Striated Thornbill

Fairly common in the Andes of central Chile and adjacent Argentina; seen readily at ski resorts, around villages, on bogs, and on stony and grassy slopes. Often in flocks, associates readily with other seed-eating birds. Feeds mainly on the ground, but sings from prominent perches such as a rock or building. Not appreciably larger than other yellow-finches, but no similar species in most of range. May overlap in winter locally with Greenish Yellow-Finch, which has shorter wings and a shorter bill, and male never is as bright golden as the Greater Yellow-Finch.

Small (and small-billed) shrike-tyrant of open country in the southern cone, more reminiscent of a monjita than a shrike-tyrant. Note small bill, lacking terminal hook. Breeds in northern Patagonia and the southern Monte desert, as well as the Sierra de Comenchingones in central Argentina. Disperses northward and upslope into W Paraguay and SE Bolivia during the austral winter. Prefers exposed perches in low vegetation, wires, and shrubs.

A small green-backed forest cuckoo of West and Central Africa. Males have a distinctive bright yellow throat and a brown-and-black barred belly, while females lack the yellow throat and have a brown-and-black barred face, throat, and breast. Can be located by its distinctive song, which is a series of up to 10 or more rapidly delivered clear whistles that speed up before quickly fading. Alternate call is an often overlooked “dwuit-tew” or “wait here.” Usually outnumbered by African Emerald Cuckoo, in which males have yellow bellies and green heads and females have more of a black-and-white barred appearance.
