Birds have accents, too: Researchers find cultural change in the dialects of parrots over 22-year period
While distinct languages and dialects are common to human societies, most people are unaware that other species may similarly have culturally significant dialects. New research conducted by a team of researchers from the University of Pittsburgh at J.....»»
Surprising mechanism for removing dead cells identified
Billions of our cells die every day to make way for the growth of new ones. Most of these goners are cleaned up by phagocytes—mobile immune cells that migrate where needed to engulf problematic substances. But some dying or dead cells are consumed.....»»
Paleontologists discover new predatory dinosaur with a distinctive "eyebrow"
Theropod dinosaurs are one of the most important large groups of dinosaurs, including well-known predators, such as Tyrannosaurus and Allosaurus, as well as modern birds. A variety of theropods are known from the Mesozoic Era, the age of the dinosaur.....»»

Exposure to bacteria in landfill sites and polluted rivers may explain prevalence among city-dwelling birds......»»
Rural migration tied to land use and climate change need more attention, scientists say
Climate and other environmental changes sometimes drive people to migrate, especially if the land no longer supports a population's way of life. In turn, mobile populations alter the environment in which they settle......»»
City birds found to be carriers of antimicrobial resistant bacteria
Research led by scientists at the Ineos Oxford Institute for antimicrobial research at Oxford University has found that wild birds such as ducks and crows living close to humans, for example in cities, are likely to carry bacteria with antimicrobial.....»»
Research shows that glossy black-cockatoos prefer to feed from trees growing in acidic soils
Glossy black-cockatoos are seed-eating birds that feed almost exclusively on the cones of drooping sheoak trees. However, counter-intuitively, they select trees that grow on the poorest soils found on ancient sedimentary rocks......»»
How feeding birds may be polluting local environments
