants, and the intermittent humming of the bees that flit from one honeysuckle vine to the next had lulled me into a pleasant state of serenity.

Embodying both the spirit of discovery and tranquility, Shangri-La Botanical Gardens & Nature Center nurtures the concept of a harmonious relationship with nature and man. Located in the historic Southeastern Texas town of Orange, nestled on the banks of the Sabine River, Shangri-La offers nature enthusiast an unhampered glimpse at the workings of mother nature. The transition from winter to spring brings about an opportunity for young and old alike to witness the nesting, mating, and hatching of the winged residents that have turned a manmade lake into a heronry. At about 15 acres and in the heart of the botanical garden, Ruby Lake plays host to more than 5,000 birds annually and as many as 17 species seasonally. Along with the Egrets and Cormorants mentioned earlier, Anhingas, Roseate Spoonbills, and a variety of ducks call Ruby Lake home. Built from cypress logs that lay at the bottom of the river for decades, the Bird Blind provides birdwatchers of all ages and mobility a chance to observe nature unimpeded. Reaching the blind and this sanctuary is much easier than one might imagine. Just a short stroll down a gravel path dappled with sunlight and flowers that branches off the main path running through the gardens will get you there. The path is expertly maintained and with a wheelchair ramp into the blind, no one is denied access to this natural spectacle.

You are offered your first glimpse of the secluded lake and it’s inhabitants off to the right as the winding path leads up to the bank where there lay a handful of turtles basking on a fallen cypress log. In this small alcove, there are a sprinkling of Great Egret nests amongst the cypress trees, but the truly impressive views come from within the Bird Blind, which is just a little further up the path. Located just next to a stand of cypress trees flocked in white with hundreds of Great Egrets and their nests, the blind presents the observer with views of new hatchlings still bobbing and bumbling, trying their best to gain control of their head, wings, and legs. Open Tuesday-Saturday 9am-5pm, there is more than enough time to grab a seat on one of the sinker cypress benches, refresh yourself from the water fountain provided, and watch the comings and goings one of the most majestic creatures to grace the waterways of the south.
