Red-cowled Widowbird
Euplectes laticauda
A small widowbird. The breeding male is jet black, with a crimson collar and crown, and a 20-centimeter floppy graduated tail. The female and non-breeding male have dark streaked upperparts, pale unstreaked or faintly streaked underparts, with a buffy band across the breast, and a yellowish eyebrow and face, and lack the long tail. Pairs breed at middle and high elevations, in open grassland, savanna, scrub, and cultivated areas. The species may flock, often with other seedeaters, and move locally when breeding is over. Breeding males are distinctive, but non-breeding males and females can be confused with many other species. Can be tentatively identified by the lack of red or yellow in the wing, along with a buffy breast that is unstreaked or only lightly streaked.

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.
Henderson Petrel
Pterodroma atrata
A typical uniformly grayish-brown petrel with pale mottling at the base of the bill that gives it a somewhat “frosted” facial appearance. Pale bar along the leading edge of the underwing between the body and elbow is evident in flight. Highly pelagic, visiting land only to nest. Similar to Kermadec Petrel, but lacks the white primary shafts in the upperwing of that species and is overall more uniformly colored. Providence Petrel is similar but appears much heavier-chested and paler-faced, with more extensively mottled gray-brown tones across the body. Herald Petrel is very similar, but has much more contrasting dark-and-light underwing pattern. Henderson Petrel is silent at sea.
Millerbird
Acrocephalus familiaris
A small old-world warbler that occurs only on Nihoa and Laysan in the Northwestern Hawaiian Islands. Unlikely to be confused with any other species; the only other passerines on those islands are finches. Does not occur on the main Hawaiian Islands. Prefers dense, low vegetation. Usually secretive and hard to see well, but males sometimes sing from an exposed perch. Song and calls are harsh chirps and churring.
