Alaska’s Shorebirds Exposed to Mercury

Shorebirds breeding in Alaska are being exposed to mercury at levels that could put their populations at risk, according to new research from The Condor: Ornithological Applications. Thanks to atmospheric circulation and other factors, the mercury that we deposit into the environment tends to accumulate in the Arctic. Mercury exposure can reduce birds’ reproductive success and […]

Fatal Beak Disorder Spreading Among Birds

Scientists have uncovered a fascinating new clue in the global mystery surrounding wild birds with grossly deformed beaks. A team of researchers from the California Academy of Sciences, University of California San Francisco (UCSF), and the U.S. Geological Survey (USGS) have identified a novel virus that has been linked to Avian Keratin Disorder (AKD), a […]

Chemical Pollution Gets to Antarctic Marine Bird Colonies

Latitude is the main factor which determines the organic pollutant concentration in Antarctic giant petrels -emblematic species in the Antarctic and sub-Antarctic regions-, according to an article from the journal Environmental Research in which Professor Jacob González Solís, from the Department of Evolutionary Biology, Ecology and Environmental Sciences and the Biodiversity Research Institute of the University of […]

Habitat Needs of Nestling, Fledgling Songbirds

Both before and after they leave the nest, baby birds face a host of challenges. A new study in The Condor: Ornithological Applications examining songbird survival in the nestling and fledgling stages finds that even in the same habitat, different species face different risks and survive at different rates. Read More…

Individual Quality Trumps Reproductive Tradeoffs in Ducks

Not all ducks are created equal. In female Wood Ducks, variation in individual quality is what matters for breeding success and survival, according to the results of a new long-term study being published in The Auk: Ornithological Advances. Drawing on 11 years of data on almost 500 ducks, Robert Kennamer of the University of Georgia’s Savannah […]

Research Reveals Trend in Bird-Shape Evolution on Islands

In groundbreaking new work, Natalie Wright, a postdoctoral fellow at the University of Montana, has discovered a predictable trend in the evolution of bird shape. Her research showing that birds on islands have evolved toward flightlessness was published April 11, 2016 in Proceedings of the National Academy of Sciences. Her partners include Christopher Witt of the […]

Storks Fill Up on Junk Food

White storks are addicted to junk food and make round-trips of almost 100km to get their fix — according to new research from the University of East Anglia. In folklore, storks would carry babies to parents around the world. But since the mid 1980s, increasing numbers no longer migrate from Europe to Africa for the […]

Migratory Birds Disperse Seeds Long Distances

Some species of plants are capable of colonising new habitats thanks to birds that transport their seeds in their plumage or digestive tract. Until recently it was known that birds could do this over short distances, but a new study shows that they are also capable of dispersing them over more than 300 kilometres. Read […]
