Vireo griseus
Conservation status | Northern edge of range varies over time: for example, disappeared from Massachusetts and then re-invaded; spread into Michigan in 1960s. Surveys indicate slight declines over much of range since 1960s. |
---|---|
Family | Vireos |
Habitat | Wood edges, brush, brambles, undergrowth. Breeds in various kinds of dense low growth, including briar tangles on low swampy ground, shrubby thickets of maple, wild plum, willow, and other saplings in overgrown pastures, and scrub in open woods or near forest edges. Winters in a wide array of similar habitats. |
Forages by moving actively among twigs and branches in dense low cover, searching for insects among the foliage. Often hovers momentarily to take insects from leaves.
4, sometimes 3-5. White with specks of brown or black. Incubation is by both parents, 13-15 days. Nests are commonly parasitized by cowbirds. Young: Both parents feed the nestlings. Young leave the nest about 9-11 days after hatching. 1 brood per year in the north, 2 in the south.

Insects and berries. In the breeding season, takes almost entirely insects, and nearly one-third of diet then may be caterpillars, moths, and butterflies. Diet also includes true bugs, scale insects, many kinds of beetles, ants, wasps, bees, grasshoppers; also spiders, snails, and occasionally small lizards. In migration and in winter, also eats berries and small fruits.
Male sings incessantly from early spring to late summer to defend nesting territory. In courtship, male displays to female by fluffing plumage, spreading tail, and uttering a whining call. Nest: Placed low (within 25' of ground, usually much lower) in shrub or sapling. Nest is supported by the rim woven onto a horizontal forked twig. Both parents help build nest, a deep, hanging cup made of twigs, roots, shreds of bark, grass stems, leaves, plant down, lichen, moss, sometimes fragments of wasp nests. Nest is bound with spiderwebs, lined with fine grass and fibers.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.
