Woodpeckers are a large family of climbing birds comprising 216 species. Fourteen woodpecker species occur in Canada (10 in Ontario).
Woodpeckers rarely perch. They are primarily arboreal, although some species such as the northern flicker spend much of their life on the ground. Most species are nonmigratory; however, many found in Canada migrate. Their flight is strong, rapid and undulating.
Woodpeckers are heavy bodied and have moderately long, rather rounded wings, and round or wedge-shaped tails. The chisel-shaped bill is strong and usually straight. Nostrils are hidden under tufts of bristlelike feathers. These birds vary in length from 8-60 cm. Plumage can contain black, white, yellow, red, brown or green, in various combinations, and they often have red or yellow on the head. Many species are barred, spotted or streaked, especially on underparts; several have a prominent crest.
Usually, legs are short and strong with 2 toes in front and 2 behind. The toes have strong, sharp, downward-curving nails, allowing the birds to cling to vertical tree trunks or to undersides of branches. Stiffened, pointed tail feathers provide support when the birds climb up and down trees.
Woodpeckers have a loud voice and a variety of call notes. They also drum with the bill, particularly during nesting season and when they have found a particularly resonant surface.

Woodpeckers have super long tongues. Their tongues are usually about twice the length of their bill so that they can reach for insects inside the holes they peck out. When not in use, the long tongue curls around the back of the head between the skull and the skin.
