White-bearded Greenbul
Criniger ndussumensis
A medium-sized greenbul often found in flocks in forest and forest edge with other bearded-greenbuls. Like all bearded-greenbuls, will sometimes puff out throat feathers. Often forages actively along trunks and large branches. Shows a grayish head, a bright white throat, yellow-green underparts, and olive-green upperparts with a reddish tail. Nearly identical to Red-tailed Greenbul, and can occur with it in the same mixed-species flocks in Central Africa. Not all individuals can be safely identified. Listen for White-bearded Greenbul’s distinctive calls as it forages on large branches and trunks, and look for its duller red tail and, at close range, its thinner, smaller bill and more slender build. A vocal species, frequently giving “hut-TYER-CHUR!” or similar short, gruff calls.
Taxonomy
The white-bearded greenbul was originally described as a subspecies of the red-tailed greenbul and alternatively has been considered as conspecific with the yellow-bearded greenbul. Alternate names for the white-bearded greenbul include the slender-billed bearded bulbul, Uganda red-tailed bulbul and white-bearded bulbul.

Streak-throated Swallow
Petrochelidon fluvicola
A small brown-black swallow with a short tail and comparatively weak flight. The forehead, crown, and back of the neck are dull chestnut with faint dark streaks. The back is glossy deep blue with a few narrow whitish streaks; the rump is pale brown and is more prominent in flight. The wings and tail are blackish-brown, and the tail almost square-ended. Underparts are buffy white with blackish-brown streaks, especially the chin, throat, and upper breast. Juvenile is duller and browner than adult, with buff feather edges and faint streaks on underparts. Found mostly as individuals in mixed swallow flocks; different, weaker flight action is characteristic.
White-browed Bulbul
Pycnonotus luteolus
A plain brownish bulbul that is endemic to the bottom half of peninsular India and Sri Lanka. Ubiquitous inhabitant of scrubby habitat across its range and sometimes overlaps with Yellow-throated Bulbul in rocky scrub. Although both species have a yellow vent and can sound similar, White-browed can be distinguished by its brown face and white eyebrow. Usually occurs in pairs and tends to skulk in undergrowth. Rather noisy but uncommonly seen, listen for regular, short bursts of distinctive raucous babbling.
Christmas Shearwater
Puffinus nativitatis
A medium-sized shearwater with uniformly dark brown plumage and no contrasting markings. Flies more steadily than most shearwaters and usually flies low over the water. Large numbers nest on most of the Northwestern Hawaiian Islands. A few pairs nest on Moku Manu Islet off the eastern coast of Oahu. Often seen from boats in the Northwestern Hawaiian Islands, but rarely on the main islands and rarely from shore. The voice, usually heard only at breeding colonies, is a low moan.
