Moluccan Myzomela

Striking tanager of open woodland, consisting of two relatively distinctive subspecies. Distinguished from other warbling-finches in range by its black breast band. Nominate torquatus is a resident of the southern Bolivian Andes, especially open scrub and cactus forest of the dry valleys. Migratory pectoralis shows a thicker breast band and darker undertail coverts, and breeds in the Pampas, Monte, and northern Chaco dry forests in north central Argentina, dispersing north to lowlands of W Paraguay and SE Bolivia.

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.

A very slender gray-brown swift with a long, deeply forked tail that is often held closed, making it look needle-like and pointed. The erratic flight pattern, with frequent direction changes and rapid wingbeats on long, scythe-shaped wings, is distinctive. Less gregarious than other swifts; usually found in pairs or small flocks, and association with other swallows and swifts is usually only fleeting. Forages over a wide variety of habitats with palms, including savanna, coastal scrub, towns, villages, cultivated areas, forest edge, and clearings, from sea level up to 1100 meters of elevation, preferring lowlands. Nests and roosts in palms, especially Hyphaene, Bismarckia, and coconut palms. Gives a high-pitched, metallic “tre-tit-tit-tit-tit-tit-tit-tit” call, solitarily or in unison with others. Separated from other swifts by its longer and thinner tail. Further separated from the larger Madagascar Swift by its much weaker and more fluttering flight.
