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.

分布与栖息地
The dove is a resident breeder from southernmost Texas in the United States through Mexico and Central America south to western Peru and central Argentina. It also breeds on the offshore islands of northern South America, including Trinidad and Tobago and the Netherlands Antilles. It inhabits scrub, woodland and forest.<p>The following subspecies are recognized:<p>The subspecies chlorauchenia was formerly known as chalcauchenia, but the former name was found to have precedence in 2023.

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.

Eastern Nicator
Nicator gularis
Unusual bushshrike-like bird with a heavy hooked bill. The underparts are pale, and the upperparts are olive-green with bold white spotting. The yellow corners of the tail can be conspicuous in flight. Found in forest, thickets, and dense woodland. Skulking and secretive, usually remaining inside of tangles in the understory and midstory. Very vocal, and most often detected by voice: a quick jumble of wooden notes. Range does not overlap with other nicators.
Ash-throated Crake
Mustelirallus albicollis
Common but often overlooked in a variety of wetland areas including freshwater marshes, rice fields, and damp grasslands. Sometimes encountered crossing dirt roads and trails. Mostly brown above and gray below, but dark centers on the back feathers give it a streaked look. The song is very loud: a long rolling “purrl”.
Collared Inca
Coeligena torquata
This large, flashy hummingbird is a common resident throughout much of the Andes, where it inhabits lush cloud forest and frequently visits feeders. Note the white breast patch and long, straight bill. The white tail markings really stand out when it flares its tail, which it often does when interacting with other hummers around feeders. Male is darker than female, sometimes almost black, which makes his colorful crown patch more evident. Birds found south of central Peru and north of the Colombia-Venezuela border region are now considered to be separate species, Gould’s Inca and Green Inca respectively.
