Purple-winged Roller

Coracias temminckii

A distinctive big-billed bird that is entirely deep purple in color except for a conspicuous sky-blue cap and rump. Juvenile has a duller cap and browner underparts. Sits upright. Prefers open country near wooded and forested areas, where it is most often seen perched high on prominent dead branches, usually singly or in pairs. Occurs in both lowlands and foothills. Gives a harsh, dry grating call, “ka-ka-ka-ka…”, and sometimes also a single “chowwEER.”

识别特征

The purple-winged roller is 30–34 cm (12–13 in) in length, similar in size to the Eurasian jay. The cap and upper-tail coverts are bright azure blue, the back is dark-olive, with the rest of the plumage mainly dark blue. The large bill is black. The sexes are alike. Juveniles are similar to the adults but with duller plumage.

分类信息

The purple-winged roller was formally described in 1819 by the French ornithologist Louis Pierre Vieillot under the binomial name Garrulus temminckii. The specific epithet was chosen to honour the Dutch ornithologist Coenraad Jacob Temminck. The type locality is the island of Sulawesi. The purple-winged roller is now one of nine species placed in the genus Coracias that was introduced by Carl Linnaeus in 1758. A molecular phylogenetic study published in 2018 found that the purple-winged roller was most closely related to the Indochinese roller (Coracias affinis).<p>The phylogenetic relationships among the Coracias species are shown below, from the molecular study by Johansson et al. (2018)<p>Alternate names for the purple-winged roller include the Celebes roller, Sulawesi roller, and Temminck's roller.

Gray-crowned Crocias

Gray-crowned Crocias

Laniellus langbianis

Resembles a three-way cross of a shrike, a sibia, and a laughingthrush. Black robber’s-mask, warm orange-brown back, streaked white underparts, and long gray tail with white tips below. Often seen in pairs of small flocks, sometimes mixed in with other species. Forages in the canopy, clambering around in search of prey. Inhabits mid-elevation forest, often in wetter areas. Song is a series of rapid-fire high-pitched chitters.

Helmeted Hornbill

Helmeted Hornbill

Rhinoplax vigil

Bizarre-looking bird, now very rare due to poaching for the ivory-like material of its bill. When perched, its most recognizable feature is the naked throat pouch which resembles an undercooked steak, chalky white in the female and dull scarlet in the male. When in flight, its long trailing central tail feathers easily distinguish it from any other hornbill. Scarce and difficult to see; listen for its far-carrying maniacal laugh in mature lowland and foothill forests.

Black-crowned Sparrow-Lark

Black-crowned Sparrow-Lark

Eremopterix nigriceps

Small, finchlike lark of arid zones with strong sexual dimorphism. Male is striking with black underparts, whitish cheeks, and black crown. Female is overall gray-brown overall and lightly-streaked; best identified by short, heavy bill. In flight shows dark underwing coverts and black tail (from above black tail sides). Breeds on desert plains with scattered bushes. Song is a repetitive short phrase of clear, high-pitched whistles. Call is a short, buzzing "Zzz" or "Zik, zik…"
