Black-capped Vireo are listed as Endangered by the U.S. Fish and Wildlife Service, and are on the 2014 State of the Birds Watch List, which lists bird species that are at risk of becoming threatened or endangered without conservation action. The IUCN Red List lists them as Vulnerable. Partners in Flight estimates a global breeding population of 24,000, with 45% breeding in the U.S., and 100% spending some part of the year in Mexico. They are a U.S.-Canada Stewardship species and a Tri-national Concern species, and rate an 18 out of 20 on the Continental Concern Score. These birds are largely extirpated from their traditional breeding range in the United States. Cowbird parasitism is a major threat; cowbird removal efforts have evidently led to local increases in Black-capped Vireo populations. Destruction of suitable habitat through urban and suburban development and livestock grazing also have significantly contributed to the species' decline. Habitat maintenance and creation through prescribed burning and other manipulation are a high management priority.Back to top
