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.

Pale Spiderhunter
Arachnothera dilutior
A medium-sized bird of lowland and foothill forest and edge with a very long curved bill. Has a preference for banana plants. Grayish on the head and back with olive-green wings, a pale gray throat and chest, and a pale yellow belly. Note the yellow eye-ring and white tips to the undertail. Somewhat similar to Naked-faced Spiderhunter, but smaller and paler. Also similar to females of several sunbird species, but larger and longer-billed. Voice includes a sharp, nasal “rek!”
Golden Palm Weaver
Ploceus bojeri
Breeding male is bright yellow with a mostly orange head. The female is duller, though still very yellow. Both sexes show a dark eye in all plumages. Found in coastal savanna and scrub, often in areas with abundant palms, and inland along rivers through dry country. Similar to African Golden-Weaver, and ranges overlap, but separated by the blackish rather than red eyes. Vocalizations are typical of weavers: “chet” notes and a sizzling “radio static” song.
Puerto Rican Amazon
Amazona vittata
A chunky green resident of moist upland forests. No other native parrots occur within its range, but the Red-crowned Parrot, native to Mexico, is often kept in captivity and looks very similar. Compared to the Puerto Rican Parrot, the Red-crowned has more extensive red on the forehead, has a small red patch on its wings, and has gray, not pinkish-colored, legs and feet. Calls include a loud harsh “wee-uh.”
