Bar-winged Weaver
Ploceus angolensis
A localized woodland weaver that has dark brown upperparts, yellow back and rump, obvious white wing bars, and pale underparts suffused with lemon on the belly and flanks. Juvenile is like adult but with a pale crown and bill. Restricted to mature evergreen (Cryptosepalum) dry forests and Miombo woodland where ‘Old Man’s Beard’ Usnea lichen is abundant; singles and pairs sometimes join mixed-species flocks and forage secretively for insects by creeping along branches like a nuthatch or creeper; does not nest colonially. Not very vocal, but occasionally calls a series of high-pitched squeaks, buzzes, and churrs.
识别特征
The weaver is 13cm in length, with dark coloring on the top of the bird's body and light on the bottom. It has dark blackish-brown feathers covering the top of the head and continuing down onto the wings. The wings also contain white tips at the end of each feather, with the female containing much more white. In the middle of the wings, a yellow strip runs down the back of the weaver. The tail resembles the same blackish-brown coloring that is on the head and wings. The chin and belly have a white and yellow wash of color and the females are seen with a whiter coloring. The bill is black, the legs are brown, and the eye iris of the weaver is red.

Southern Hyliota
Hyliota australis
Mid-sized, generic-looking warbler-like bird. Males have a matte black back, a white wing patch, and very pale yellowish underparts. Females are similar, but browner on the back. Found mainly in broadleaf savanna, and locally in humid forest. Usually in pairs or small groups, which will join mixed-species feeding flocks. The quiet vocalizations include chatty calls and trills. Very similar to Yellow-bellied Hyliota. In most of the range, Southern males distinguished by the smaller white patch on the wing, and females by their browner upperparts. In Uganda and Kenya, males are extremely similar, but Southern can still be recognized by its non-glossy black back.
Stripe-faced Wood-Quail
Odontophorus balliviani
Chunky, dark brown quail of cloud forest and elfin forest. Dark brown body is spotted white below; black bandit mask and reddish crown are distinctive. May be found singly, in pairs, or in small groups. Quite secretive, and often goes undetected until flushed suddenly from nearly underfoot. Forages on the ground, climbing over mossy tree roots and scraping aside leaves with its feet to look for small prey. Listen for its low caroling song given at dusk, an often duetted “dwee-put, dwee-put….”
Mussau Triller
Lalage conjuncta
A rather long-tailed and long-winged bird with a short stubby head, similar in proportions to a small cuckooshrike. Plumage distinctively clean-cut in black and white, with mostly black upperside and white underside, broad white wing panels, and a white rump barred black. Belly often tinged with chestnut. Appears dependent on primary undisturbed forest. Often quiet, but voice reportedly includes a nasal “tchow-tchow-de-weet.”
