Birds — like anteaters, baleen whales and turtles — don't have teeth. But this wasn't always the case. The common ancestor of all living birds sported a set of pearly whites 116 million years ago, a new study finds.
The world's largest ibis, and one of the world's most endangered birds, has received some good news. A giant ibis (Thaumatibis giganteawas) has been photographed in the Kampong Som Valley in Koh Kong Province in Cambodia, the first record from this province in nearly a hundred years. Adults can grow to reach nearly 3.5 feet (106 centimeters) long.
Old World fruit bats, also known as the flying foxes or megabats, are members of the family Pteropodidae, which contains 41 genera and about 170 species. These bats are restricted to the Old World in a tropical and subtropical distribution, ranging no further than the eastern Mediterranean and South Asia, and are absent from northwest Africa, southwest Australia, a majority of the Palearctic region, and all of the Western Hemisphere.
In search of the origin of bat echolocation, Dr Yossi Yovel of Tel Aviv University and his colleagues studied how Old World fruit bats, long classified as non-echolocating, orient in darkness.
They selected a total of 19 wild individuals representing three fruit bat species to find that all of them used click-based echo sensing.
“We did all we could to prove it wrong, including sealing the bats’ mouths and anesthetizing their tongues, but nothing stopped them from clicking, except for when we interfered with their wing flaps.”
New Caledonian crows—well known for their impressive stick-wielding abilities—show preferences when it comes to holding their tools on the left or the right sides of their beaks, in much the same way that people are left- or right-handed.
When Benjamin the pygmy goat was born, his mother was unable to wean both him and his twin. In his fragile state, he found a rescuer in Tom Horsfield… Tom took in the baby goat and has dedicated himself to raising him over the last month.
Imitation can be obnoxious. For those with siblings, imitating your brother's or sister's every word was a surefire way to steadily drive them toward insanity. Annoying it may be, imitation is also special; it's a behavior long regarded to be uniquely human. The skill of imitation is a little less exclusive now, as reptiles join the ranks of creatures capable of the social feat. Researchers from the United Kingdom and Austria recently demonstrated that one lizard, the bearded dragon (Pogona vitt
In the first case of its kind, a New York appeals court rejected on Thursday an animal rights advocate’s bid to extend “legal personhood” to chimpanzees, saying the primates are incapable of bearing the responsibilities that come with having legal...
In a discovery that overturns conventional wisdom about bats, researchers reporting in the Cell Press journal Current Biology on December 4 have found that Old World fruit bats—long classified as "non-echolocating"—actually do use a rudimentary...
Birds learn new foraging techniques by observing others in their social network, 'copycat' behaviour that can sustain foraging 'traditions' that last years, according to a study of how innovations spread and persist in wild great tits (Parus major).
