The black-backed woodpecker (Picoides arcticus), also known as the Arctic three-toed woodpecker, is a medium-sized woodpecker (23 cm (9.1 in) long) inhabiting the forests of North America. Taxonomy [ edit ]
The black-rumped flameback is the only golden-backed woodpecker with both a black throat and a black rump. [8] Leucistic birds have been recorded. [13] Two specimens of male birds from the northern Western Ghats have been noted to have red-tipped feathers on the malar region almost forming a malar stripe.
Additionally, the common flameback shares a unique morphological feature with two other woodpeckers, this being the highly developed protractor pterygoidei muscle, which is also present in the olive-backed woodpecker and surprisingly, the maroon woodpecker (Blythipicus rubiginosus). [6]
The foot of all three species show an extreme adaptation to arboreal living by lacking the first digit, or hallux. It has been pointed out however that various species of pied woodpecker are similar in having a short first digit. [8] Two species of woodpecker in genus Sasia (not closely related) also lack the first digit.
Exceptions are the black-backed woodpecker and the American and Eurasian three-toed woodpeckers, which have only three toes on each foot. The tails of all woodpeckers, except the piculets and wrynecks, are stiffened, and when the bird perches on a vertical surface, the tail and feet work together to support it. [4]

The tongue of the woodpecker is long and ends in a barb. With its tongue the woodpecker skewers the grub and draws it out of the trunk. Woodpeckers also use their beaks to create larger holes for their nests which are 15–45 cm (6–18 inches) below the opening. These nests are lined only with wood chips and hold 2–8 white eggs.
Until recently, it was considered to be the same species as the Eurasian three-toed woodpecker, P. tridactylus. [4] Adults are black on the head, wings and rump, and white from the throat to the belly; the flanks are white with black bars. The back is white with black bars and the tail is black with the white outer feathers barred with black.
