Guianan Warbling Antbird

Overview

The Guianan warbling antbird, also known as the Guianan antwarbler, is an insectivorous bird belonging to the family Thamnophilidae. It is a small forest bird found across the Guiana region and parts of Venezuela and Brazil.

Identification

• Length of 11 to 12 cm with a weight of 10 to 14 g.
• Adult males feature a black crown with a white central streak and supercilium, an olive-grey back with a white interscapular patch, and rufous rump and flanks.
• Females resemble males in pattern but possess paler colours, with a buff-streaked crown and olive-brown wing coverts.
• Male song consists of 7–10 clear notes that accelerate and shift in pitch before becoming abruptly raspy, while females respond with descending notes.

Habitat

Inhabits the edges of terra firme and várzea evergreen forest, transition zones, and mature secondary woodland, often along watercourses or at gaps created by fallen trees. Found in Venezuela, the Guianas, and northeastern Brazil at elevations up to 1,200 m in Venezuela and 1,300 m in Guyana.

Diet

Primarily feeds on insects and spiders, foraging mostly between the ground and 6 m above, though occasionally reaching 12 m. Typically hunts in dense vegetation such as vine tangles, understorey shrubs, and bamboo thickets by lunging from perches, making short sallies, or probing dead leaf clusters.
