Black-backed Woodpecker
Picoides arcticus
The plumage of adults is black on the head, back, wings and rump. They are white from the throat to the belly; the flanks are white with black bars. Their tail is black with white outer feathers. There is an element of sexual dimorphism in the plumage, with the adult male possessing a yellow cap. Unlike all other true woodpeckers except the related American and Eurasian three-toed woodpeckers, this species has three-toed feet. Measurements: Length: 9.1 inches (23 cm) Weight: 2.1–3.1 oz (60–88 g) Wingspan: 15.8–16.5 in (40–42 cm) Voice: The call note of the black-backed woodpecker is a single, sharp pik, and is lower pitched than the call of the American three-toed woodpecker.
