White-rumped Spinetail
Zoonavena sylvatica
A small swift with short square tail (rounded when spread), a relatively large head, black upperparts, and a white rump patch. It has a distinctive wing shape with a hooked outer wing and a bulging mid-wing that is pinched at the base. Underparts grade from a brown-gray throat to a pure white belly without any sharp demarcation. Spines on the tail are minute and hard to discern in the field. Flight action, with rapid wingbeats and short glides, is different from that of Little Swift. Mostly seen in flocks, sticking to woodlands and hills, though it descends to the adjoining plains just after showers.

Other Birds
Lineated Woodpecker
Dryocopus lineatus
Large ‘woody woodpecker’ of tropical forest in lowlands and foothills. Also ranges into semi-open areas with tall trees, mangroves, and other lightly wooded habitats. The tufted red crest and black face distinguish it from adult Pale-billed Woodpecker, which often occurs in the same areas. Also note that the white ‘braces’ on the back of Lineated are widely spaced, unlike Pale-billed. Laughing call suggests a flicker, and very unlike calls of Pale-billed.
Red-collared Lorikeet
Trichoglossus rubritorquis
Large lorikeet. Very colorful, with a bright orange breast and neck, blue/black belly and head, and red bill. Very conspicuous, often observed calling loudly while flying overhead or feeding. Varied Lorikeet is much smaller and shorter-tailed; no range overlap with Rainbow Lorikeet, which has a yellow neck and red breast. Found in a wide range of habitats. In the evening and early morning can be seen roosting in very large, noisy flocks.
Silvery Wood-Pigeon
Columba argentina
Beautiful grayish-white pigeon with black wing- and tail-tips. Rare, little-known, and extremely localized; now found only on islands off western Sumatra (though may occasionally wander onto the main island), where it forages in lowland and hill forest. Vocalizations poorly understood and seldom heard; documented giving deep, sonorous, rising coos.
