Identificación

The white-throated woodpecker is about 19 to 20 cm (7.5 to 7.9 in) long and weighs about 69 g (2.4 oz). Males and females have the same plumage except on their heads. Males are red from forehead to hindneck and very widely on the malar (cheek); the latter has a wide yellow stripe above it.The female has red only on the nape but is otherwise the same as the male. Adults of both sexes have the eponymous white chin and throat. Their upperparts are bronze-green. Their flight feathers are mostly dark brown with pale cinnamon-rufous on the inner webs. Their tail is blackish with greenish edges on the feathers. Their upper breast is yellowish green; the feathers have pale centers and dark tips. The rest of their underparts are white with olive barring. Their shortish beak is blackish to gray, their iris dark brown to red-brown, and the legs dark olive to blackish. Juveniles are greener than adults and males have red only from the rear crown to the hindneck.

Taxonomía

The white-throated woodpecker was originally described as Picus leucolaemus. Since its inclusion in Piculus it has at times been considered conspecific with the rufous-winged woodpecker (P. simplex), the stripe-cheeked woodpecker (P. callopterus), and the Lita woodpecker (P. litae); the four may form a superspecies. It and just the Lita woodpecker have also been treated as conspecific. The white-throated woodpecker is monotypic.
