Chestnut-headed Bee-eater
Merops leschenaulti
Beautiful, dainty bee-eater with a bright reddish head and yellow throat. Dark “necktie” most noticeable when in flight overhead. Inhabits forest edge, wooded clearings, and open areas with clusters of trees; often uses exposed perches. Some populations undertake regional movements, vacating breeding grounds after the monsoons pass. Often gives bright chirrupy calls.
识别特征
The chestnut-headed bee-eater is 18–20 cm (7.1–7.9 in) in overall length and weighs 26–33 g (0.92–1.16 oz). The sexes are similar in appearance. The forehead, crown, nape, mantle and ear-coverts are bright chestnut. The lores are black, continued as a thin band under the eye and ear-coverts. The wing coverts, lower back and tertials are green, the latter are tipped with bluish. The rump and uppertail coverts are pale shining blue. The primaries and secondaries are green, rufous on the inner webs, and all tipped dusky. The central tail-feathers are bluish on the outer, and green on the inner webs; the others are green, margined on the inner web with brown and all tipped dusky. The sides of the face, chin and throat are yellow; below this a broad band of chestnut extending to the sides of the neck and meeting the chestnut of the upper plumage; below this again is a gorget formed by a short distinct band of black and then an ill-defined band of yellow. The remainder of lower plumage is green tipped with blue, especially on the vent and undertail coverts. The iris is red, the bill is black, the legs are dusky black and the claws dark horn-colour. The juveniles are like the adult but duller. They a green forehead, forecrown and mantle. The lower throat is yellow rather than chestnut and the gorget band is indistinct. The breast and belly are paler and more olive in colour than the adult.<p>The Javan sub-species, M. l. quinticolor, differs in having the space from the bill down to the black pectoral band pure yellow without any chestnut, and in having an entirely blue tail. Race andamanensis found in the Andamans is slightly larger than the Indian race.
分类信息
The chestnut-headed bee-eater was formally described in 1817 by the French ornithologist Louis Pierre Vieillot under the current binomial name Merops leschenaulti. He specified the locality as Java. This was an error as this species does not occur there and the locality has been designated as Sri Lanka. The specific epithet was chosen to honour the French naturalist and collector Jean-Baptiste Leschenault de La Tour who had brought Vieillot's specimen to France.<p>Three subspecies are recognised:

This is a bird which breeds in sub-tropical open woodland, often near water. It is most common in highland areas.

行为
These birds are gregarious and feed and roost communally.<p>Chestnut-headed bee-eaters usually nest in small colonies in sandy banks. They make a relatively long tunnel in which the 5 to 6 spherical white eggs are laid. Both the male and the female take care of the eggs and feed the young.<p>As the name suggests, bee-eaters predominantly eat insects, especially bees, wasps and hornets, which are caught in the air by sorties from an open perch.

Black-crowned Pitta
Erythropitta ussheri
Dazzling pitta of Borneo’s lowland dipterocarp forests. Midnight blue above and blinding scarlet below, with a dark head, bright blue wing coverts, and a glowing silver line trailing backwards behind the eye. Garnet Pitta is very similar but has a bright red crown; ranges barely overlap, if at all. Despite incandescent coloration, can be difficult to see as it forages in dense undergrowth; especially favors well-shaded gullies and gulches. Listen for its song, a pure ascending whistle which ends abruptly.
Crimson Seedcracker
Pyrenestes sanguineus
A chunky-billed brown finch with an electric-red rump, red tail, and red hood that extends from the throat to the nape; the hood of the male is larger than the female’s and extends down the flanks. Juvenile is duller than the adult. A secretive and uncommon resident restricted to Upper Guinea, found in pairs in swamp forest, scrub near creeks, and thickets near water in primary and secondary forest; also sometimes in cultivation. Song is a variable series of buzzes and whistles, and call is a strident “tsut…tsut.” Male Black-bellied Seedcracker differs from Crimson by having a black (not brown) back and belly; females and juveniles are almost identical but only overlap in eastern Ivory Coast.
Hainan Leaf Warbler
Phylloscopus hainanus
Beautifully luminous small leaf warbler restricted to the forests of China’s Hainan Island. Bright yellow all over, though darker wings and crown make paler wingbars and eyebrow visible nonetheless. Fairly distinctive in its limited range; Hartert’s Leaf Warbler also has a yellow cast but is duller overall and much larger, with a much more elongated appearance. Song is a short jumble of squeaky high-pitched notes akin to a machine that needs oiling.
