White-eyed Vireo

Measurements:

Length: 4.3–5.1 in (11–13 cm) Weight: 0.3–0.5 oz (10–14 g) Wingspan: 6.7 in (17 cm) Its head and back are a greyish olive, and the underparts are white with yellow flanks. The wings and tail are dark, and there are two white wing bars on each wing. The eyes have white irises, and are surrounded by yellow spectacles. Sexes are similar.

It breeds in the eastern United States from New England west to northern Missouri and south to Texas and Florida, and also in eastern Mexico, northern Central America, Cuba and the Bahamas. Populations on the US Gulf Coast and further south are resident, but most North American birds migrate south in winter. This vireo frequents bushes and shrubs in abandoned cultivation or overgrown pastures.

During the breeding season, the diet of this species consists almost exclusively of insects, primarily caterpillars and stink bugs (Pentatomidae); beetles, flies, wasps, snails, and very rarely small vertebrates are also consumed. In the autumn and winter it supplements its diet of insects with berries.
