Collared Falconet
Microhierax caerulescens
This tiny falcon is usually seen perched high up on an exposed snag towering above open forests. Generally uncommon and sparsely distributed throughout its range. Black above and pale below with rusty red throat and vent. Long dark stripe trailing behind the eye gives the bird a rather comical, panda-like appearance. Social; lives in family groups that are often seen grooming one another.
识别特征
The collared falconet is a very small falcon, shrike-like in shape, mainly pied and having bold white supercilia and collar, with relatively heavy double-toothed bill. It has shortish wings, a medium-length tail, strong half-feathered legs, and powerful feet. It perches conspicuously on top or edge of tree or bush, often on dead twig, frequently bobbing head and slowly moving tail up and down; wing-tips less than half down tail. Sexes are similar.
分类信息
The first description by a European ornithologist was published by George Edwards in 1750, as "the little black and orange colour'd Indian hawk". It was from a specimen that had been collected in Bengal and sent to the king's physician, Richard Mead. In 1758 the Swedish naturalist Carl Linnaeus used the illustration and description by Edwards to formally describe the species under the binomial name Falco cærulescens In 1760 the French naturalist Mathurin Jacques Brisson also used Edwards' publication to describe le Faucon de Bengale. Although the white collar was not mentioned, the English ornithologist Richard Bowdler Sharpe believed that this was the collared falconet. Richard Bowdler Sharpe introduced the genus Microhierax in 1874, from the Greek μικρόσ ἱεραξ meaning "tiny hawk".

Emerald Tanager
Tangara florida
Well-named tanager, mostly emerald-green with trapezoidal black cheek patch, back streaking and wing markings. Small and active, usually found in pairs following mixed feeding flocks in foothill forests and edges. Feeds on fruit. Sexes alike.
Violet Crow
Corvus violaceus
An entirely blackish short-tailed crow. Has a subtle purplish sheen that is visible in only certain lighting conditions. Juveniles lack purple gloss. Inhabits forest, edge, and plantations in the lowlands and foothills. Singles, pairs, or small groups can be found in the canopy. Recently described from Seram, and perhaps also occurs on Ambon and Buru. Unmistakable, being the only crow on these islands. Gives an odd call for a crow: a nasal, trumpeting “errr.” Gives more crow-like sounds too, but higher-pitched than many sounds of the family, including a high-pitched, guttural “kreh-kreh…”.
Blue-winged Laughingthrush
Trochalopteron squamatum
Brown laughingthrush with a black brow and a bright silvery-azure panel on the wing. Wings, belly, and rump are more rufous-tinged than the rest of the body. Not as social as many other laughingthrushes; never found in large flocks, but rather in small groups, pairs, and even occasionally singly. Forages in tangled undergrowth and can be difficult to see; its high-pitched whistles occasionally give it away, but it can be rather quiet.
