Madagascar Martin
Riparia cowani
Small, very plain brown swallow with a white belly. Found in a variety of open habitats, including marshes, rice paddies, other agricultural fields, secondary forest, and montane heathland. Found at middle and high elevations, and absent from the lowlands. Most often seen on the wing, sometimes in flocks, which can also contain other species of swallow or swift. Weak, fluttering flight. The common vocalization, usually given in flight, is a short, slightly descending rattling trill. Somewhat similar to Mascarene Martin, but much smaller and plainer, lacking streaking on the underparts.
分类信息
The Madagascar martin was formally described in 1882 by the English ornithologist Richard Bowdler Sharpe based on specimens collected by the Scottish naturalist William Deans Cowan in montane southeast Madagascar. Sharpe coined the binomial name Cotile cowani, choosing the specific epithet to honour the collector. It is now one of six martins placed in the genus Riparia that was introduced in 1817 by the German naturalist Johann Reinhold Forster. The Madagascar martin was formerly considered to be conspecific with the brown-throated martin (Riparia paludicola) but was split based on the different morphology and vocalization. The species is monotypic: no subspecies are recognised.

Palau Fantail
Rhipidura lepida
Small, with a long, often fanned tail. Mostly pale orange-red with a gleaming white throat and a black chest with gray sides. Note the small black eye mask. Mostly resident in forest, but sometimes forages in open scrub. Common vocalization is a soft whistle or raspy “me-EE-ow.”
Baird's Flycatcher
Myiodynastes bairdii
Large, stout-billed flycatcher restricted to arid areas and oases of northwestern Peru and western Ecuador. Distinctive in range, with yellow belly, chestnut wings and tail, and black mask. It does not occur together with the similar Golden-crowned Flycatcher, which is a cloud forest species. Typically sits high up on a tree, pole, wire, or other elevated perch. Sallies out to catch insects, and also regularly eats fruit.
Gray-streaked Flycatcher
Muscicapa griseisticta
Small and streaky flycatcher, with longer-winged appearance than Asian Brown and Dark-sided Flycatchers. Breeds in mixed and deciduous forest in lowlands and hilly regions. Dark brown above, white below, with distinct pale eyering and long, dark streaks below. Streaking can resemble the patterning of some Dark-sided Flycatchers but is more distinct, less smudgy-looking. Asian Brown Flycatcher shares the same general color scheme but is paler brown and lacks streaking.
