» Life History

Habitat Requirements

Bell's Vireo habitat includes dense, low, shrubby vegetation, generally early successional stages in riparian areas, brushy fields, young second-growth forest or woodland, scrub oak, coastal chaparral, and mesquite brushlands, often near water in arid regions. Bell's Vireo nests are open bag-like or basket-like cups of grass, straw-like stems, plant fibers, small skeletonized leaves, paper, and strips of bark fastened with spider silk; lined almost invariably with fine, brown or yellow grass stems. The outside of nests are decorated with spider egg cases and suspended from forks of low branches of small trees or shrubs.

Food Habits

The Bell's Vireo hops between branches while foraging, and mainly feeds on insects and spiders.

Movement / Home Range

Bell's Vireos breed in central and southwestern U.S. while wintering on the southern tip of Baja California Sur and along the Pacific edge of Central America. When fall migration takes place, Bell's Vireos will leave the northernmost limits of their breeding range in August and September, and then migrate through central Mexico.

Other

Degradation of habitat is a primary threat for the Bell's Vireo. Land use patterns along riparian habitat strongly influences abundance in breeding range. Bell's Vireo populations are currently declining throughout its range. For more information about this species in Minnesota, refer to the following resource: <li>Audubon Minnesota. 2014.
