Black-capped Vireo

Basic Description

The smallest vireo that occurs regularly in the United States, the Black-capped Vireo lives in low scrublands of Oklahoma, Texas, and northern Mexico. Habitat changes and nest parasitism by Brown-headed Cowbirds caused the Black-capped Vireo to vanish across much of the northern part of its historic range, leading to listing as a federally endangered species in 1987. Thanks to intensive efforts, the vireo rebounded and was removed from the Endangered Species List in 2018.
