Dusky-capped Woodcreeper

Identificazione

The dusky-capped woodcreeper weighs about 22 to 28 g (0.78 to 0.99 oz). It is a smallish, slim, woodcreeper with a slim decurved bill. The sexes have the same plumage. Adults' crown and nape are grayish brown becoming warm brown on the back. Their wings, uppertail coverts, rump, and tail are brown with a rufous tinge. Their chin and throat are whitish to buffy-white. Their underparts are brown with blackish-edged whitish streaks. Their underwing coverts are rufous-brown. Their iris is dark brown, their bill pale brown with a pinkish tinge and a darker tip on the mandible, and the legs and feet usually blackish slate or grayish. Juveniles are similar to adults with the largest difference being their shorter, straighter, and yellowish bill.

Tassonomia

Until the 2010s what is now the dusky-capped woodcreeper was considered a subspecies of Lepidocolaptes albolineatus, which was then called the lineated woodcreeper. Starting at that time all but the lineated's nominate subspecies were split from it, eventually resulting in the dusky-capped woodcreeper, the Duida woodcreeper (L. duidae), the Inambari woodcreeper (L. fatimalimae), and a monotypic L. albolineatus which was renamed the Guianan woodcreeper. In the initial split, two subspecies of the lineated woodcreeper, L. a. fuscicapillus and L. a. layardi, were each accorded species status as the "Rondonia" and "Layard's" woodcreepers respectively. In 2020 the two were lumped as the two subspecies of the current dusky-capped woodcreeper.
