Hispaniolan Trogon
Priotelus roseigaster
This strikingly colored denizen of montane woodlands (and less often, mangrove swamps) is rather sedate. It is often found sitting upright and rather motionless, typically in pairs. One's first impression is often of a rather long and largish bird with a brilliant red belly, emerald back, and blackish head. No similar species occur within its range. Song is a tremulous “whut-will,” with second note longer and trailing off at end. The first note is sometimes omitted and second note is sometimes given as doublet or triplet. Calls include a shrill “whee” and soft coos. Though rather vocal, calling birds are difficult to locate due ventriloquial quality of their vocalizations.

分布与栖息地
Its natural habitats are subtropical or tropical moist montane forests, and heavily degraded forest. It is threatened by habitat loss. It is mostly confined to a few remaining protected areas. It inhabits rain, dry, pine and broadleaved deciduous forests. Several early records included mangrove swamps west of Miragoane but whether these were visitors or a resident population is unknown.It requires large, old decayed trees with holes for nesting. It primarily occurs at 500–3,000 m, but there appears to be some altitudinal migration with birds observed at lower elevations in winter. In Haiti, it is restricted to the Massif de la Hotte and Chaîne de la Selle, due to extensive habitat loss. It is still quite common in the Dominican Republic, especially in the relatively undisturbed Sierra de Baoruco, although there has been a moderately rapid population reduction, owing to deforestation.

行为
Its foraging behaviour is presumed to be similar to that of other species of trogon: most food is taken in aerial sallies to fruit or to surrounding vegetation. The species primarily forages in the midstory of humid deciduous and pine forests. A study of mixed-species flocks on Hispaniola recorded two encounters with the Hispaniolan trogon, both of which were associated with mixed flocks.

Chubb's Cisticola
Cisticola chubbi
Large, plain montane cisticola. The most outstanding aspects of the plumage are a reddish cap and two bands across the tip of the tail, one pale and one black. Found in open montane habitats with thick herbaceous undergrowth, including forest edge, grassland, and heath. Almost always in pairs or small groups. The distinctive song is given in chorus: a frantic up-and-down series of scratchy notes. As with other cisticolas, habitat and vocalizations are important to identification. Fairly similar to Singing Cisticola, but lacks a rufous panel in the wings.
Brown-winged Parrotbill
Suthora brunnea
Gregarious long-tailed inhabitant of grassy and scrubby areas, as well as bamboo stands and secondary growth, in mountains and foothills. Very similar in appearance to Vinous-throated Parrotbill (range overlap minimal) but with a brighter orange head, stronger and more noticeable throat streaking, and no warm orange or reddish tones in the wings. Moves about noisily through dense vegetation, twittering and chattering constantly.
Ashy Woodswallow
Artamus fuscus
A chunky, large-headed bird of open areas, usually found perched on wires or flying around in search of insects. Soft gunmetal gray with white underparts. Often found pressed together in pairs or tight groups when at rest. Sometimes flies in the same areas as swallows and swifts, but has a much thicker build, with triangular, somewhat starling-like wings. The only woodswallow throughout most of its range. Song is a somewhat myna-like series of sweet warbling and harsh chattering. Also gives nasal scolding “nyeh”, comparable to a jay or treepie.
