Slaty Vireo

Very like Crested Lark, with which it often occurs. Best told by bill shape, which is shorter and stubbier, with a convex lower mandible. Crest is also shorter and more fanlike; rump is more contrasting and rusty-tinged. Breast streaks heavier and more contrasting than Crested Lark. Found in stony and sandy areas with scattered bushes in Iberia, North Africa and East Africa. More likely to perch up on bushes than Crested Lark. Song is a musical jumble of twitters, warbles, trills, and slurred notes.

Rather large, chunky tanager endemic to northwestern Colombia. Unlikely to be mistaken. Male isall sooty gray with striking red throat and crest. Female is similar to male but slightly duller. Occurs in the lowlands up to around 1,100 m. Typically seen in pairs or small groups in the understory of forest, often near water. Frequently follows mixed-species flocks.

Small scrubwren with white eyebrow and pale iris. Has a dark face with a clear white eyebrow and chin stripe. Primarily olive-brown with a black-and-white shoulder patch and paler front. Chin is white with varying levels of black streaking depending on the location. This species is widespread across eastern coastal Australia, but is absent in the northern areas. Western edge of its expected distribution is the Mt Lofty Ranges east of Adelaide. Found in a wide range of habitats but typically only present where there is reasonably thick undergrowth. It often makes a grumpy buzzing call but also sings a clear musical song.
