Second year males may be intermediate in colouration between adult males and females.
Breeds in USA (Oklahoma, Texas) and northern Mexico (Coahuila, Nuevo Leon, and Tamaulipas). Extirpated from Kansas.
Winters in lowlands along the Pacific coast of Mexico, south west from the breeding area.
This is a monotypic species.
The Black-capped Vireo is listed as an Endangered species by the U.S. Fish and Wildlife Service. Brown-headed Cowbird parasitism is a major problem.
Scrublands with scattered clumps of shrubs, especially thornscrub, separated by open grassland.
Both sexes build the nest laying 3-4 eggs which are incubated for 14-17 days. The female broods the young, with the male providing the food. The young fledge after 10 to 12 days
These birds can produce more than one clutch in the breeding season. The male tends some or all of the fledglings, while the female re-nests (this may be with another male).
The diet includes beetles and caterpillars.
