According to Nature, the New Caledonian crow (Corvus Moneduloides) makes tools and uses them to access food in challenging to get to places. The ‘Alalã’ (C. Hawaiiensis; Hawaiian crow), which is extinct in the wild since 2000 and only survives in captivity, has also demonstrated similar tool-using abilities.

Researchers drilled horizontal and vertical holes in logs, and the bird was able to pick tools of the right dimensions with its beak and extract prey placed in the crevices. The bird makes the bill-held tools from sticks, and the birds were able to use them without prior training skillfully.
