White-winged Lark

Small vireo-like bird with a brownish cap. Olive-green above and grayish-white below. An inhabitant of savanna woodlands, white sand forests, and seasonally flooded forests, where it forages actively at middle levels and sometimes accompanies mixed-species flocks. The song is a series of downslurred whistles: "seeeeearn, seeeeearn."

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.

Large, glossy black crow. Adult is easily passed off as another crow species unless you see the diagnostic pale patch at the base of the bill. Juvenile lacks a pale bill base and is very similar to Carrion Crow, but bill is a little more tapered; pale bill base develops late in its first winter. Inhabits farmland and other semiopen areas with hedges and groups of tall trees, where nests in rookeries. Forages on ground, usually in flocks, and associates readily with crows and jackdaws. Rook calls are higher pitched and less rolling than other crow calls.
