Common Yellowthroat

Overview

The common yellowthroat, Geothlypis trichas, is a New World warbler and an abundant breeder across North America, ranging from southern Canada to central Mexico. It is classified as Least Concern on the IUCN Red List despite a historical decline in numbers due to habitat loss.

Identification

• Small songbird measuring 11–13 cm in length, featuring olive backs, wings, and tails.
• Bright yellow throat and chest with a white belly; adult males possess a distinctive black face mask bordered above with white or gray, while females lack this mask and have paler underparts.
• Produces a loud song described as 'twichety twichety twichety twich' and a soft call of 'jip'.

Habitat

These birds breed in marshes and other wet areas with low, dense vegetation, though they may also inhabit areas with dense shrubs or, less commonly, dry areas. In the northern parts of its range, the species is migratory, wintering in Central America and the West Indies, while southern forms are largely resident.

Diet

Common yellowthroats feed on insects, which are typically captured in dense vegetation but are sometimes caught in midair.

Did you know?

Although common yellowthroat nests are commonly subject to brood parasitism by the brown-headed cowbird, females appear to prefer mating with males that have larger black facial masks.
