Andrew Farnsworth, a researcher at Cornell University's Lab of Ornithology, told The New York Times more than 300 sightings have been recorded in a year.

The study by King’s researchers suggests that predatory birds in urban spaces are vulnerable to changes in human activities that support prey populations.

A bald eagle has laid two eggs this month in a Southern California nest and nature lovers will watch for the hatchings via an online live feed. Mother eagle Jackie delivered the second egg Saturday afternoon amid a snowstorm near the mountain community of Big Bear east of Los Angeles. The first egg came Jan. 11.

More than 140 million birds have died and hundreds of millions of pounds have been spent in the past year in the US, UK and EU in tackling bird flu, as some experts said continual culling was “morally” wrong. With an international agreement on the use of vaccinations likely to be one or two years away, the situation will probably worsen this winter as outbreaks of bird flu continue to rise.

"If it works...it’s a sea change event."

A successful expedition in Papua New Guinea captured photos and video of the chicken-size pigeon, highlighting the value of local ecological knowledge as scientists seek out other long-missing species.

A growing body of research suggests human behavior on social media is strikingly similar to collective behavior in nature.

A tiny rufous hummingbird was released safely in Vancouver late last month after it was found flying around Prince George, more than 500 kilometres north, long after it should have migrated for the winter. The bird first caught the notice of Clive Keen, an editor with B.C. Birding magazine, when his wife Susan pointed it out in early October.

Craig Woods was once a fitter-and-turner, but eight years ago he gave it away for a life of hard yakka under the open sky, setting up a chemical-free raspberry farm where he and wife Melissa grow most of their own food and run on solar power and tank water. He also brought home a brood of emu chicks. After a lifelong fascination with Australia's native ratite, Mr Woods wanted to raise the emus as outdoor pets.

Although it still feels like beach weather across much of North America, billions of birds have started taking wing for one of nature’s great spectacles: fall migration. Birds fly south from the northern U.S. and Canada to wintering grounds in the southern U.S., Caribbean and Latin America, sometimes covering thousands of miles. Other birds leave temperate Eurasia for Africa, tropical Asia or Australia.

The rush to build wind farms to combat climate change is colliding with preservation of one of the U.S. West’s most spectacular predators — the golden eagle — as the species teeters on the edge of decline.

CODY, Wyo. (AP) — The rush to build wind farms to combat climate change is colliding with preservation of one of the U.S. West’s most spectacular predators — the golden eagle — as the species teeters on the edge of decline.

Conservationists have called for ministers to ban the release of millions of gamebirds to prevent the UK’s wild birds being wiped out by a “catastrophic” avian flu epidemic this winter. The Royal Society for the Protection of Birds (RSPB) said there was a significant risk that pheasants, partridge and ducks released for shooting from 1 October could spread avian influenza into wild bird populations, wreaking havoc in farmland and garden birds.

Latest figures show native birds have increased by 51 percent on Wellington's Miramar Peninsula. This includes a whopping 550 percent rise in the pīwakawaka / fantail population of, a 275 percent increase in riroriro / grey warblers, and a 49 percent increase in tūī.

A pair of bald eagles near Nanaimo, B.C., have adopted a baby red-tailed hawk and are raising it alongside their own eaglet. But while the hawk is now part of the eagles’ family, it could have just as easily been their dinner.
