Northern Yellow White-eye
Zosterops senegalensis
A small, sharp-billed warbler-like bird that is saturated with yellow. Note the yellow underparts, olive-yellow back, and bold white spectacles around the eyes. There is some geographical variation in the overall coloration, darkness of the back, and extent of yellow above the bill. Found in forest, savanna, scrub, gardens, moist woodland, and plantations, usually in hyperactive flocks that can contain many individuals. Often joins mixed flocks with other small birds. Most common call is a high-pitched rising rattle. Song is a quiet, chatty sequence of “chew” notes. Similar to Pale White-eye, but usually separated by range; shows more yellow above the bill, is more richly-colored overall, and prefers moister habitats. Similar to Green and Forest White-eyes, but slightly paler, and usually separated by its range and preference for drier habitat. Also similar to Southern Yellow White-eye, though usually separated by range; identification in areas of overlap is poorly understood.

分类信息
The northern yellow white-eye formerly included additional subspecies. These were split to create the southern yellow white-eye and the green white-eye based partly on the results of a molecular phylogenic study in 2013. <p>There are seven subspecies:

行为
The northern yellow white-eye has been recorded as a host of the brood parasite green-backed honeybird.<p>The northern yellow white-eye has a diet that mainly consists of insects; caterpillars, aphids and termite alates have all been recorded, supplemented with some fruit including those of figs and the cabbage tree Cussonia spp. It forages among the canopy of trees, gleaning prey from foliage and bark. It is frequently recorded as a member of mixed-species foraging flocks. Also takes nectar from flowers.<p>The nest is a small cup made out of dried grass and small twigs, placed among the foliage in a small tree about 3.5m above the ground and secured with spider web. The clutch of 2-4 eggs is laid from August–January, with most being laid in September–October. Incubation takes about 11–12 days and both sexes share this duty as well as the feeding of the nestling young which fledge after around two weeks.If disturbed in the nest the young will often panic and jump out of the nest.

Rufous-vented Grass Babbler
Laticilla burnesii
Specialized, slender prinia-like babbler. Restricted to lowland grassy riverine plains, where it typically stays low in the vegetation in small flocks, flushing only reluctantly. If seen, note very long tail, white throat, and streaking all over the body. Shy and difficult to see; more readily detected by its bubby, warbling song.
Black Curassow
Crax alector
Large, terrestrial rainforest bird; common and tame where not hunted. Note mostly black plumage, white belly, and yellow base of bill. Walks through forest feeding on arthropods and fallen fruit. When flushed, flies laboriously to low perch and looks back at observer. Frequently seen along roadsides and rivers. Roosts in forest canopy. Males often give low, booming song on moonlit nights.
Rennell Starling
Aplonis insularis
A medium-sized, uniformly black starling with a glossy purplish-bluish sheen and a short tail. Bill is relatively thick and stubby. Arrow-shaped throat feathers are often puffed out. Eye pale orange. Juvenile resembles adult, but dustier in color, with a gray eye. Prefers forest edge; less common inside forest and open areas. Very similar to Singing Starling, but distinguished by pale eye, shorter tail, and lack of dark streaks on belly of juvenile. Song consists of metallic warbling. Common call is a metallic “chink.”
