Green-tailed Warbler
Microligea palustris
Secretive, found in montane thickets and scrub, typically in or near forests. Usually solitary and rarely found in mixed feeding flocks. Soft gray of body and head contrast sharply with olive-green back and wings. It is similar to White-winged Warbler, but is gray rather than white below, has red eyes, and lacks white on the tail and wings. Song is a series of loud, sharp “tsip” notes. Calls include loud squeaky notes and raspy scolds.
识别特征
The green-tailed warbler is 12 to 14.5 cm (4.7 to 5.7 in) and weighs 9.5 to 15.2 g (0.34 to 0.54 oz). The sexes are not particularly dimorphic. Adults of the nominate subspecies have a gray head and nape, pale to dark gray lores, and white arcs above and below the eye. The eye itself is ruby red. Their upperparts are olive-green, and their underparts pale grayish that is whiter on the belly. The subspecies M. p. vasta is overall paler than the nominate and has more white on the underparts.
分类信息
The green-tailed warbler is the only member of genus Microligea, though the white-winged warbler (Xenoligea montana) was originally also placed there. The two species were originally placed in the New World wood warbler family Parulidae, but taxonomists were unsure if they belonged there. DNA evidence published in the early 2010s showed they were not related to other wood warblers, and in 2017, they were moved to the newly created family Phaenicophilidae. The two species in the genus Phaenicophilus were also moved there from the "true" tanager family Thraupidae.<p>The green-tailed warbler has two subspecies: the nominate M. p. palustris, and M. p. vasta. A poorly-defined population in northwestern Haiti may prove to be a third subspecies.

分布与栖息地
The nominate subspecies of the green-tailed warbler is found in the highlands of central Hispaniola that span the border between Haiti and the Dominican Republic, though it is found almost entirely in the latter country. There it inhabits broadleaf and pine montane forest with a dense understory at elevations up to about 2,900 m (9,500 ft). The subspecies M. p. vasta is a disjunct population found in the southwestern Dominican Republic lowlands and Beata Island. There, it inhabits semi-arid scrublands near sea level. There is some discussion that the mainland population belongs either to the nominate or a third subspecies, and that M. p. vasta is limited to Beata.

行为
The green-tailed warbler is a year-round resident throughout its range.<p>The green-tailed warbler forages in vegetation, usually in the undergrowth and thickets. Its diet is mostly arthropods, especially insects. It forages alone, in pairs, and in mixed-species foraging flocks.<p>The green-tailed warbler's breeding season is mainly from May to June in the highlands and begins a bit earlier in the lowlands, though the species is suspected to breed at any time of year. It makes a cup nest of plant material. In the lowlands it is usually placed 1 to 2 m (3 to 7 ft) above ground, sometimes in cacti, and in the highlands can be placed as high as 10 m (30 ft). The clutch size is two to four eggs. Nothing else is known about the species' breeding biology.<p>The green-tailed warbler makes "[s]hort rasping and squeaking notes" that may accelerate into what is thought to be its song. The song has also been described as "sip sip sip".

Ashy Cisticola
Cisticola cinereolus
A large, long-tailed, streak-backed upland cisticola. Note the lack of rufous or rich brown in the plumage, and also the pale tips to the tail. Found in dry thorn savanna and thornscrub. Similar to other cisticolas, especially Rattling, Tana River, and Boran, but identified by its song and by the absence of rufous or brown on the cap. Often sits on top of bushes and trees to sing. Song is a short musical whistled phrase, usually with a downward pitch trend, but sometimes trending upward. Much more musical than the song of Boran Cisticola, often with more variation in pitch. The calls are high-pitched squeaks.
Rufous-throated Solitaire
Myadestes genibarbis
A medium-sized resident of dense, moist montane forests. Its appearance is unique, with its largely leaden gray plumage contrasting with a brilliant brick-red throat and lower belly (note: on Saint Vincent it is largely black above). Perches motionlessly, except when sallying forth after insects and fruit. Usually first located by its voice. Song is a series of drawn out, uninflected flutelike whistles given at varying pitches; call is similar, but notes are shrill.
Minas Gerais Tyrannulet
Phylloscartes roquettei
Small flycatcher with a long tail. Olive-green above, yellowish below, with two yellow wingbars. Look for the rusty lores, but these may be difficult to see. An inhabitant of dry forests, including gallery forest and tall riverine scrub, where it forages at higher levels and only rarely accompanies mixed-species flocks. The song is a series of low rattling notes.
