Taxonomy
This is a monotypic species[1].
Status
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.
Habitat
Scrublands with scattered clumps of shrubs, especially thornscrub, separated by open grassland.
Behaviour
Breeding
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).
Diet
The diet includes beetles and caterpillars.
