Hairy Woodpecker -BOG


Hairy Woodpecker / P. villosus

Order:Piciformes Family:Picidae Genus:Picoides

General Characteristics:
-The plumage of Hairy Woodpeckers is a mix of black and white.
Its wings, lower back, and tail are black with white spots; its upper back and outer tail feathers are white. Its underside is white, and its head is marked with wide alternating black and white stripes. Males have a red spot at the backs of their heads which females lack.
-
-Hairy Woodpeckers forage primarily on the trunks or main limbs of trees, where they probe into crevices and scale off bark searching for prey. They drum frequently in spring.
-They feed on bark-boring and wood-boring beetle larvae in dead and dying trees are the main food of Hairy Woodpeckers. They also feed on sap from sapsucker holes, berries, nuts, seeds, and suet.

Special Adaptations:
-While Hairy Woodpeckers are still widespread and common throughout their range, their populations in many areas have probably declined from historic levels. Forestry practices that remove snags and large trees have reduced nesting and roosting areas, and the introduced European Starlings and House Sparrows compete for nesting and roosting sites.
