Grey-throated Warbler

Overview

The grey-throated warbler (Myiothlypis cinereicollis) is a species of New World warbler in the family Parulidae, native to Colombia and Venezuela. It is a sedentary resident that primarily inhabits humid premontane forests and is currently listed as Least Concern by the IUCN.

Identification

• Approximately 14 cm (5.5 in) long with identical plumage in both sexes.
• Mostly medium gray head featuring a bright yellow crown stripe with dark gray borders and a thin blackish eye-line.
• Pale gray throat and breast, with olive green upperparts, wings, and tail, and yellow lower underparts.
• Blackish brown bill, yellowish pink legs, and dark iris.

Habitat

Found in the Serranía del Perijá and the Venezuelan and Colombian Andes, where it primarily inhabits the edges and interior of humid premontane forest as well as undisturbed secondary forest understories. Elevation ranges vary by location, spanning from 600 to 2,100 m.

Diet

The species usually forages in the forest understory, remaining in cover, and sometimes joins mixed-species feeding flocks in Colombia, though this behaviour is apparently absent in Venezuela. However, its specific diet has not been studied.

Did you know?

Despite being a warbler, the species is not highly vocal; its song is described as weak and easily overlooked, consisting of 3-6 high-pitched wispy notes such as 'sa see-see-sa-SEE!'. The one known nest found so far was shaped like an oven on a steep earthen bank, constructed from bark fibers, twigs, and vines.
