From Wikipedia
The Ivory-billed Woodpecker is one of the largest woodpecker species in the world. The largest is the closely related Imperial Woodpecker (C. imperialis) of western Mexico, another rare species which is very likely to be extinct. The Ivory-billed measures from 48 to 53 cm (19 to 21 in) in length and 450 to 570 g (1.0 to 1.25 lb) in weight, with short legs and feet ending in large, curved claws.
