Usambara Thrush
Turdus roehli
A typical thrush with brownish upperparts and paler rufous-and-gray underparts. Also note the darker face, yellow bill, and striped throat. Found in the understory of montane forest and along forest edges. Occasionally bold, but typically quite shy, with only calls betraying its presence in the undergrowth. Abyssinian Thrush is similar, but does not overlap in range. Usambara Thrush gives a typical melodic thrush song, and calls include a "chk-chk" and thin "tseeep" notes.

Pale-eyed Blackbird
Agelasticus xanthophthalmus
Medium-sized blackbird found locally in habitats with wet grass. Shiny black, with a white or light yellow eye and sharply pointed black bill. Giant Cowbird occasionally has a pale eye and may appear similar, but is much larger than Pale-eyed Blackbird; told apart from the similar Velvet-fronted Grackle by its pale eyes, longer, more pointed bill, and shorter tail. Found in wet grasslands and grassy margins of oxbow lakes, where it forages singly, in pairs, or in small groups.

Black-throated Gray Warbler
Setophaga nigrescens
A warbler in grayscale except for a small yellow spot in front of eye. Note black-and-white head with a gray back, white wingbars, and white underparts with dark streaks. Breeds in coniferous forests where they forage for insects; in migration and winter, found in variety of wooded areas. Winters mainly in Mexico.

Half-collared Kingfisher
Alcedo semitorquata
Dark-blue kingfisher of aquatic habitats. Note the dark bill and dark blue face. Found mostly along wooded and forested streams and rivers, though also occurs in some other wetland habitats including freshwater marshes and coastal lagoons. Secretive, solitary, and generally uncommon. Call is a high-pitched “seet.” Larger than Malachite Kingfisher, with a black bill. Similar to juvenile Malachite, which has a dark bill, but Half-collared has a dark face without any orange.
