About These Birds
Downy Woodpecker
The downy woodpecker is the smallest and most widespread woodpecker in North America. Its small size allows it to forage on thin branches and weed stems that larger woodpeckers cannot access. Downies often join mixed-species flocks in winter, benefiting from the extra vigilance of multiple species watching for predators.
Black-backed Woodpecker
The Black-backed Woodpecker is a medium-sized woodpecker of boreal conifer forests across North America, particularly specialist of recently burned forests. It has entirely black upperparts, white underparts with barring on the sides, and males have a yellow crown patch. It forages by flaking bark from dead trees to extract wood-boring beetle larvae that colonize burned timber.
