CONSERVATION STATUS

Near Threatened

The Bell's Vireo has a breeding range of around 291,000 square kilometers. This includes dense, low, brushy habitats in the central and southwestern United States south to central Mexico. It winters in similar habitats in western Mexico south to El Salvador. Populations of the Bell's Vireo have shown large declines over several decades because of widespread conversion of required second growth habitat to urban and agricultural developments. The species has an estimated breeding population of 4,600,000, and a conservation rating of Near Threatened.

INTERESTING FACTS

  • Bell's Vireos have become less common in areas where the riparian vegetation has been reduced.
  • If cowbird eggs are deposited in a nest prior to vireo egg-laying, nests are usually abandoned. If vireo eggs are removed by cowbirds, the nest may also be abandoned.
  • The subspecies found in California, the Least Bell's Vireo, is endangered.
  • A group of bell's vireos are collectively known as a "peal" and a "tintinabulation" of vireos.
