The strong downwards curve from the tip of this beak suggests that it ripped the flesh from the body of other animals; many extant bird species with this feature are carnivorous. CT scans performed on the skull of a phorusrhacid reveal that the species would not have been able to shake its prey side to side, but rather exert significant ...
Other avivore mammals who occasionally prey on birds include most carnivora; a number of primates ranging from lorises and night monkeys over baboons and chimpanzees to humans; orcas; opossums and other marsupials; rats and other rodents; hedgehogs and other insectivora and bats. A number of mammal species are specialized predators of birds.
A new study by biologists from the Scripps Research Institute shows that a bird flu virus is just a single mutation away from having human-ready receptors. If the H5N1 virus does make the switch ...
The spread of the H5N1 bird flu virus among dairy cows has worried health experts, who say it increases the risk of the virus becoming a greater threat to humans. (Tomas Ovalle / For The Times)
Today, many species face habitat loss and other threats caused by humans; bird conservation groups work to protect birds and to influence governments to do so. Birds have appeared in the mythologies and religions of many cultures since ancient Sumer.
The first severe case of bird flu in the U.S. is showing signs of mutation, stoking fears that the virus could become more transmissible among humans, the U.S. Centers for Disease Control and ...

Human activity threatens about 1,200 bird species with extinction, though efforts are underway to protect them. Recreational birdwatching is an important part of the ecotourism industry.
