Woodpeckers

Woodpeckers are birds in the family Picidae, which includes about 200 species of true woodpeckers, wrynecks, as well as the diminutive piculets. Woodpeckers are widespread in the world's forested areas, occurring everywhere but Australia, New Zealand, New Guinea, Madagascar, and Antarctica. Birds in the woodpecker family range in size from the relatively enormous imperial woodpecker (Campephilus imperialis) of Mexico, with a body length of 21.7 in (55 cm) and weight of 1.1 lb (550 g), to tropical piculets only 3.2 in (8 cm) long.
