Brett Smith for redOrbit.com - Your Universe Online In a well-known Aesop’s fable, a crow comes across a pitcher with a small, out-of-reach amount of water in the bottom. To get a drink, the crow drops stones in the pitcher until the water level rises enough for the bird to reach it with its beak. While the point to the fable may be to teach the virtue of ingenuity, a team of scientists from New Zealand and the United Kingdom wanted to see if New Caledonian crows understood the idea...

The new study, published today in Biology Letters, shows that jackdaw eyes are used as a warning signal to successfully deter...

The Jungle Crow is highly inconsistent in both its overall size (46-59 cm in length) and body proportions across the large geographical region that it covers. In the far northeast in Japan, the Kuriles and the Sakhalin peninsula, it is somewhat larger than the Carrion Crow, while the form from India in the southwest of its range is significantly smaller. All forms have a relatively long bill with the upper one quite thick and arched, making it look heavy and almost Raven-like. As a general...
