Penguins in Alaska?
(6/5/2007) Penguins found in Alaskan waters likely reach the Northern Hemisphere by fishing boat rather than by swimming, report University of Washington researchers.


10-20% of birds extinct by 2100 due to global warming, deforestation
(6/4/2007) Ten to twenty percent of the world's terrestrial bird species could be threatened with extinction by 2100 due to climate change and habitat destruction reports a study published in the June 5 issue of the journal PLoS Biology. The numbers are in line with estimates published last year in The Proceedings of the National Academy of Sciences. Combining future projections on global warming, agricultural expansion and human population growth from the global Millennium Ecosystem Assessment with current geographic ranges of the world's 8,750 species of terrestrial birds, researchers Walter Jetz, David Wilcove, and Andrew Dobson estimate that 950 to 1800 species may be condemned to extinction by 2100.


New species of hummingbird discovered in Colombia
(5/15/2007) Ornithologists have discovered a previously unknown blue-and-green-throated hummingbird species in a cloud forest in Colombia, reports BirdLife International, a conservation group. The bird, called the gorgeted puffleg, measures up to 4 inches (10 cm) in length.


More birds killed by cats than wind turbines
(5/9/2007) Last week's report by the U.S. National Academy of Sciences (NAS) on the environmental impact of wind farms warned that turbines may kill up to 40,000 birds per year, a toll that makes some question the clean energy source is worth the trouble.


Global warming will hurt migratory birds
(5/7/2007) 84 percent of migratory birds have the potential to be affected by climate change warned the United Nations Monday. Lowered water tables, changes in food supplies and prey range, rising sea levels, and increased storm frequency are the greatest threats to birds, said officials with the African Eurasian Migratory Waterbirds Agreement (AEWA) and the Convention on Migratory Species (CMS), two United Nations Environment Programme (UNEP)-led Treaties for the conservation of wildlife.


Commercial hunting may be biggest threat to tropical rainforests
(5/1/2007) Commercial hunting is decimating wildlife populations across the tropics and may be one of the gravest threats presently facing rainforests, reports a series of studies published in the May issue of the journal Biotropica. The research reveals that large-scale loss of wildlife is already affecting forest health and regeneration.


New bird species discovered in the South Pacific
(4/19/2007) University of Florida scientists have discovered a new genus of frogmouth bird in the Solomon Islands. The findings are published in the April edition of Ibis: The International Journal of Avian Science.


Tear-sucking moth in Madagascar feeds on bird eyes
(4/10/2007) Biologists have documented the first known case of moths feeding on the tears of birds. The research, published in the January 4 2007 issue of the journal Biology Letters, reports that Hemiceratoides hieroglyphica 'attacks sleeping birds in Madagascar' using its sharply barbed proboscis to penetrate the bird's eye. While similar behvaior has been reported in mammals, this is the first known case of tear-feeding on birds.


Can penguins be used as bio-indicators of climate change?
(4/4/2007) Scientists at the University of Birmingham are working to determine whether the king penguin can be used as a bio-indicator for global warming.


Chernobyl birds prefer to breed in sites with low radioactivity
(4/3/2007) Birds appear to prefer breeding sites with lower levels of radiation, according to research conducted in the immediate vicinity of the Chernobyl nuclear disaster in Ukraine. The study, published in the current edition of Proceedings of the Royal Society B: Biological Sciences, may be the first to look at the effects of radiation on animal breeding behvaior in the aftermath of Chernobyl.


Photos of world's tiniest owl, recently found in Peru
(3/23/2007) One of the world's smallest owls was spotted for the first time in the wild by researchers monitoring the Area de Conservacion Privada de Abra Patricia -- Alto Nieva, a private conservation area in northern Peru, South America. Biologists consider the Long-whiskered Owlet (Xenoglaux loweryi) "a holy grail of South American ornithology."


Fruit-eating birds at particular risk from Indonesian deforestation
(3/20/2007) A new study on the island of Sulawesi in Indonesia confirms the critical importance of fig trees to the rainforest ecosystem. The research has implications for wildlife conservation in an area of high rates of forest loss from agricultural conversion and logging.


Evolution is faster in temperate zones
(3/15/2007) A new study argues that temperate zones are hotbeds of evolution, not tropical areas as conventionally held.


Ivory-billed Woodpecker sighting may be a mistake
(3/14/2007) A new study casts doubt on the apparent rediscovery of the Ivory-billed Woodpecker in Arkansas. J. Martin Collinson, a researcher at the University of Aberdeen in Scotland, says that the sighting of the thought-to-be-extinct bird is a case of mistaken identity. Using video analysis, Collinson argues that ornithologists have confused the Ivory-billed Woodpecker (Campephilus principalis) with the similar Pileated Woodpecker (Dryocopus pileatus).


Pigeon beaks have navigation system
(3/14/2007) Birds may use sensors in their beaks to navigate long distances without getting lost according to a new study published in the scientific journal Naturwissenschaften. German scientists found iron-containing structures in the beaks of homing pigeons that might enable the birds to use the earth's magnetic field for navigation.


Birds follow racoon-like coati to find food
(3/8/2007) A number of rainforest bird species are known to follow columns of army ants eating insects and other animals as they try to escape the marauding ants. Now the behvaior has been documented in birds that follow the coatimundi, a racoon-like mammal, as it forages in the rainforest.


Bird species rediscovered after 139 years
(3/6/2007) A wetland bird that has been 'lost' for nearly 140 years was rediscovered at a wastewater treatment plant in Thailand according to bird conservation group BirdLife International.


Birds exhibit thuggish mafia-like behvaior as nest enforcers
(3/5/2007) Parasitic birds engage in mafia-like reprisals to encourage host acceptance of their eggs according to researchers writing in the online early edition of PNAS.


African penguin population drops 40% - cause unknown
(3/2/2007) African penguin populations have fallen by 40 percent in the past few years according to an article published in the March 2, 2006 issue of Science. Biologists are puzzled by the decline.


Why do birds migrate? Seasonal food scarcity finds study
(3/1/2007) A new paper attempts to argue the age old question of why birds migrate. The authors, Dr. Alice Boyle and Dr. Courtney J. Conway of the University of Arizona, argue that birds are driven to fly long distances due to seasonal food scarcity.


The Scoop on Penguins - Feathered Fish or Bodacious Bird?
(2/28/2007) Penguins are birds that can toboggan on ice using their webbed feet to propel them. The fastest penguin, the gentoo, can swim about 15 miles per hour, faster than long-distance runners. Penguins can also dive very deep, some to depths of about 1,750 feet. They use their wings (which are really like flippers) to propel themselves in the water. It looks as if they are "flying" underwater, something they cannot do in the air.


Biologists record call of rare Sumatran ground cuckoo for first time
(2/26/2007) A team of biologists with the New York-based Wildlife conservation Society (WCS) have recorded for the first time the call of the extremely rare Sumatran ground cuckoo, found only on the island of Sumatra in Indonesia.


Balloon technology could cut cost of solar energy 90% by 2010
(2/21/2007) With high energy prices and mounting concerns over human-induced climate change, there is intense interest in renewable energy, especially solar, which produces no pollution and is readily available in the form of sunlight. In recent years, however, the solar energy market has been hampered by supply shortages of refined silicon, the critical resource needed for solar cell fabrication. Further, because solar installations traditionally require a large surface area to capture as much sunlight as possible, solar arrays often take up real estate, occupying land used agricultural production and other purposes. Without government subsidies, solar is not presently viable in many areas.


Birds plan for the future
(2/21/2007) New research suggests that some birds plan for the future. Previously it was believed that planning was exclusively a human activity. Writing in the current edition of the journal Nature, scientists at Cambridge Univeristy found that western scrub-jays plan for future food shortages by storing food. Unlike squirrels and other animals that store foods during lean times as a matter of habit, the researchers show that the birds actually learn from their previous experiences of food scarcity, saving food for future consumption when they anticipate future periods of famine.


Photo of 4-legged duck found in Britain
(2/18/2007) A 4-legged duckling has turned up in Britain according to a report from the Associated Press. Pictures of the animal were released Saturday.


15 'new' bird species revealed in North America
(2/18/2007) DNA testing has revealed 15 'new' species of birds in North America and six 'new' species of bats from the South American country of Guyana, according to a paper appearing in the British journal Molecular Ecology Notes.


Robots aid in search for Ivory-billed woodpecker
(2/17/2007) Scientists have installed robotic cameras to help in the search of the world's most elusive bird, the Ivory-billed woodpecker.


Rare giant bat eats night-flying birds
(2/13/2007) A new study published in PLoS ONE, an open online journal, reports that nocturnally migrating songbirds are preyed upon by giant bats. The findings go against the belief that night-flying birds lacked predators.


Rare vulture colony found in Cambodia
(2/6/2007) Working in the remote forests of Cambodia, conservationists from the Wildlife conservation Society (WCS) have just discovered Southeast Asia's only known breeding colony of slender-billed vultures, one of the world's most threatened bird species.


13% of Florida's whooping cranes killed in weekend storms
(2/5/2007) 17 whooping cranes were killed in severe storms in Florida according to a report from the Associated Press. The whooping crane, the tallest bird in North America, is one of North America's most endangered birds with a wild population of less than 360. Until the recent storms, Florida was home to a non-migratory population of 53 and a migratory population of 83, according to the Whooping Crane conservation Association.


'Happy Feet' penguins declining fast in the Falklands
(12/22/2006) The rockhopper penguin, a species featured in the movie Happy Feet, has taken a suffered a 30 percent population decline over the past five years according to the latest survey figures from Falklands conservation, a conservation group with offices in Stanley, Falkland Islands and London, England.


City life causes song birds to change their tune
(12/4/2006) Cities cause birds to change their songs according to research published in the December 5th issue of the journal Current Biology. Hans Slabbekoorn and Ardie den Boer-Visser, biologists from Leiden University in the Netherlands, studied songs of the great tit (Parus major), a species that has successfully adapted to urban life, in ten major European cities, and compared them to songs of great tits living in nearby forest areas. They found that urban songs were shorter and faster-paced than the forest songs, and tended to be higher frequency to overcome the low-frequency environmental noise, such as traffic noise, associated with cities.


Migratory species threatened by global warming
(11/19/2006) Urgent action is need to prevent extinction of migratory species due to global warming says a new report from the United Nations Environment Programme (UNEP).


Global warming could doom many bird species
(11/13/2006) Up to 72 percent of bird species in northeastern Australia and more than a third in Europe could go extinct unless action is taken to address global warming said a report from environmental group WWF. The report, "Bird Species and Climate Change: The Global Status Report", reviews more than 200 scientific articles on birds and identifies groups of birds at high risk from climate change: migratory, mountain, island, wetland, Arctic, Antarctic and seabirds. It says that species that can easily migrate to new habitats will likely thrive, while birds that live in niche environments may decline.


Cambodia sets aside land for endangered bird
(11/6/2006) Cambodia has set aside more than one hundred square miles of habitat for the Bengal florican, a large grassland bird that is endangered due to habitat loss, according to the Wildlife conservation Society (WCS).


Pet trade and habitat loss decimating wild macaw populations
(10/23/2006) Macaws, the world's largest parrots, are declining in the wild due to over-zealous collecting for the pet trade, poaching, and habitat loss according to a researcher at Texas A&M University. Dr. Don Brightsmith, a bird specialist at Texas A&M University's Schubot Exotic Bird Center, says that of the world's 17 species of macaws, one is extinct, another is extinct in the wild, and seven are endangered. All are suffering population declines in the wild.


Common wood duck and laughing gull could transmit bird flu in America
(10/23/2006) The common wood duck and laughing gull are very susceptible to H5N1 avian influenza viruses (bird flu) and have the potential to transmit them according to scientists at the University of Georgia. Their research, published in the November issue of the journal Emerging Infectious Diseases, shows that different species birds respond differently to bird flu viruses.


Photo of new bird species discovered in Colombia
(10/10/2006) A bird species new to science has been discovered on a remote mountain range in northern Colombia according to conservation International. The Yariguies Brush-Finch (Atlapetes latinuchus yariguierum), a large and colorful finch with black, yellow and red plumage, is described in the June issue of the scientific journal Bulletin of the British Ornithologists Club.

(10/5/2006) A bird species new to science has been discovered on a remote mountain range in northern Colombia according to conservation International.


Albatrosses at risk due to fishing
(10/3/2006) About 1 percent of world's waved albatrosses were killed by fisherman in a one-year period according to a new study published online Sept. 26 in the journal Biological conservation


Not extinct? Ivory-billed Woodpecker may live in Florida
(9/26/2006) Researchers found evidence of the Ivory-billed Woodpecker, a bird once believed to be extinct, in a remote river basin in the panhandle of Florida. The discovery, announced in Avian conservation and Ecology, was made in May 2005 by a research team led by Auburn University professor Geoff Hill. The bird was sighted on the Choctawhatchee River and though the team captured no photographs of the species.


DDT linked to smaller brains in birds
(7/14/2006) For the first time researchers have found evidence that natural exposure to a contaminant damages the brain of a wild animal. Scientists at the University of Alberta discovered that the regions in robins' brains responsible for singing and mating shrink when exposed to high levels of DDT. The new study, published in the current issue of Behavioural Brain Research, suggests that exposure to environmental levels of DDT can cause significant changes in the brains of songbirds.


Birds Face Extinction Risk Due To Human Activities
(7/5/2006) Human activities have caused some 500 bird species worldwide to go extinct over the past five millennia, and 21st-century extinction rates likely will accelerate to approximately 10 additional species per year unless societies take action to reverse the trend, according to a new report. Without the influence of humans, the expected extinction rate for birds would be roughly one species per century.


1250 bird species may be extinct by 2100
(7/4/2006) Two new studies paint a mixed future for the world's bird populations, one suggesting that 12 percent of existing species could be extinct by 2100 and the other finding shifts in migration patterns among birds that migrate long distances. Researchers at Stanford University, Duke University and the Missouri Botanical Garden in St. Louis examined the extinction record for birds and found that scientists have likely underestimated the number of extinctions.


Avian Flu Threat to Biological Diversity
(3/23/2006) A far wider range of species including rare and endangered ones may be affected by highly virulent avian flu than has previously been supposed. Experts attending the Convention on Biological Diversity (CBD) conference say there is growing evidence that the H5N1 virus can infect and harm big cats like leopards and tigers, small cats such as civets and other mammals like martens, weasels, badgers and otters.


Good-looking birds more immune against bird flu
(3/20/2006) A research team at Uppsala University, Sweden has shown in a new study, published in the journal Acta Zoologica, that the size of the spot on a male collared flycatcher's forehead reflects how well the immune defence system combats viruses such as avian influenza. The white spot is also attractive to female birds searching for a mate.


Pictures of new species discovered in New Guinea
(2/7/2006) A team of scientists led by conservation International (CI) found dozens of new species in a survey of New Guinea's Foja Mountains. The December 2005 trip by a team of U.S., Indonesian, and Australian scientists discovered new species of frogs, butterflies, plants, and an orange-faced honeyeater, the first new bird from the island of New Guinea in more than 60 years.


Redheads top the pecking order by flaunting it
(12/30/2005) Red-headed finches dominate their black-headed and yellow-headed peers by physical aggression and by the mere fact of being red-headed, according to research published in the Proceedings of the Royal Society. University of New South Wales biologists made the discovery following experiments with stunningly colourful Gouldian finches (Erythrura gouldiae). Among Australia's most endangered native birds, Gouldian finches are now restricted to small isolated populations across the tropical north.


Making wind power less deadly for birds
(12/15/2005) High oil prices and concern over climate change are driving interest in renewable energy technologies. All types of potential power sources -- not limited to the sun, ocean tides and waves, raw sewage, and even insects -- are the focus of media reports, while governments and industry scramble to announce their grand plans for adopting green energy.


Toucan Beaks Are Models Of Lightweight Strength says UCSD engineer
(11/30/2005) As a boy growing up in Brazil 40 years ago, Marc A. Meyers marveled at the lightweight toughness of toucan beaks that he occasionally found on the forest floor. Now a materials scientist and professor of mechanical and aerospace engineering at UCSD's Jacobs School of Engineering, Meyers said makers of airplanes and automobiles may benefit from the first ever detailed engineering analysis of toucan beaks conducted in his lab.
