Just took this shot this "icy" sunday afternoon, this female Hairy Woodpecker (no red spot on head) was enjoying some lunch on a dead gray birch tree out our window. So cool and will have to work on switching to the better zoom lense and catch him in the act again. Some sizeable fresh holes on the tree.

Hairy woodpecker Picoides villosus
Identification Tips:
Length: 7.5 inches
Medium-sized black and white woodpecker
Fairly long bill
Mostly black head set off by broad white supercilium and lower border to auriculars
Black nape
White back
Black wings with white spotting on coverts and flight feathers
White underparts
Black rump
Black tail with white outer tail feathers
Significant racial variation can result in juveniles with barred outer tail feathers (Queen Charlotte Islands), juveniles with barred backs and flanks (Maritime provinces) and birds with brown feathering replacing the black (Pacific Northwest).
Adult male: Red spot at rear of head
Similar species: Other black and white woodpeckers such as Ladder-backed, Strickland's, Red-cockaded and Nuttall's have shorter bills, barred backs, and patterning on the chests. Black-backed woodpecker is easily distinguished by the darker face, black back, and barred flanks. Three-toed Woodpecker is best distinguished by the darker face and barred flanks, since some races can have white backs. In the Maritimes juvenile Hairy Woodpeckers can more closely resemble Three-toed Woodpeckers and it is best to concentrate on differences in facial pattern and bill size when identifying birds in this area.
Similarly, juvenile Hairy Woodpeckers on the Queen Charlotte Islands can have barred outer tail feathers and such birds should be carefully separated from Downy Woodpeckers by their larger size and larger bills. Downy Woodpecker is most similar, and differs only in its smaller size, proportionally smaller bill, barred outer tail feathers, and different call.
