Orange-breasted Bunting
Passerina leclancherii
Beautiful small bunting of lowlands and foothills; endemic to west Mexico. Occurs in brushy woodland and edge, adjacent weedy fields, and open grassy areas. Often in small groups, feeding on roadside grasses and flushing up with brilliant blue flashes. Also feeds at all levels in fruiting trees and bushes. Male unmistakable: electric turquoise blue and green above; rich yellow below with a burnished orange breast. Female duller overall: greenish above and yellow below, with a bluish tail. Female brighter yellowish below than slightly larger female Painted Bunting.
识别特征
The orange-breasted bunting grows to a length of about 12.5 cm (5 in) and is slightly smaller than the rose-bellied bunting (Passerina rositae), which shares its range. The adult male has a pale green crown, turquoise blue nape and upper parts, often tinged with green, and a turquoise tail. The lores, eye-ring and underparts are canary yellow, deepening to golden-orange on the breast. The adult female has greyish-green upper parts and yellow underparts. The iris is dark brown, and the beak and legs are grey. The song is a rather plaintive warble, rather slower and less drawn out than that of other members of the genus.

分布与栖息地
The orange-breasted bunting is endemic to Mexico. Its range extends from the Pacific coast in southern Nayarit, Jalisco, Michoacán and Guerrero to western Chiapas, and inland to the western part of Puebla, an area of about 276,000 km2 (107,000 sq mi). It inhabits tropical dry forest and arid scrubland, thorny thickets, bushy deciduous woodland, clearings and woodland edges, at altitudes up to about 900 m (3,000 ft). It has a patchy distribution, not being present in some areas of apparently suitable habitat. It is more abundant in secondary growth than in undisturbed forest. The species was introduced to the Hawaiian island of Oahu in 1941 but did not become established, and was extirpated by 1952.

行为
The birds form small groups when foraging or may forage in pairs. The diet of this species has not been studied, but in general, buntings in this genus are seed-eaters, with some fruit and invertebrates being eaten. Birds in captivity will consume white millet, hemp seed and thistle seed, as well as hard sweet apples, ant cocoons and mealworms. Breeding takes place in the wet season in May and June. The nest is a cup-shaped structure formed of rootlets, grasses and dry leaves, with a softer lining and is built in a low bush or thick scrub. A clutch of three or four bluish-white or greenish-white eggs are laid.

Sao Tome Paradise-Flycatcher
Terpsiphone atrochalybeia
A distinctive long-tailed paradise-flycatcher with different-looking sexes. Male is glossy blue-black with a pale blue bill and blue eye-rings; female has a dark crown, a gray face, rusty upperparts, and pale underparts. Juvenile is like female; young male slowly turns black. A common resident throughout São Tomé in the understory and at middle levels of most habitats. The only other flycatcher within its range is the dull brown Spotted Flycatcher, a scarce migrant. Calls include a rapid electric clicking and buzzing “dzzrt-dzzrt-dzzrt.” The song is a musical repeated “swee dzee-tee che-ree.”
Elgon Francolin
Scleroptila elgonensis
A pretty, intricately marked medium-sized francolin with a brown back, rufous underparts, and a white throat bordered with black spots. The wings show large rufous patches in flight. Found at high elevations in alpine grassland and heath, often in small groups. Similar to Shelley’s Francolin, but found in different habitat at higher elevations, and separated by many details, including the more solidly rufous underparts without heavy black barring on the belly. The vocalizations include a series of “squee-chee” notes, and a squealing call often given in flight.
Black-capped Petrel
Pterodroma hasitata
A long-winged, black-and-white bird that is most often found far out at sea, coming to land only to breed on remote cliffs from November into May. Adults visit the nest sites only at night, when it is possible to hear this species vocalizing. The rather similar Bermuda Petrel lacks this species’ white collar and white rump. Black-capped Petrels also have a darker headed or “cowled” appearance than Bermuda Petrels. Calls at nesting areas include a drawn out “awwwww” that often grows louder towards the end and is usually given in series, sometimes with a squeaky hiccuplike terminal note that has an oddly donkey-like quality. Also gives a puppy-like yelp.
