Gray-fronted Quail-Dove
Geotrygon caniceps
A multicolored chunky dove of dense, wet forests with thick leaf-litter. It is most often found on the ground, sometimes in association with Blue-headed or Ruddy Quail-Doves. Walks with an unusual posture with chest down, head forward, and tail up. Its unstriped head, pale gray forehead, and largely iridescent body eliminate other species within range. Song is upslurred repeated “cooo-oop,” sometimes preceded by “oo-oo-oo-oo-oo.”
识别特征
The male grey-fronted quail-dove is 26 to 30 cm (10 to 12 in) long and the female 27 cm (11 in). They weigh 192 to 210 g (6.8 to 7.4 oz). The adult male's forehead ("front") is grayish white darkening to gray on the rest of the head, with slight purplish iridescence on the back of it. The medium gray throat darkens on the breast, whose sides are gossy purple. The belly is cream and the vent area rufous. The shoulders are glossy purple, the lower back and rump bluish purple, and the tail gray. The adult female is very similar but duller. Juveniles have a brownish gray forehead, pale gray throat, dark brown upperparts, and chestnut underparts.
分类信息
The grey-fronted quail-dove and most of what are now the other species in genus Geotrygon were previously in genus Oreopeleia. In addition, it was considered conspecific with what is now the white-fronted quail-dove (Geotrygon leucometopia) under the name "grey-headed quail-dove". Though the taxonomies of the North American Classification Committee of the American Ornithological Society (AOS), the International Ornithological Committee (IOC), and Clements use the English name "grey-fronted quail-dove" for the current G. caniceps, the Handbook of the Birds of the World retains the pre-split "grey-headed quail-dove" name for it.<p>The grey-fronted quail-dove is monotypic.

分布与栖息地
The grey-fronted quail-dove was formerly found throughout Cuba but is now apparently limited to the island's eastern margin and the Sierra del Rosario in the west. It favors wet primary and secondary forests in the lowlands and at elevations up to 1,200 m (3,900 ft).

行为
The grey-fronted quail-dove forages on the ground, singly or in pairs, where it feeds on seeds and small invertebrates.<p>The grey-fronted quail-dove's breeding season spans at least from Jan to August. It builds a nest of twigs and leaves lined with rootlets and grass and places it 1 to 3 m (3.3 to 9.8 ft) above ground, typically in a bush surrounded by tall grass. The clutch size is one or two.<p>The grey-fronted quail-dove's song is a "long series of short, low-pitched 'haoo' or 'cooo' notes" that can be given slowly or very fast. It sings year round though less in the wet season.

Ochre-lored Flatbill
Tolmomyias flaviventris
Small, yellowish-olive flycatcher that ranges mainly in northern and eastern South America as well eastern Panama. Distinguishing features include its yellow throat and breast, orange face, thick wingbars, and wide bill. Similar to Olive-faced Flycatcher, which used to be considered the same species and called Yellow-breasted Flycatcher. Note their different ranges, which mostly do not overlap. Ochre-lored Flycatcher has a brighter face with a hint of orange, more distinct wingbars, and has a different voice. Its most common call is a piercing whistle given alone or in a slow series. Occasionally also gives well-spaced rasping calls. Inhabits secondary forest and light woodland, usually avoiding the interior of mature forest.
Sharp-billed Canastero
Asthenes pyrrholeuca
Fairly common but easily overlooked in the Andes and southern lowlands, mainly in drier habitats with low scrubby bushes. Usually rather skulking; keeps low in bushes and creeps in vegetation, but often sings from atop a bush. Plumage rather plain brownish overall, suggesting a House Wren, but note very long, loosely held tail with rusty sides. Compare with Cordilleran Canastero of more open habitats and also note distinctive voices.
Aldabra Drongo
Dicrurus aldabranus
Bold, black fork-tailed bird with a red eye. There is sometimes but not always a tuft of long feathers above the bill. Juveniles have an unusual pale-gray plumage, but still show the forked tail. Found in all habitats with bushes and trees on the remote Seychelles island of Aldabra, including forest, mangroves, and thick scrub. Perches prominently in the open, swooping out to catch insects on the wing. Often follows Madagascar Coucals and Aldabra Giant Tortoises, feeding on insects that they disturb. Song is a repeated sequence of whistles, creaks, and rasps.
