Curtin University researchers studying one of the oldest collections of ancient animal bones in the world have used DNA still present in the bones to identify 17 animal species, including two rodents previously not known to be in the collection.

Bolivian environmental authorities on Sunday announced an investigation into the apparent poisoning of 35 Andean condors in a rural community, one of the most devastating such cases for the endangered species.

Lainy Day, an associate professor of biology at the University of Mississippi and director of the university's neuroscience minor, has published an article in Nature, an international journal that publishes the finest peer-reviewed research in all fields of science and technology.

Humans, wildlife, and the environment are all interconnected and play a role in one another's health and well-being. Sentinel species, such as birds, are good indicators of environmental health, and they can send subtle warning signs that humans may be in danger next.

UCC palaeontologists have discovered new evidence that the fate of vertebrate animals over the last 400 million years has been shaped by microscopic melanin pigments.

The rapid spread of COVID-19 in 2020 disrupted field research and environmental monitoring efforts worldwide. Travel restrictions and social distancing forced scientists to cancel studies or pause their work for months. These limits measurably reduced the accuracy of weather forecasts and created data gaps on issues ranging from bird migration to civil rights in U.S. public schools.

New research published today in the journal Scientific Reports based on the largest analysis to date of commercial data on egg-laying hen mortality finds that mortality in higher-welfare, cage-free housing systems decreases over time as management experience increases and knowledge accrues.

A team of researchers from, Lund University, the University of Stellenbosch and the Western Cape Department of Agriculture for South Africa has learned more about how animals cope with rising temperatures by studying ostriches living in South Africa. In their paper published in the journal Nature Communications, the group describes studying multiple attributes of reproduction in ostriches over a 20-year-period, and what they learned about them and their ability to adapt to climate change.

One of birdwatching's most commonly held and colorfully named beliefs, the Patagonia Picnic Table Effect, is more a fun myth than a true phenomenon, Oregon State University research suggests.

Birds play an underrecognized role in spreading tickborne disease due to their capacity for long-distance travel and tendency to split their time in different parts of the world—patterns that are shifting due to climate change. Knowing which bird species are able to infect ticks with pathogens can help scientists predict where tickborne diseases might emerge and pose a health risk to people.

3-D printing is a universal process in the sense that pretty much any part that can be drawn up in a CAD program can be printed, at least within a certain resolution. Machining a part on a mill or lathe, while having the advantage of greater accuracy and material options, is a slightly less universal process in that many possible designs that exist in theory could never be machined. A hollow sphere can easily be printed, but a ball could never be milled as a single part into a hollow sphere—unless you happen to have a milling machine tiny enough to fit inside the ball. But what about biological parts, and whole animals? How universal, from a design perspective, is growth?

Harpy eagles are considered by many to be among the planet's most spectacular birds. They are also among its most elusive, generally avoiding areas disturbed by human activity—therefore already having vanished from portions of its range—and listed by the International Union for the Conservation of Nature (IUCN) as being 'Near-Threatened'.

Scientists have shown where bird species would exist in the absence of human activity under research that could provide a new approach to setting conservation priorities.

On January 5, 2021, the day before the world watched in horror as the U.S. Capitol was assaulted, the Trump administration laid siege to the Migratory Bird Treaty Act. The revision is a major blow to conservation efforts, lifting penalties for industries that accidentally cause harm to birds protected under the act.

New research led by BirdLife International, the University of East Anglia (UEA) and British Antarctic Survey highlights how a proposed network of marine protected areas could help safeguard some of the most important areas at sea for breeding Antarctic penguins.

Young Seychelles warblers fare better if their elderly parents have help raising them, according to new research from the University of East Anglia (UEA) and the University of Groningen.
-
Habitat destruction by logging and agriculture is pushing parrot species towards extinction, while current protected areas are failing to mitigate these effects, according to new research.

For most people, the word "vampire" brings to mind Dracula or perhaps slayers such as Blade or Buffy; or maybe even the vampire bats of South America. Few will think of a small and rather lovely bird—the finch.

Millions of birds travel between their breeding and wintering grounds during spring and autumn migration, creating one of the greatest spectacles of the natural world. These journeys often span incredible distances. For example, the Blackpoll Warbler, which weighs less than half an ounce, may travel up to 1,500 miles between its nesting grounds in Canada and its wintering grounds in the Caribbean and South America.

Have you ever seen magpies play-fighting with one another, or rolling around in high spirits? Or an apostlebird running at full speed with a stick in its beak, chased by a troop of other apostlebirds? Well, such play behavior may be associated with a larger brain and a longer life.

In a normal year, biologists Daniel Janzen and Winnie Hallwachs spend about six months in Costa Rica, where they conduct research and pursue conservation efforts in Área de Conservación Guanacaste (ACG), a World Heritage Site in the northwest that encompasses, a network of parks and preserves they helped establish in the 1980s and that has grown to more than 400,000 acres, including marine, dry forest, cloud forest, and rain forest environments.

Foraging humans find food, reproduce, share parenting, and even organize their social groups in similar ways as surrounding mammal and bird species, depending on where they live in the world, new research has found.
-
The Interior Department said it will eliminate from federal protection more than 3 million acres in California, Oregon and Washington vital to the northern spotted owl, a species considered endangered under federal law.

A racing pigeon has survived an extraordinary 13,000-kilometer (8,000-mile) Pacific Ocean crossing from the United States to find a new home in Australia. Now authorities consider the bird a quarantine risk and plan to kill it.
Man-made borders threaten wildlife as climate changes

Walls and fences designed to secure national borders could make it difficult for almost 700 mammal species to adapt to climate change, according to new research.
