Altamira Yellowthroats

The Altamira Yellowthroats (Geothlypis flavovelata) are endemic to the Gulf slope of northeastern Mexico, where they are usually seen in pairs and don’t usually associate with other species. Their numbers have been declining due to loss of habitat.

This species is closely related to Common Yellowthroat, Belding’s Yellowthroat and Bahama Yellowthroat, with which it forms a superspecies, and has been considered conspecific (of, or belonging to, the same species) with those species.


The Altamira Yellowthroat measures 13 cm in length (including the tail) and has a yellow-green back and bright yellow belly. The adult male has a black facemask and yellow crown. Females are similar, but lack the black mask and have an olive crown.

Similar Species:

This species is easily distinguished from wintering Common Yellowthroats by its uniform yellow underparts, in contrast to Common’s white belly. Males’ yellow forehead bands are diagnostic.

Breeding / Nesting:

The breed in coastal marshes and lagoons, usually with cattails. They build cup nests low in vegetation.

Call / Vocalization:

Its song is described as a loud wichety wichety wichety wich, and the call is a soft jip. The vocalizations are very similar to those of Common Yellowthroat.

Diet / Feeding

They moslty feed on insects usually captured in dense vegetation.
