Yellow-streaked Warbler

A tiny, brightly colored bird with a sharp bill. The back is olive-green, the wing blackish with white fringes, and the underparts yellow. Local and uncommon in savanna, ranging from moist Guinea savanna to dry thorn savanna. Usually in pairs or small flocks. Similar to Sennar and Forest Penduline-Tits, but much brighter: yellow rather than buffy below, and with white edges on the wing feathers. Vocalizations include a series of whistles in an up-and-down pattern and a quick series of buzzy notes. 

Medium-sized, slim shrike patterned in dark gray, black, and white. The male has completely white underparts, while the female has a rufous flank patch. There are large white slashes across the shoulders. Found along forest edge and in forest clearings, lush woodland, cultivations, and gardens. Usually seen singly or in pairs. The song is a slow, highly varied series of many different types of notes, and can include imitations of other birds. Similar to Northern Fiscal, but has a gray crown and back. Distinguished from other black-masked, gray-backed shrikes by the lack of a white nick on the wing.

Unusual dark greenbul with upright posture that does strongly resemble a honeyguide. Males have a white eye and females a dark one. Both sexes show a large white patch in the outer tail. Found in the upper portions of lowland forest. Usually in pairs or small groups. Most often detected by call: a slow series of mewing whistles. Similar to Sjöstedt's Greenbul, but has darker gray underparts, and male further distinguished by its pale eye. Distinguished from honeyguides by its different shape, especially the longer tail. Flight is direct, unlike undulating flight of a honeyguide.
