Brainy ravens

8 January 2000

A naturalist and gifted writer who has spent 15 years observing both captive
and wild ravens reports on their hunting, socialising, mating and other skills,
all in the interest of determining whether these very clever birds have what
humans deem intelligence. They lie, they play, and, Bernd Heinrich says in
The Mind of a Raven, they think. Published by Cliff Street Books,
£7.99, ISBN 0060930632.

Archaeopteryx. Artwork of the prehistoric feathered reptile Archaeopteryx which lived around 150 million years ago. Discovered in 1861 in southern Germany, it was the first feathered fossil specimen ever found. Despite possessing bird-like feathers, wings and a wishbone, Archaeopteryx also had sharp teeth, finger digits and a bony tail similar to non-bird predatory dinosaurs. This species and numerous other feathered fossils support the theory that modern day birds evolved from prehistoric theropod dinosaurs.
