Swallow Tanager
Tersina viridis
Unique small tanager, widespread in lowlands and foothills up to 1,800 m. Male is bright cerulean with a black mask, white lower belly, and some black bars on the sides. Female is mossy green with paler yellow belly and scalloped barring on the sides. Behavior much different from other tanagers: perches upright, often on exposed branches or treetops, and sallies out for insects like a flycatcher. Usually seen in pairs or small loose groups. Found at forest edges, clearings, or gardens.
识别特征
The swallow tanager is 14.5–15 cm (5.7–5.9 in) in length with a broad flat bill. This bird is strongly sexually dimorphic. The male is bright turquoise blue with a black face and throat. The turquoise flanks have black barring and the lower belly is white. The female is bright green with dusky-olive barring on the flanks. She lacks the black face mask. They are gregarious but do not associate with other species. They mainly eat fruit but they will also sally after insects from an exposed perch. The swallow tanagers are unique among tanagers in that they will sometimes dig a hole in a bank for a nest.
分类信息
The swallow tanager was formally described in 1811 by the German zoologist Johann Karl Wilhelm Illiger under the binomial name Hirundo viridis. The type locality is eastern Brazil. The species is now the only member of the genus Tersina that was introduced in 1819 by the French ornithologist Louis Pierre Vieillot. The genus name is from the French Tersine, an unidentified bird described by Georges-Louis Leclerc, Comte de Buffon. The specific epithet viridis is the Latin for "green". A molecular phylogenetic study of the tanager family published in 2014 found that the swallow tanager is sister to the honeycreepers in the genus Cyanerpes.<p>Three subspecies are recognised:

White-billed Buffalo-Weaver
Bubalornis albirostris
A big, bulky, long-tailed black weaver. The bill is white in males and black in females. There is a white patch on the front edge of the shoulder, and also a pale patch in the wing that can be conspicuous in flight. Immatures are dark brown with heavy streaking below. Found in dry savanna and woodland, often in flocks. Builds huge communal stick nests. Similar to Red-billed Buffalo-Weaver, but never shows a red bill. The common call is a harsh “sjet” that is often given repeatedly by a whole group in chorus.
Pale-footed Swallow
Orochelidon flavipes
Uncommon swallow in montane forest in the Andes from Venezuela to Bolivia. Similar to the more common Blue-and-white Swallow, but look for the buffy throat and browner flanks on Pale-footed Swallow. Found in flocks, usually not far from forest. Not frequently found around human settlements unlike Blue-and-white Swallow. Occurs from around 2,400–3,200 m.
Crimson Shining-Parrot
Prosopeia splendens
A large, brightly colored parrot with a red head and underside and a bright green upperside with a blue hind neck and tail. Occurs in a variety of habitats. Similar to Red Shining-Parrot, but has brighter red underparts and head with duller brownish orange eye; the two occur on nearby islands but do not overlap. Voice is typical of parrots, including a variety of nasal “erh” and “grrraah” calls.
