White-tipped Dove
Leptotila verreauxi
Plump, pale, ground-dwelling dove with pink legs. Widespread and common throughout Middle and South America, from Texas to Argentina. Namesake white tips on outer tail feathers more extensive than other closely related species. Paler than other relatives such as Gray-chested or Gray-headed Doves, especially on the neck and belly, with less contrasting gray or rufous tones. Found in a variety of wooded habitats; more likely to be found in disturbed or scrubby areas than congeners, but also occurs within mature forest. Occasionally visits bird feeders, but otherwise shy and difficult to see well. Listen for low cooing song, starting with a short introductory hoot followed by a longer hollow note.
识别特征
The dove is about 28 cm (11 in) long and weighs 155 g (5.5 oz). Adult birds of most races have a grey tinge from the crown to the nape, a pale grey or whitish forehead and a whitish throat. The eye-ring is typically red in most of its range, but blue in most of the Amazon and northern South America. The upperparts and wings are grey-brown, and the underparts are whitish shading to pinkish, dull grey or buff on the chest. The underwing coverts are rufous. The tail is broadly tipped with white, but this is best visible from below or in flight. The bill is black, the legs are red and the iris is yellow.<p>The white-tipped dove resembles the closely related grey-fronted dove (Leptotila rufaxilla), which prefers humid forest habitats. The best distinctions are the greyer forehead and crown, which contrast less with the hindcrown than in the grey-fronted dove. In the area of overlap, the white-tipped dove usually has a blue (not red) eye-ring, but this is not reliable in some parts of Brazil, Argentina, Bolivia, Paraguay and Uruguay, where it typically is red in both species.

行为
The white-tipped dove is usually seen alone or in pairs, and is rather wary. They remain in their territory and do not migrate. Its flight is fast and direct, with the regular beats and clattering of the wings, characteristic of pigeons in general. They live in a variety of woodland habitats. The call is a deep hollow ooo-wooooo.<p>It builds a large stick nest in a tree near ground level and lays two white eggs. Incubation is about 14 days, and fledging another 15.<p>The food is mainly seeds obtained by foraging on the ground, but it will also take insects, including butterflies and moths.<p>They utilize their voice to perform a variety of tasks: defend territory, attract potential mates, indicate food resources, alert predators, and maintain group contact.<p>Two notes at the same pitch is their signature call: an introductory hoot followed by a longer, more audible, hollow note.

A small, sharp-billed warbler-like bird. Note the olive-green back, the yellow underparts with broad olive flanks, and the very broad white spectacles around the eyes. Found in the highlands of central Kenya, in montane forest, forest edge, exotic tree plantations, and lush gardens and scrub. Usually in hyperactive pairs or flocks.
