Pileated woodpeckers are mainly black with a red crest, and have a white line down the sides of the throat. Younger specimens tend to have less curved crests, or "mohawks" as some refer to them. They show white on the wings in flight. The flight of these birds is strong and direct, but undulates in the way characteristic of woodpeckers.
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 woodpeckers except the related American and Eurasian three-toed woodpeckers, this species has ...
The closely related pileated and white-bellied woodpeckers also broadly overlap in size with the black woodpecker, but both are somewhat smaller in average and maximal size and mass. [7] The plumage of this crow-sized woodpecker is entirely black apart from a red crown.
The ladder-backed woodpecker is a small woodpecker about 16.5 to 19 cm (6½ to 7½ inches) in length. It is primarily colored black and white, with a barred pattern on its back and wings resembling the rungs of a ladder. Its rump is speckled with black, as are its cream-colored underparts on the breast and flanks.
Nuttall's woodpecker has black wings and tail feathers with white barring. On the ventral surface, colour is white with black spots and barring. It has a black forehead with white streaks on the sides and an unbarred black region at the top of the back. Adult males have a distinguishable red crown which females do not.
They have black wings with large white patches. The female is completely different in appearance: mainly black, with a pale yellow breast, a brownish head with black streaking and fine barring on the back, breast and sides. Originally, the female was considered to be a different species and named the black-breasted woodpecker by Cassin ...
An adult great spotted woodpecker is 20–24 cm (7.9–9.4 in) long, weighs 70–98 g (2.5–3.5 oz) and has a 34–39 cm (13–15 in) wingspan. [6] [10] The upperparts are glossy blue-black, with white on the sides of the face and neck. Black lines run from the shoulder to the nape, the base of the bill and about halfway across the breast.
With an average weight of 339 g (12.0 oz) in males and 291 g (10.3 oz) in females, it is perhaps the heaviest certainly extant woodpecker in the Americas. [5] [6] This species is mainly pure black, with a white wing patch and a grey, chisel-like beak. Males have a crimson head and crest.
