Timor Heleia

A brilliant and brash resident of thornscrub, cactus forests and other arid landscapes. Rather large-headed, often sporting a short shaggy crest, with a blue teardrop of bare skin around each eye, thus differing from most other orioles. Also note the long white slash on each wing. The Baltimore Oriole is passingly similar, but it is smaller, less bulky, and has less black on the chest than Venezuelan Troupial. Vocalizations are mostly loud and flutelike. They include an upward inflected “chu-wee,” a down slurred “shee-oo,” a quick series “thank-you, thank-you, thank-you, chu-eee, che-ee, chu-ee,” and “Chu-oo-eee-o.”

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.

A large seedeater with a very thick pinkish bill. Brownish-olive above and yellow below with streaking along the sides. Males are slightly brighter and have thicker streaking below. Both sexes have a yellow rump that is conspicuous in flight. Found in dry thorn savanna and thorn scrub, usually in pairs or small groups. Similar to Brimstone Canary, but distinguished by the notably larger bill, streaked underparts, and yellow rump. The song is twittering, high-pitched, and variable, and can include imitations of other species. The most common call is a sliding “sreeyu.”
