Brown-backed Needletail
Hirundapus giganteus
A very large swift with broad wings pinched at the base, a protruding front, and a bulky rear. Short tail has well-defined spines that can be seen even in fast flight. It has blackish-brown upperparts with a pale-brown saddle, often difficult to make out; the underparts from the throat to the lower breast are dark brown, ending in a well-demarcated deep “V” that contrasts strongly with the white belly, vent, and undertail. When seen well, it shows white lores, a feature absent in other large needletails. It has an extremely fast and powerful flight and hence can suddenly appear from nowhere and disappear quickly.

Adelaide's Warbler
Setophaga adelaidae
A small, brightly colored inhabitant of thickets in woodlands and scrub. Feeds actively, snatching insects from leaves and twigs. It is passingly similar to the Northern Parula, but the parula has yellow-green on its back and the yellow below does not extend onto the belly as it does on Adelaide’s. Its song is series of rapidly given sweet notes that accelerate as the song progresses before sometimes slowing again towards the end. Call is a sweet “chick” with a slight squeaky quality.

Timor Green-Pigeon
Treron psittaceus
Fruit-loving, forest-dwelling pigeon with the coloration of a green mango. Gathers in flocks in fruiting trees and races by overhead in fast, direct flight. Note darker-centered feathers under the tail and bright yellowish linings on the wing feathers. Black-and-white outer tail edges are often exposed in flight. The only green-pigeon on Timor; all-green plumage readily separates this species from imperial-pigeons and fruit-doves. Very rare or extirpated in Indonesian West Timor, and declining in East Timor due to hunting and habitat loss. Gives oddly creaky rising coo: “aw-woo-wUUOO.”

Cook's Petrel
Pterodroma cookii
A small, fast-flying petrel with long narrow wings and bright white underparts. Found singly or in loose aggregations, well offshore in warmer Pacific waters, mainly from March to August. Flight varies from low and weaving, into the wind, to high and arcing across the wind. Note gray cap and upperparts with dark M pattern across upperwings and dark tail tip. Underparts are white with very narrow black margins to wings. Many birds off Mexican coast are in wing molt.
