Red-stained Woodpecker

Identificazione

The red-stained woodpecker is about 15 to 18 cm (5.9 to 7.1 in) long and weighs 32 to 44 g (1.1 to 1.6 oz). Males and females have the same plumage except on their heads. Males of the nominate subspecies affinis have a red crown with black feather bases that show through. The female has a dark olive-brown crown. Adults of both sexes have a mostly buffish face with olive streaks and a golden-yellow nape and hindneck. Their upperparts are mostly yellowish green with some red feather tips, pale yellow streaks, and some barring on the rump and uppertail coverts. Their flight feathers are dark brown with wide green edges and buffish white bars on the primaries and secondaries. Their tail is dark brown with yellowish bars on most feathers. Their underparts are light cinnamon-buff with dark olive-brown bars that are more widely spaced on the belly and flanks. The iris is brown to red-brown, the longish beak blackish with a paler mandible, and the legs are olive green to green-gray. Juveniles resemble adults with a darker and streakier face; both sexes have some red on the crown, the male more than the female.<p>Subspecies orenocensis has greener upperparts with less red than the nominate. Subspecies hilaris is larger than the nominate, with more bronzy or yellow upperparts with fainter streaks, and with broad red tips on the wing coverts. Subspecies ruficeps is the same size as hilaris, with larger red tips on the cover feathers and more obvious yellow streaks on the upperparts.

Tassonomia

The International Ornithological Committee and BirdLife International's Handbook of the Birds of the World place the red-stained woodpecker in genus Veniliornis. However, starting in 2018, the American Ornithological Society and the Clements taxonomy moved all species of genus Veniliornis into genus Dryobates.<p>The taxonomic systems agree that the red-stained woodpecker has these four subspecies:<p>Subspecies hilaris and ruficeps have at times been treated as separate species. What is now the Choco woodpecker (V. (or D.) chocoensis) was at one time treated as a subspecies of the red-stained woodpecker.

Areale e habitat

The subspecies of red-stained woodpecker are found thus:<p>The red-stained woodpecker primarily inhabits the interior of tall rainforest. It occurs less at the forest edges, in secondary forest, and scrublands. In Ecuador and Peru it also occurs in humid lowland terra firme and sometimes várzea forests. It will occasionally forage in more open landscapes. In elevation it occurs between 100 and 500 m (300 and 1,600 ft) in Venezuela, up to 1,000 m (3,300 ft) in Colombia, as high as 850 m (2,800 ft) but usually only to 600 m (2,000 ft) in Ecuador, and up to 1,300 m (4,300 ft) in Peru.
