Vermont's first confirmed Eurasian Collared-Dove

Vermont's first confirmed Eurasian Collared-Dove has provided a rare, unexpected sight for birders from all over the region since its presence was made "public" on November 25. The bird has been a reliable visitor since mid-month at the feeders of Norwich residents John and Dianne Dunn, who quickly realized that the large, pale dove chasing their resident Mourning Doves was out of the ordinary. Their initial ID was right on target, and they called VCE to inform us about the first-state record. A couple of listserv messages later, and birders have been congregating in the Dunn's back yard.

Few have been disappointed so far, as the bird rarely fails to appear, especially during morning or early afternoon hours. The Dunns, who live at 1460 Union Village Road, are extremely welcoming and accommodating to birders seeking to add Eurasian Collared-Dove to their life lists. All visitors should, of course, respect the Dunns' privacy.

While a definite surprise in central Vermont during late November, the Eurasian Collared-Dove was bound to make an appearance sooner or later. Introduced into the Bahamas in the mid-1970s, probably as a released cage bird, the species has spread very rapidly and is now established throughout the southeastern United States. A smattering of records exist across the country as far west as California, and north to British Columbia and Saskatchewan. The closest previous occurrences of this species to Vermont were of birds in Massachusetts and New York. The spread of Eurasian Collared-Doves across North America is still an evolving situation -- the full expansion its final range and the impacts it may have on other bird species remain to be seen.

Ecologists sound out new solution for monitoring cryptic species

Ecologists have at last worked out a way of using recordings of birdsong to accurately measure the size of bird populations. This is the first time sound recordings from a microphone array have been translated into accurate estimates of bird species' populations. Because the new technique, reported in the British Ecological Society's Journal of Applied Ecology, will also work with whale song, it could lead to a major advance in our ability to monitor whale and dolphin numbers.

Developed by Deanna Dawson of the US Geological Survey and Murray Efford of the University of Otago, New Zealand, the technique is an innovative combination of sound recording with spatially explicit capture-recapture (SECR), a new version of one of ecologists' oldest tools for monitoring animal populations.

Birds communicate by singing or calling, and biologists have long counted these cues to get an index of bird abundance. But it is much harder to work out the actual density of a bird population because existing methods need observers to measure either the distance to each bird, or whether they are within a set distance from the observer. This is straightforward if birds are seen, but difficult when birds are heard but not seen.

According to Dawson: "We devised a way to estimate population density of birds or other animals that vocalise by combining sound information from several microphones. A sound spreading through a forest or other habitat leaves a 'footprint'. The size of the footprint depends on how quickly the sound attenuates. Mathematically, there is a unique combination of population density and attenuation rate that best matches the number and 'size' of the recorded sounds. We used computer methods to find the best match, and thereby estimate density."

Dawson and Efford developed the method by recording the ovenbird – a warbler more often heard than seen – in deciduous forest at the Patuxent Research Refuge near Laurel, Maryland, USA. They rigged up four microphones close to the ground in a square with 21 metre-long sides. Over five days, they moved the microphones to 75 different points across their study area and recorded ovenbirds singing.

They chose the ovenbird as the species from which to develop the method because of its concise, distinctive song and because the males sing from the lower layers of the forest.

The new acoustic technique gives a more accurate estimate of bird numbers than using nets to capture birds, which can be stressful for the birds as well as time consuming for the researchers.

As well as helping assess populations of cryptic bird species such as the ovenbird, the new technique might be applied to measuring hard-to-reach populations of marine mammals, such as whales and dolphins. Developing ways of estimating whale and dolphin numbers acoustically is seen as critical for understanding these species' populations.

Recording the sounds has other benefits, too. "Sound intensity and other characteristics can be measured from the spectrogram – the graph of the sounds – to improve density estimates. Archiving the sounds also makes it possible to re-examine them, or to extract additional information as analytical methods evolve," says Dawson.

The 110th Christmas Bird Counts in Vermont

The 110th Christmas Bird Count will run from December 14, 2009 through January 5, 2010. Last year, thousands of volunteers counted nearly 60 million birds across the Americas and beyond. Each count occurs in a designated circle, 15 miles in diameter, and is led by an experienced birder, or designated “compiler”. Read more to learn where Vermont CBCs are located, date of counts and compiler contact information...

The longest running citizen science program in the world, the count originally began on Christmas Day in 1900 when ornithologist and legendary birder Frank Chapman posed an alternative to an earlier traditional holiday "side hunt." Chapman proposed “hunting” birds to record their numbers. Instead of firing a shotgun, now we have an annual snapshot. Decades of data have added up to results envied by other scientists who don’t enjoy such a fleet of volunteer help, or creatures as easily seen and counted as birds.

While there is a specific methodology to the CBC and you need to count birds within an existing Christmas Bird Count circle, everyone can participate! If you are a beginning birder, you will be able to join a group that includes at least one experienced birdwatcher. If your home is within the boundaries of a Christmas Bird Count circle, then you can stay home and report the birds that visit your feeder or join a group of birdwatchers in the field. If you have never been on a CBC before and you want to participate in a count this year, including feeder counting, please contact your count compiler prior to the count.

Would you like to explore the data from seasons past? Visit the Christmas Bird Count home page to create your own graphs and tables!

Killer fungus threatening amphibians

Amphibians like frogs and toads have existed for 360 million years and survived when the dinosaurs didn't, but a new aquatic fungus is threatening to make many of them extinct, according to an article in the November issue of Microbiology Today.

The fungus, Batrachochytrium dendrobatidis (Bd), was found to be associated with waves of amphibian extinctions in Central America and north-eastern Australia in the 1990's. Bd infects over 350 amphibian species by penetrating their skin, but little else is known about where it came from and how it causes disease.

The earliest published record of Bd is from a specimen of an African clawed frog in 1938 from South Africa. Around this time there was a huge trade in clawed frogs when they were used in one of the earliest human pregnancy tests. The global exportation of the clawed frog is likely to have spread Bd around the world. The infection is spread by fungal spores released into the water supply from imported infected animals.

Researchers are trying different approaches to treat existing Bd infection. Some are treating tadpoles with antifungal drugs, whilst more innovative approaches involve introducing 'probiotic' bacteria that naturally secrete antifungal compounds which kill Bd on amphibians' skin. To help limit the spread of infection, the World Organization for Animal Health (WOAH) now recommends screening imported amphibians for presence of Bd.

Nine Birds Added to Québec List of Threatened and Vulnerable Species

Serge Simard, Québec’s Minister for Natural Resources and Wildlife, has announced the addition of a further nine bird species to the province’s list of threatened and vulnerable species.

Following modifications made to the Règlement sur les espèces fauniques menacées ou vulnérables et leurs habitats, the Caspian Tern and the Roseate Tern, together with the Cerulean Warbler, Yellow Rail, and Red-headed Woodpecker, join the Horned Grebe, Loggerhead Shrike, and Piping Plover as threatened species. The Harlequin Duck, Barrow’s Goldeneye, Least Bittern, and Bicknell’s Thrush join three raptors – the Golden Eagle, Bald Eagle, and Peregrine Falcon (subspecies anatum) – as vulnerable species. These modifications to the regulations will result in enhanced protection for these birds and their habitats.

At the moment, five additional birds are on the list of species susceptible to be designated as provincially threatened or vulnerable: the Nelson’s Sharp-tailed Sparrow, Grasshopper Sparrow, Short-eared Owl, Golden-winged Warbler, and Sedge Wren. For further information, and for the complete list of threatened and vulnerable species in Québec, visit the website of the ministère des Ressources naturelles et de la Faune.

Look What the Cat Dragged In



Banding a Bobolink in S. America
During the course of her studies on the Bobolink throughout the western hemisphere, Dr. Rosalind Renfrew of the Vermont Center for Ecostudies has captured and recruited 433 of these charismatic songbirds as research subjects. On the right leg of each she places a tiny aluminum bracelet bearing a unique number, a bit like an avian Social Security number. Renfrew then releases each bird to fateful winds, hoping against all rational odds that some day, somewhere, anywhere, one of them will be recaptured.

Bobolink No. 0961-10071 got his bracelet while Renfrew was working in a rice field in San Juan, Bolivia, on January 30, 2006. Then he was gone.

“The odds than any of these Bobolinks would be found anywhere, dead or alive, were essentially zero,” says Renfrew, a biologist with the Vermont Center for Ecostudies in Norwich, Vermont. “They could be flying in a range that extends thousands and thousands of square miles.”

But just this past spring, three and a half years after she had banded him, in what could only be described as a case of avian shock and awe, Bobolink No. 0961-10071 turned up in Vermont. Renfrew had expected to win the lottery before relocating this bird – and she doesn’t even play. And here’s what is most amazing about this impossible discovery:

• Bobolink No. 0961-10071 was rediscovered at least 4,300 miles (as the crow flies) from where he was banded Bolivia. This marked the first time a Bobolink banded on its wintering grounds had been recovered on its breeding grounds (or vice versa).

• Because Bobolink No. 0961-10071 turned up three years after he was banded, he flew at least 35,000 miles in migration between South America and North America before that fateful June day in Vermont.

• Bobolink No. 0961-10071 was found in Chelsea, Vermont, only 12 miles from Renfrew’s home.

“I’m still shaking my head in disbelief,” says Renfrew. “To catch a songbird on its wintering grounds in South America and have it turn up essentially at my door thousands of miles away, well, it’s practically impossible.”

Finally, and poignantly, Bobolink No. 0961-10071, after flying all those miles, came to Renfrew’s attention only because he was delivered to a homeowner by a house cat.

The Bobolink’s odd, electronic song and flashy yellow-white-and-black plumage make it a charming summer songbird. Welcomed each spring to meadows, pastures and other grasslands across North America, Bobolinks aren’t always well received in South America each winter. There they feed in commercial rice fields, where farmers consider them agricultural pests and use pesticides that are highly toxic to birds.

“Rice may be a bit like fast food,” says Renfrew. “It’s easy to get but can be unhealthy for Bobolinks.”

In earlier research trips to South America, Renfrew found Bobolinks gathered into remarkable groups numbering up to 130,000 birds and feeding in rice fields. The discovery was exciting yet worrisome. Scientists and conservationists have for decades tracked a steady decline in Bobolink populations.

“So many Bobolinks concentrated so densely makes them more vulnerable,” Renfrew explains. “If only a handful of these large flocks were to disappear, we could lose a significant portion of a population that is already depleted.”

With a prestigious grant from the National Geographic Society, Renfrew is using innovative technology and science to track and study Bobolinks. She is analyzing feathers to determine the degree to which Bobolinks rely on commercial rice fields. And she is equipping some Bobolinks with geolocators – tiny “bird backpack” devices that actually track a wandering Bobolink’s whereabouts throughout the year.

As it turned out, Bobolink No. 0961-10071 could not be salvaged. Yet it unwittingly established for Renfrew a direct link between Vermont and Bolivia.

“When I travel by plane from my home in Vermont halfway across the hemisphere to study these birds, I gaze out the window and try to imagine a bird weighing only an ounce making that same journey” she says. “The life and death of this particular Bobolink, its amazing feat of migration, and the connection between the continents is now more real for me than ever.”

UCLA biologists, colleagues solve mystery contemplated by Charles Darwin

When Charles Darwin visited the Falkland Islands during the voyage of the Beagle in 1835, he saw a wolf-like species, wrote about it in his diaries and correctly commented that it was being hunted in such large numbers that it would soon become extinct. Darwin was baffled by how this animal got on the islands, and it figured heavily in the formation of his ideas on evolution by natural selection. Now, UCLA biologists and colleagues have analyzed DNA from museum specimens, including one collected by Darwin, and have solved the puzzle. Their results surprised them.

Focus on Science: 'Poisonous' Birds -- Look, But Don't Touch

Although rare in the avian world, several species of birds smell or taste bad, and a few are even poisonous – most notably, the Blue-capped Ifrit and five species of pitohui in New Guinea. These approximately Robin-sized songbirds contain nerve-paralyzing batrachotoxins that are among the most toxic natural substances known. The compounds do not serve to kill prey, but to repel or kill external parasites (e.g., lice, mites) and predators (e.g., snakes, hawks, arboreal mammals, and humans).

The Hooded Pitohui (Pitohui dichrous; bottom bird on Science magazine 30 October 1992 cover above) is the best-studied of these unusual species. A single feather from the breast or back of this bird from a certain geographic locality, if placed on one’s tongue, “would cause a burning, tingling sensation that would last for several hours or overnight. Merely handling these birds...caused [the researchers] to sneeze, experience watery eyes and runny noses, and generally respond as if [they] were having allergic reactions.”

Toxins are most concentrated in skin and feathers, much less so in heart and liver, and least in skeletal muscle. Skin and feathers are more toxic on the back and breast than elsewhere. Since the outside of the bird is where parasites or predators are most likely to encounter toxins, these differences are consistent with their role in providing chemical defense.

Pitohuis do not manufacture the toxins from scratch, but obtain them from their food, most likely certain small beetles. The presence of toxins in internal organs shows that the birds do not merely apply them topically to skin and feathers. Furthermore, since these compounds would normally poison muscles and the liver, their presence in these organs raises the question of how the birds remain unaffected by them. The birds may have evolved biochemical means to resist the toxins internally, but these have yet to be explored.

Levels of toxins vary markedly among individuals and geographic localities, chiefly those in the skin and feathers. The causes of such variation are unknown, but may be related to the mechanisms by which the birds acquire toxins in their diet and incorporate them into their feathers.

The skin of pitohuis has the same tissue structure as that of other passerine birds and does not appear to have any obvious modifications for storing or secreting toxins. Avian skin in general secretes fatty substances and continually sheds cells from the surface. Thus, pitohui skin may be pre-adapted for confining toxins and ridding them from the body. The poisons could be taken up and stored temporarily in the lipids produced by the epidermal cells.

If you go to New Guinea to see these rare birds, look, but don’t touch!

IUCN Red List Update

The International Union for Conservation of Nature (IUCN), the world’s oldest and largest global environmental network, has released its latest update of the IUCN Red List of Threatened Species. Of the 47,677 assessed species, the 2009 update shows that 17,291 are threatened with extinction. This includes 12% of all known birds. Of the world’s 9998 bird species, 137 are Extinct or Extinct in the Wild, with 192 Critically Endangered, 362 Endangered, and 669 Vulnerable.

BirdLife International is the Red List Authority for birds. The latest BirdLife evaluation of the world’s birds did include some good news stories. For example, effective conservation efforts have resulted in three species being downlisted from Critically Endangered to Endangered, to reflect a lower level of threat: Lear’s Macaw (Brazil), Chatham Petrel (New Zealand), and Mauritius Fody (Mauritius).

Vermont eBird takes wing

BurlingtonFreePress.com - Burlington,VT,USA

It was an enduring love and life-long pursuit of “gobs and gobs” of data mixed with a hardcore birding passion that led Vermont Center for Ecostudies scientist Kent McFarland, 43, of Woodstock to coordinate the Web site Vermont eBird.

The site is the first state portal in the country for the national Web site eBird.org, a real-time, online checklist program that has revolutionized the way the birding community reports and accesses information about birds.

BALD EAGLE SHOT IN MILLSFIELD, N.H.: REWARD OFFERED FOR INFORMATION ABOUT SHOOTING

Officials are seeking information to aid an investigation into the shooting of a juvenile bald eagle off the Millsfield Loop Road in Wildlife Management Area B, in Millsfield, northern New Hampshire, on or about October 22, 2009.

Anyone with information should call the New Hampshire Fish and Game Department Operation Game Thief 24-hour hotline at: 1-800-344-4262, or report online anytime at http://www.HuntNH.com/OGT. Callers may remain anonymous.

New Hampshire Fish and Game Department’s conservation officers and special agents of the U.S. Fish and Wildlife Service are conducting a joint investigation into the incident. The U.S. Fish and Wildlife Service is offering a reward of up to $2,500 to the person or people who provide information leading to a conviction under the Bald and Golden Eagle Protection Act.

Local sportsmen discovered the injured bald eagle and notified the New Hampshire Fish and Game Department. A licensed wildlife rehabilitator is caring for the eagle. Examination of the eagle revealed it had been shot with a shotgun and sustained a fractured wing and other injuries. A veterinarian expects the wing will heal well enough for the eagle to fly again and for it eventually to be released into the wild. The New Hampshire moose and small game hunting seasons were open at the time the eagle was found.

In addition to the Eagle Act, state laws and the federal Migratory Bird Treaty Act protect bald eagles. Until 2007, bald eagles were also protected under the Endangered Species Act.

ROSEATE TERN: THE NOVA-SCOTIA/MASSACHUSETTS CONNECTION

Biologists from Mass Audubon’s Coastal Waterbird Program, the USGS (Patuxent Wildlife Research Center), and Bird Studies Canada were excited to find a dozen Canadian-hatched Roseate Terns at staging sites on Cape Cod, Massachusetts, over a 38-day period from 14 August to 21 September 2009.

The Canadian-banded terns were banded as chicks during the summer of 2009 on Country Island, Nova Scotia, by staff from Environment Canada’s Canadian Wildlife Service. Each juvenile tern carried color leg-bands which made them visible among thousands of Roseate and Common terns staging at eight different sites on Cape Cod. Not insignificantly, Country Island where the terns were banded is a Important Bird Area (IBA) in Nova Scotia. In addition most of the color-marked terns were also relocated at one of two highly significant Massachusetts IBAs located on Cape Cod.

The meticulous survey of color-banded terns at these IBA sites is vital to improving our understanding of the nesting, staging behavior, and migratory timing of Roseate Terns, a species classified as Threatened in Canada and Endangered in the northeastern U.S. Such observations also underscore the significance of IBAs in prioritizing habitat significance at the landscape level. Currently the northeastern population of Roseate Terns which is principally located between the south shore of Long Island, New York and Nova Scotia, Canada, contains approximately 3,000 pairs, with Massachusetts supporting the majority of the population. In 2009 the Massachusetts population was comprised of approximately 1,300 pairs.

Growing environmentally friendly rice in South America

arrozThe Spanish Ornithological Society (SEO/Birdlife) and the Grasslands Alliance will initiate a pilot to explore ways to grow rice in a more environmentally friendly way in the Southern Cone. The Bobolink and the Upland Sandpiper are among the migratory bird species breeding in Vermont that will likely benefit from ecologically-produced rice in South America.

In the Argentine Province of Santa Fe, NGO Aves Argentinas will be developing bird refuges in rice fields as part of a "bio-remedy" strategy for areas which have suffered from the impact of lead shot from duck hunting.

"The lead has been accumulating in the environment, and neither rice-producers nor hunters have realized what has been happening," said Rubén Favot, a rice producer and the recently posted Secretary of Production and Tourism of San Javier, Argentina. "Today measurements taken by experts in eco-toxicology show the presence of residues both in the water and in the soil."

In Paraguay, the rice company Agriplús and NGO Guyra Paraguay ("Bird Paraguay") have joined forces to begin trials to produce organic rice. "It's possible that we won't be able to install this type of cultivation yet, but working with fewer costs seems to be an achievable target, which not only favors our environment, but also our economy", is the opinion of the Manager Diego Dominguez.

In addition to the pilot trials in each country, the project will fund a convention of interested rice-growers in a First Meeting of Rice Cultivation and Nature Conservation.

Key Findings on the Health of Vermont Forests

The Vermont Monitoring Cooperative has completed a comprehensive new report synthesizing over 20 years of monitoring and dozens of VMC cooperators' research, including work by the Vermont Center for Ecostudies.

The Vermont Monitoring Cooperative (VMC) was established in 1990 to track changes occurring in Vermont’s forests. Only limited information about the health and baseline conditions of forested ecosystems was available at that time. Vermont lacked the ability to perceive subtle changes in ecosystem condition over time and thus to be able to identify forces affecting forest ecosystem health and productivity. In addition, there was
no dedicated, centralized, and stable location for storing, maintaining, and
distributing important ecological data. VMC was envisioned and created to
collect, assemble, and distribute highquality, documented data and informationto better understand environmental changes and their impacts on forested ecosystems. Understanding the interactive nature of environmental changes required ecosystem-scale, integrated, multidisciplinary monitoring and research based on sound science. Those concepts lie at the heart of the Vermont Monitoring Cooperative’s existence.

This report offers a sampling of the extraordinary amount of information VMC has assembled in its first 18 years. While VMC research focuses primarily on the health of Vermont’s forests, forest ecosystems are complex
entities, affected by weather and climate, by natural and anthropogenic disturbances, and by the long reach of time. And everything in the forest relies on a web of connections, many of which are just now beginning to be understood.

Consider the tiny, reclusive Bicknell’s thrush, a major topic of VMC research efforts. Living at the top of Vermont in our most isolated areas, the bird is nevertheless buffeted by climate change, which alters its habitat both in New England and its wintering grounds in the Caribbean; by atmospheric mercury pollution, which has found its way into its blood
and feathers; and by the presence of happy skiers, who build trails ever higher on the sides of mountains. A goal of VMC is to learn how people can live side-by-side with the thrush, the salamander, and the moose, using the manifold resources provided by Vermont forests, always with an eye
toward a sustainable future.

This report represents the written contributions of 19 cooperators, but collective efforts of dozens of researchers from varying backgrounds and disciplines working collaboratively to compile and tell the stories contained
in this document. To the extent possible, the report is a multidisciplinary synthesis. The majority of datasets in the VMC data library can be broadly characterized under the following section titles of this report: The Health
of Our Forests, Weather and Climate in Vermont, and Monitoring Atmospheric Deposition. This report covers topics including the effects of land-use change on biodiversity, habitat and population levels of many animal species, as well as the effects of alpine development on the
environment. It includes current trends in meteorological parameters such as air temperature, relative humidity, and cloud cover in the Champlain Valley and Vermont.

Also discussed are current conditions and recent trends relating to atmospheric deposition, including transport, acidification of lakes and streams, ozone, and mercury in the environment. Also explored are factors influencing forest health, diversity, structure, productivity, and forests’ ability to store carbon to help mitigate the effects of greenhouse gas
accumulation in the atmosphere.

The information in this report is intended as an introduction to the body of research that has been amassed over time, and which is growing daily. Numerous scientific papers have been published using VMC data, some of which are referenced here. We have tried to highlight successes where VMC data have influenced state, regional, or national policy or where research results have helped alter the behavior of would-be polluters. As an organization, VMC believes that it has an important and timely story to tell.

Conference: Reversing the Decline of Neotropical Migratory Bird Species and Protecting Their Habitats

The Bird Conservation Alliance (BCA) is a network of nearly 200 organizations, including the Vermont Center for Ecostudies (VCE), working together to conserve native wild birds and their habitats. The BCA, which is facilitated and staffed by American Bird Conservancy, will be hosting an all-day educational conference in the Cannon Caucus Room at The Cannon House Office Building in the U.S. Capitol, Washington, D.C., on November 12th from 9:30 am to 4:30 pm. The theme is "Reversing the Decline of Neotropical Migratory Bird Species and Protecting Their Habitats."

The meeting will feature keynote addresses from leaders from the Environmental Protection Agency, U.S. Department of Interior and the U.S. Fish and Wildlife Service, and a series of expert panels will review the multiple threats migratory birds currently face and discuss strategies to solve these problems. Everyone is welcome. If you would like to attend please Register Today!
