About These Birds
Acorn Woodpecker
The Acorn Woodpecker is a highly social woodpecker weighing about 79g of western North American oak woodland. It stores thousands of acorns in specially drilled 'granary trees' shared by the group.
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.
