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.
识别特征
The Madagascar martin (Riparia cowani) is a small passerine bird in the swallow family Hirundinidae that is found in montane Madagascar. It was formerly considered to be a subspecies of the brown-throated martin (Riparia paludicola).
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.

Guadeloupe Woodpecker
Melanerpes herminieri
A medium-sized, shy woodpecker that occupies most wooded habitats including mangrove swamps. This is a striking species, clothed nearly entirely in glossy black, save for the deep crimson belly and chest on many individuals. No similar species within range. Calls include harsh, scratchy “rarrrrr” and rapid “cht, cht, cht, cht…”
Slaty Becard
Pachyramphus spodiurus
This flycatcher-like bird of western Ecuador and northwestern Peru can be tough to identify with certainty due to its similarity with the slightly larger One-colored Becard. On male, look for white fringes to some of the wing feathers and a faint, pale spot between the eye and bill. On female, this pale spot is harder to see, but she tends to have a warmer, more tawny-colored breast. Voice is also a good clue: Slaty Becard often gives a ringing, raspy trill. Most common in dry and semi-humid forest but also locally found in humid forest.
Yellow-shouldered Amazon
Amazona barbadensis
Large green parrot of desert Caribbean areas, including mainland. All green with yellow face, yellow shoulder patch, and orange wing patch. Sexes similar. A threatened species, uncommon in areas where it’s trapped for the pet trade but locally common in safer areas. Usually in pairs or groups, often large flocks at roosts. Always in desert scrub areas searching for cactus and other fruits, seeds, and nectar-rich flowers. Voice a harsh scream similar to other Amazona parrots but somewhat higher pitched. Similar to Orange-winged Parrot, which lacks yellow shoulders and has a blue area above eyes.
