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.
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.
