Pale-capped Pigeon
Columba punicea
Rare and beautiful pigeon of wooded areas. Predominantly a rich maroon color with a paler breast and gray wingtips. The silver cap is usually hard to see as the bird hurtles by overhead, but is strikingly obvious when perched. Usually forages quietly in the crowns of fruiting trees either singly or in pairs, but will congregate in small flocks at roosts and watering holes.
识别特征
This large 36–40.5 cm-long pigeon is all-dark chestnut brown with a contrasting pale crown. The male has whitish-grey crown, purplish-maroon upperparts with faint green gloss on the neck; more strongly iridescent mantle and back; dark slate-coloured rump and uppertail-coverts; vinous-brown ear-coverts, throat and underparts[ slaty-grey undertail-coverts; and blackish tail and flight feathers. Females have a more brownish-grey crown. Juveniles initially have the crown colour matching the mantle, duller wing-coverts and scapulars with rufous fringes, a much reduced gloss on the upperparts and greyer underparts. The legs are crimson and iris is creamy-yellow in adults. The skin around the eyes and the ceres are magenta.<p>Some taxonomists have grouped it along with Columba argentina which are both Old World pigeons that lack patterns on the back of the neck.

分布与栖息地
The pale-capped pigeon is very locally distributed across its broad range, which encompasses parts of northern and northeastern India, Bangladesh, Myanmar, Thailand, Laos, Cambodia and Vietnam. The type specimen was collected in Chaibasa, Singhbhum, India but relatively few records exist from Peninsular India. Records of the species exist from Maharashtra, Orissa, Bihar and Andhra Pradesh (Araku valley). Observers considered it a seasonal visitor in Sri Lanka. In some parts of Thailand, they are winter visitors and birds have been seen roosting in mangroves far from the mainland.<p>They are found mainly on the forests of the plains. It frequents a wide variety of habitats from the lowlands up to 1,600 m, chiefly primary or secondary evergreen forest, but also open, deciduous dipterocarp forest, bamboo, and agricultural fields, particularly in close proximity to forest. Mangroves, small forested islands and other coastal habitats are probably only frequented in the non-breeding season. It is mainly frugivorous, although seeds and grain form important dietary components in some areas. Tickell noted that the birds were found in groups of 4 to 5, mainly on Eugenia trees near rivers. They ate the berries of these trees, foraging in the morning and evenings and resting during the heat of the day. Layard noted that they favoured Cinnamon trees. It does not appear to have been common in most of its range. It was said to be common on the island of Koh Mur or Pulau Muntia in western Thailand. Recent records indicate that it now only occurs rarely and erratically within its range.

行为
These pigeons fly about in small groups, foraging mainly in the morning and evening. They are said to have a low call similar to that of Ducula aenea but shorter and less prolonged. The breeding season is May to August and the flimsy platform nest is placed low down in a tree and one or rarely two eggs are laid.<p>A species of helminth parasite, Cotugnia joyeuxi Baer, was first collected from this species from a Burmese specimen.

Himalayan Rubythroat
Calliope pectoralis
Shy inhabitant of thickets and dense grassy areas from subalpine scrub to above treeline. Male is gunmetal gray with a white brow, bright orange throat, and a black patch extending from the face down to the breast. Very similar to the closely related Chinese Rubythroat, which has a white moustachial stripe. Chinese Rubythroat female averages browner than female Himalayan, but is best identified by range; Chinese breeds in central and south-central China, while Himalayan breeds along the Himalayas, in Xinjiang, and in Central Asia. Female Himalayan has a weaker eyebrow than female Siberian Rubythroat, and is darker overall.
Sanford's White-eye
Zosterops lacertosus
A distinctive white-eye, mostly dark brown above and buff below. Note the large black beady eye with a broad pale eye-ring, the long yellow bill, and the yellow legs. Most common in primary forest, less common in secondary growth. Common call is a “chip” note. Seldom heard singing.
Dusky Babbler
Turdoides tenebrosa
A very dark babbler with a pale eye. Found very locally in areas of moist woodland with thick undergrowth, almost always in small groups that feed by hopping across the ground. Much more elusive and skulking than most babblers. Similar to Black-lored Babbler, but Dusky Babbler is much darker, and there is virtually no overlap in range. Usually located by the raspy babbling call, typically given by a whole group in chorus.
