Black-bellied Seedeater

Locally fairly common summer breeder in temperate rainforests of southern Chile and adjacent Argentina; migrates north in March–April to winter in Andes from Bolivia to Venezuela, returning in September–October. Usually seen in flight over forest and edge, circling high or kiting motionless in the wind; rarely seen perched. Note dark head and clean white throat, diagnostic dark “armpits,” and rather flat-winged gliding with wingtips curled up slightly. Compare with immatures of the larger Variable and Rufous-tailed Hawks.

Small, drab tyrannulet found in the lowlands from eastern Guatemala and Belize south to extreme northwestern Colombia. Fairly inconspicuous; usually found as singles or pairs in middle to upper levels of forests, plantations, and second-growth. Typically perches fairly horizontally with the tail held slightly cocked. Feeds mainly on berries. Note the dull whitish eyebrow, small bill, and bright yellow edging on wing feathers.

Rather large, dark, stocky gull-like seabird with big white wing patches (seen in flight). In summer often seen flying over Patagonian steppe or associating with Kelp Gulls at beaches, dumps, river mouths, and lakes near the coast. Also found well offshore, where it chases other birds to steal their food. Usually seen as singles or small groups. Plumage variable, but always with some orange tones—sometimes bright and extensive, sometimes limited to underwing and base of tail. The only skua likely to be seen in Chile and southern Argentina.
