Mercury exposure is related to a 10 percent decrease in nest survival in two tidal marsh songbird species surveyed in four states, from Maine to New Jersey, according to a new University of Maine-led study. These species have been experiencing sharp declines in this region due to sea level rise-related habitat loss and, therefore, mercury may exacerbate known climate change-driven population declines.

A team of researchers from Deakin University in Australia and Clemson University in the U.S. has found that female finches change the song they sing to their eggs when temperatures rise. This results in hatchling mitochondria producing more ATP and less heat. In their paper published in Proceedings of the Royal Society B, the group describes experiments they conducted with captive zebra finches.

Using satellite data and hundreds of thousands of crowd-sourced field observations, scientists have developed a more precise method for mapping the locations of habitats critical for the survival of more than 1,300 Central and South American forest bird species at high risk of extinction.

Penguins may not require passports to travel, but they do need protection, according to an international research team who analyzed 131 scientific papers on penguin movement at sea. The work comes as the United Nations continues to negotiate a treaty regarding the sustainable use of areas beyond national jurisdiction, the high seas over which no coastal state can claim ownership.

Migratory birds are specially adapted to find their way over extreme distances that represent remarkable tests of endurance. Now, researchers reporting December 6 in the journal Current Biology have discovered an unexpected way that migratory birds keep their cool during such arduous journeys: lighter-colored feathers.

An international study led by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) and the Department of Animal Health and Anatomy of the UAB shows that knowledge of Amazonian inhabitants can be a game changer in assessing animal population trends in a context of urgent need for conservation strategies and limited financial resources.

For birders struggling to figure out what kind of Redpoll they're watching, new research from the University of Colorado Boulder says don't worry—the different species are actually all one and the same.

Efforts to sequence the genomes of the world's animals tend to focus on those that most resemble humans with the work conducted almost entirely in the Global North, according to an analysis led by Washington State University.

A joint study by researchers from the Xinjiang Institute of Ecology and Geography (XIEG) of the Chinese Academy of Sciences and Eurasian Bustard Alliance has found that anthropogenic disturbance is the main factor affecting the habitat quality of the great bustard population in Western China.

A team of researchers at the Memorial University of Newfoundland has found that the ring-billed gull is able to pass a widely used cognitive test called the string-pull test. They describe their results in a paper published in the journal Royal Society Open Science.

Not all relationships end in "happily ever after," and birds are no exception. While more than 90% of bird species form monogamous couples, many of these will end in divorce.

The warming of the planet is taking a deadly toll on seabirds that are suffering population declines from starvation, inability to reproduce, heat waves and extreme weather.

An analysis by Oak Ridge National Laboratory showed that using less-profitable farmland to grow bioenergy crops such as switchgrass could fuel not only clean energy, but also gains in biodiversity.

Fossils found in Chile are from a strange-looking dog-sized dinosaur species that had a unique slashing tail weapon, scientists reported Wednesday.

New Zealand's extinct Haast's eagle (Hieraaetus moorei), the largest known eagle, gulped down viscera like a vulture and may even have been bald, new research suggests.

Pelecanimimus polyodon from the Lower Cretaceous (125 Ma) is the first predatory dinosaur found in Spain. An international team of paleontologists have now discovered features on the fossil that are typical of birds and dinosaurs closely related to birds. The researchers have published their findings in the Zoological Journal of the Linnean Society.

Up to 216 Australian birds are now threatened—compared with 195 a decade ago—and climate change is now the main driver pushing threatened birds closer to extinction, landmark new research has found.

They are the faunal emblem of the Australian Capital Territory, but enthusiasm for the gang-gang cockatoo stretches far beyond the Canberra bubble.

An oil sheen spotted off Huntington Beach last weekend served as a potent reminder of how long it will take Southern California to untangle the legal, regulatory and environmental fallout of an October pipeline spill that released an estimated 25,000 gallons of crude into the ocean.

Imagine going to hear your favorite orchestral piece played in a world-class venue—and only the woodwind and brass sections turning up. Whether we're aware of it or not, this sparse soundscape is similar to what we're often experiencing when we head out to our favorite parks or nature reserves. The sounds produced by the natural world are changing, which means that the benefits we gain from being in nature are likely to be changing too.
