Greater Flameback
Chrysocolaptes guttacristatus
A large, crested woodpecker with a golden back found in wet tropical and subtropical forests across South and Southeast Asia. Separated from Common Flameback and other “small-billed” flamebacks by a much larger bill, a mottled black-and-white nape instead of a black nape, and a divided black horizontal stripe below the cheek. Separated from the similarly large-billed White-naped Woodpecker by a red rump, the lack of a clean white nape, and a preference for wetter habitat. Greater Flameback is a loose participant in mixed-species foraging flocks, often detected by its loud, high-pitched trill similar to that of Common Flameback.
识别特征
The greater flameback is a large woodpecker, at 33 cm in length. It is of typical woodpecker shape, and has an erect crest and a long neck. Coloration is highly variable between subspecies; it always has unmarked golden-yellow to dark brown back and wings. The rump is red and the tail is black. The underparts are white with dark markings (chevrons, stripes, or bands), or light brown. The head is whitish with a black pattern, or it is yellow, brown, or red. The straight-pointed bill is longer than the head, and the legs have four-toed zygodactyl feet (two toes pointing forward, two backward) and are lead-grey in color. The eyes' irises are whitish to yellow.<p>The adult male greater flameback always has a red crown. Females have a crown color varying between subspecies, such as black spotted with white, yellow, or brown with lighter dots. Young birds are like the females, but duller, with brown irises.<p>White-and-black-headed greater flameback subspecies resemble some of the three-toed Dinopium flamebacks, but are not particularly closely related. Unlike the black-rumped flameback (D. benghalense) and the common flameback (D. javanense), the greater flameback's dark moustache stripes are divided by white (making them inconspicuous at a distance); except in C. stricklandi, their hindneck is white (not black), and even in the Sri Lankan birds, the dark colour does not extend to between the shoulders as it does in Dinopium; consequently, when seen from behind, the black-and-white-headed greater flamebacks outside Sri Lanka show a white neck bordered with black on the sides, while the Dinopium species have a black neck and upper back, with thin, white borders to the neck. Those flamebacks are also smaller (though this is only reliable in direct comparison), have a bill that is shorter than the head, and dark irises.

Common Ostrich
Struthio camelus
Massive, conspicuous, flightless bird with long neck and robust legs. Mature males have black-and-white plumage, with pinkish skin, flushed in breeding plumage. Females and immatures are duller gray-brown. Small groups roam open and lightly-wooded country; can walk up to several kilometers a day. The stubby wings are used for spectacular breeding displays and dust-bathing. Deep booming calls can be heard from long distances. Similar Somali Ostrich (no range overlap) has slaty-colored skin and pale eyes, unlike the pink-skinned Common Ostrich.
Louisiade Flowerpecker
Dicaeum nitidum
A tiny bird of forest canopy on the southeast islands of New Guinea. Medium gray above and pale gray below with whitish throat and yellowish belly. Large, bright red rump and small red crown patch. Male has glossy green wing and red chest patch. The female’s whitish throat extends to the chest. The only flowerpecker in range. Smaller and shorter-billed than a female Purple Sunbird. Song, a short, up-and-down, high-pitch melody.
Jerdon's Nightjar
Caprimulgus atripennis
Large-headed nightjar with a bright white throat. Male shows bright white patches near the wingtips and on the edges of the tail that are buffy-brown in females. Large-tailed Nightjar is very similar; in Jerdon’s, look for less-streaked crown and smaller wing patches. Indian Nightjar is smaller and much more intricately patterned, lacking the white throat. Song is a strange bubbling “bwr-wr-wr,” usually heard at dusk or dawn in wooded areas.
