Pale-billed Flowerpecker
Dicaeum erythrorhynchos
A tiny nondescript bird with a pale and bulky curved bill. Endemic to the Indian subcontinent where it can occur in any habitat that is not too dry, too wet, or too high. Shows a particular fondness for Singapore Cherry berries. Often only seen in flight making a fast “thik-thik” call that recalls Nilgiri or Plain Flowerpecker. Songs include a unique high-pitched trill. When not singing, a view of the bill is essential to identify the species in any region where either of Nilgiri or Plain flowerpecker is also present.
识别特征
This is a tiny bird, 8 cm long, and is one of the smallest birds occurring in most parts of southern India and Sri Lanka. The bird is plain brownish to olive green. The underside is buff olive and does not contrast greatly with the upperparts and not whitish as in the Nilgiri flowerpecker of the Western Ghats and Nilgiri hills nor is it streaked as in the thick-billed flowerpecker. The Nilgiri flowerpecker has a pale supercilium unlike this species which has no marking on the head. The Sri Lankan race ceylonense Babault, 1920 - is greyer and smaller than the nominate race of peninsular India. It has been considered one of the early flowerpeckers, originating in the Malay Peninsula, to colonize the Indian Subcontinent.

行为
In forested areas, they often visit the flowers of Loranthus (=Dendrophthoe) and Viscum species, the seeds of which are dispersed mainly by this and other flowerpecker species. The berries of these epiphytic parasites are usually swallowed whole (they sometimes pinch fruits and discard the seeds while feeding on the pulp but this technique is more often used by the syntopic thick-billed flowerpecker) and the seeds are voided after a rapid passage through their gut in about three to four minutes. The voided seed has a sticky coating and the bird applies its vent to the surface of a suitable perch and may turn around so as to get rid of the seed, which then sticks onto the branch where it may subsequently germinate. The flowers of Dendrophthoe falcata are pollinated by this species. The flower bud has a mechanism that causes pollen to explosively spray on the plumage of the visiting bird which nips the tips.<p>In urban areas, they are particularly attracted to introduced fruit trees such as Muntingia calabura, the fruits of which may be swallowed whole or, in the case of ripe berries, crushed and the pulp accessed using their tongue. They also sip nectar from flowers such as those of Sterculia colorata and Woodfordia floribunda, pollinating them in the process.<p>Tickell's flowerpeckers breed from February to June. A second brood may be raised in September. The nest is a small pendant purse-like structure made of cobwebs, fibre, moss and down suspended from the tip of a twig high up in a tree. The opening is a slit and a clutch of two or three eggs is laid.

Jambu Fruit-Dove
Ptilinopus jambu
The plum-red face and pink “blush” on the white chest of the cartoonish-looking male are unique. Plainer female and juvenile can be difficult to separate from female Black-naped Fruit Dove; look out for Jambu’s bright white eye-ring and orange bill. Generally uncommon and nomadic; roams widely across lowland and foothill forests, where it seeks out fruiting trees. Forages quietly in the canopy, typically singly or in pairs.
Black-faced Grassquit
Melanospiza bicolor
Small sparrowlike bird found in the Caribbean and northern South America. Males are dull olive above with a variable amount of black on the face and breast. Females are plain grayish-olive overall; note the small size, short tail, and pinkish bill and legs. Very similar to female Sooty Grassquit. Found in pairs or small groups in shrubby or grassy areas and forest edge, typically on or near the ground.
Rüppell's Griffon
Gyps rueppelli
Huge vulture, slightly smaller than Eurasian Griffon. Adults have dark-bodied with pale feather tips on body and shoulders, giving them a scaled appearance; also note pale bill and eye. Juveniles are dark with a characteristic pale bar on the leading edge of the underwings and have a black bill and dark eyes. Nests on cliffs and is generally silent except when squabbling at carcasses. Often encountered foraging over grasslands and soaring along cliffs and ridgelines.
