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 habitat of this species is forests and more open woodland. A nesting hole is excavated in large dead trees. The entrance is fairly large, about 45 to 50 cm (17.5 to 19.5 in) in diameter, and oval-shaped. Female lays 2 to 3 white eggs, sometimes four. Incubation lasts about 9 to 14 days, by both sexes. Woodpeckers have short incubation period, but at contrary, nesting period is longer than in other birds’ species. Chicks are brooded and fed by both parents, and remain at nest for 3 to 4 weeks after hatching. Young remain within the family group until next breeding season.
