Here is a close up of an adult male Downy Woodpecker. The active little Downy Woodpecker is a familiar sight at backyard feeders and in parks and woodlots, where it joins flocks of chickadees and nuthatches, barely outsizing them. The Downy is the smallest woodpecker in North America and their breeding habitat is usally forested areas mainly deciduous which makes Caledon, Ontario a good home for them. They nest in a tree cavity excavated by the nesting pair in a dead tree or limb. Downy Woodpeckers forage on trees, picking the bark surface in summer and digging deeper in winter. They mainly eat insects, also seeds and berries. In winter, especially, Downy Woodpeckers can often be found in treed suburban backyards and will feed on suet at birdfeeders.
