The New Caledonian Crow (Corvus moneduloides) is a moderately sized crow (40 cm in length) similar in size to the House Crow but less slender looking. The bird is all black with a rich gloss to the feathers of purple, dark blue and some green in good light. The bill, feet and legs are all black too. The bill is of moderate size but is unusual in that the tip of the lower is angled up making it somewhat chisel-like in profile.

It is one of a small group of animals now accepted in scientific study to be not only a tool-user, but a tool-maker. The New Caledonian Crow is also the only non-human species currently known to spontaneously make tools out of materials it does not encounter in the wild. It takes a very wide range of food items including many types of insects and other invertebrates (some caught in flight with some agility, including night-flying insects which it catches at dusk), eggs and nestlings, snails (which it drops from a height onto hard stones), and various nuts and seeds. Most interestingly, it is known for its manufacture of plant material into hooks or barbs for extracting grubs from inside logs and branches. It is one of the most remarkable and resourceful of creatures, showing great ingenuity in the search for food.


The nest is built high in a tree with usually only 2 eggs laid from September to November.


The voice is described as a soft waa-waa or wak-wak, sometimes a hoarse waaaaw.

Tool-Using Crows Give New Meaning to Term `Bird Brained' (1205 words)
While tool use among birds is not unheard of, Hunt's New Caledonian crows, close kin to American crows, were observed employing two distinctly different kinds of tools to forage for invertebrates such as insects, centipedes, and larvae.
Hunt's report suggests that the tool-making and tool-using behavior of crows rivals that of Homo erectus, although the issues, Boesch notes, "are not straightforward." He argues that chimpanzees have shown a level of tool manufacture and use comparable to that described by Hunt.
Hunt's observations on the New Caledonian crows are not sufficient to determine whether the tool manufacture and use is transmitted genetically, culturally, or a combination thereof, she noted.
