The crimson-crested Woodpecker (Campephilus melanoleucos) is a very large woodpecker which is a resident breeding bird from Panama south to northern border regions of Argentina, and on Trinidad. The crimson-crested woodpecker is all black above, has a red crest and has white lines running down the sides of the black throat and shoulders, which meet in a V on the back. The underparts are white, heavily barred with black. They show white on the wings in flight. Crimson-crested woodpeckers chip out holes, often quite large, while searching out insects in trees. They mainly eat wood-boring insects and larvae, as well as ants, termites, small vertebrates and caterpillars. The animal matter is sometimes supplemented with berries.
