Brown-backed Flowerpecker

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 medium-sized, ground-dwelling bird of mossy montane forest. Brown streaked back, gray and buff wing bars, and gray face, extending down the sides of the chest. Male has a white throat and chest whereas in the female it is orange, both edged with a black line. Very skulking and hard to see. Forages by scratching the leaf-litter. Not really similar to any other ground-dwelling birds in the mountains. More often heard than see. Song is a very distinctive, descending series of clear, penetrating, whistled notes which sound slightly out of tune.

Small gracile bulbul with brown upperparts, dirty-yellow underparts, and surprised-looking large dark eye accentuated by yellow eyering. Somewhat like a babbler in proportions and behavior; forages, often with mixed flocks, at lower and middle strata of forests. Inhabits mature and advanced secondary forests from lowlands up to around 1,000 meters. Scolds “chee-chuu” repetitively and gives soft ascending whistles.
