The gray vireo (Vireo vicinior) is a small North American passerine bird. It breeds from the southwestern United States and northern Baja California to western Texas. It is a migrant, wintering in northwestern Mexico, in western Sonora state, and the southern Baja Peninsula in Baja California Sur; it remains all year only in Big Bend National Park in southwest Texas. It is usually found at altitudes between Шаблон:Convert in its Mexican breeding grounds. This vireo frequents dry brush, especially juniper, on the slopes of the southwestern mountains.[1]

Description

The gray vireo is Шаблон:Convert in length, gray above, and dull white below, with a single faint wing bar and an eye-ring. It has a short, thick bill. Sexes are similar. The sideways twitching of its tail is unique among vireos and is reminiscent of that of gnatcatchers. The song is hu-wee, chu-wee, che-weet, chee, ch-churr-weet, churr, schray.

Behavior

The gray vireo has skulking habits and is difficult to observe in the dense vegetation it inhabits which is mostly pinyon-juniper woodland or scrub oak woodland. It feeds mainly on insects, and birds that overwinter in Mexico additionally consume fruit. Nests are built within Шаблон:Convert of the ground, often in a thorny tree and consist of dry grasses, plant remains, shreds of bark and spider's web, lined with grasses and fine fibres. A clutch of three or four white eggs is laid and incubated by both parents for about thirteen days. The young leave the nest a fortnight later. Attempted parasitism by the brown-headed cowbird (Molothrus ater) often causes the nest to be abandoned.[1]
