Black-backed woodpecker
The black-backed woodpecker was described and illustrated by the English naturalist William Swainson in 1832 from a specimen collected near the source of the Athabasca River on the eastern slopes of the Rocky Mountains in Alberta, Canada.[3] The black-backed woodpecker is now placed in the genus Picoides which was erected by the French naturalist Bernard Germain de Lacépède in 1799.There is an element of sexual dimorphism in the plumage, with the adult male possessing a yellow cap.Measurements:[6] Their breeding range is boreal forest across Canada, Alaska, the Northwestern United States, as well as northern Wisconsin,[7] the Adirondacks in New York, New England, Minnesota,[8] and Upper Michigan.Black-backed woodpeckers are generally non-migratory but historically have undertaken intermittent irruptions.
