Marquesan Swiftlet
Aerodramus ocistus
A medium-sized swiftlet with a relatively long forked tail. Mostly brown with very slightly paler brown underparts and a more golden-brown rump and collar. Most common over rocky riverine valleys and humid forests. Similar to Atiu Swiftlet but is less contrastingly patterned, overall more uniformly brown, with a paler rump and a proportionally longer tail. Also extremely similar to Polynesian Swiftlet, but appears darker-faced and more obviously golden-collared. Vocally similar to Polynesian Swiftlet, with a voice consisting of insect-like buzzing and trilling.

Golden-backed Weaver
Ploceus jacksoni
Adult male is bright yellow with a glossy black head and rusty-orange underparts. Female is dullish yellow overall and can be difficult to distinguish from other female weavers. Look out for Weyns’s Weaver, which has a similar color pattern, but a black back in the male and pale eyes in both sexes. Inhabits wetland areas and builds an oval nest. Native to eastern Africa; established species in Singapore and the United Arab Emirates.

Bar-tailed Godwit
Limosa lapponica
Gangly wader with a long bicolored bill. Breeding plumage is dark brick-red below (male) or pale orangey (female); nonbreeding plumage is overall gray-brown with white belly; compare to Black-tailed Godwit. In flight shows rather plain upperwings with only a faint whitish wing stripe; white rump and finely barred tail. Mainly coastal away from tundra breeding grounds. Often in flocks feeding on mudflats and in brackish coastal lagoons, roosting in adjacent freshwater habitats. Feeds by probing its long bill into the mud.

Invisible Rail
Gallirallus wallacii
A huge, distinctive all-dark flightless forest rail with a powerful red bill and red legs. Restricted to the island of Halmahera in the North Moluccas, where it occurs in swampy areas within forest, especially sago swamps. Very shy, roaming the forest floor singly or in pairs. Calls include deep drumming noises, and a racket of loud “WAK-WAK-WAK” notes repeated in an agitated-sounding series. Also gives quieter clucking notes.
