Ladder-backed Woodpecker

About the Ladder-backed Woodpecker

The ladder-backed woodpecker (Dryobates scalaris) is a North American woodpecker. The ladder-backed woodpecker is a small woodpecker about 16.5 to 19 cm (6½ to 7½ inches) in length. It is primarily colored black and white, with a barred pattern on its back and wings resembling the rungs of a ladder. Its rump is speckled with black, as are its cream-colored underparts on the breast and flanks. Southern populations have duskier buff breasts and distinctly smaller bills. Adult males have a red crown patch that is smaller in immatures and lacking in adult females. The ladder-backed woodpecker is very similar in appearance to Nuttall's woodpecker, but has much less black on its head and upper back, and the range of the two species only intersects a minimal amount in southern California and northern Baja California. Hybrids are known.

Ladder-backed woodpeckers nest in cavities excavated from tree trunks, or in more arid environments a large cactus will do. The female lays between 2 and 7 eggs, which are plain white. The eggs are incubated by both sexes, but the nesting period and other details are unknown.
