River Warbler

Small bunting with an attractive contrasting head pattern: black crown with red-brown central stripe and pale eyering. Rufous cheeks bordered by narrow black lines framing the eyes. In the nonbreeding season, less bright overall but white wingbars more conspicuous. Breeds in taiga forests and open tundra with scattered birches and willows, often near water; song is a pleasant two- or three-part series of bright, buzzy warbled notes. Winters in various open habitats, including fields, brushy roadside ditches, and gardens. Often attracts attention by its sharp clicking "zick" call note.

A tiny purplish-blue bird with a chestnut cap, a soft pink belly, and a pale brow that is not always prominent, and more often grayish than white. Lacks the pale head of Crested Tit-Warbler. Breeds in high-altitude forests and scrub, but descends into foothills in the winter. Usually seen singly, in small flocks, or as a part of mixed flocks. Gives high crisp-sounding notes, usually in pairs.

A small though long-tailed hornbill that is frequently encountered as it flies singly or in groups over the canopy, between forest gaps, and over road cuts. Distinctive, with a bright white belly and a black head, body, wings, and tail, giving it a bicolored appearance. Similar to West African Pied Hornbill, but usually separated by range, and the sides of the tail are mostly white (instead of having white corners), and the bill is pale yellow with a dark red (rather than black) tip. Calls are a series of high-pitched whistles: “heu heu heu heu.”
