Masked Lark

Dull gray-brown flowerpecker with streaked white underparts. Unremarkable; bill isn’t all that noticeably thick, but combination of pale vent, striped throat, and (in some subspecies) strongly streaked underparts serve to identify this wide-ranging and variable species. Like many other flowerpeckers, often associated with mistletoe, but can be found in a variety of forest types and elevations. Often heard giving a hard, slightly wet “tsip!”

A plain gray-brown chat that has rusty ear patches and a rufous rump and outer tail feathers that outline an inverted black “T” pattern on the tail. The juvenile is spotted and scaled buff. The species occurs in a broad range of habitats, but favors rocky areas, gullies, outcrops, and buildings, where it often perches conspicuously. It drops to the ground or into a bush to feed on invertebrates and frequently flicks both wings simultaneously and lifts its tail. The similar Sickle-winged Chat has longer legs, a more conspicuous eye-ring, a creamy-orange rump, and a different tail pattern; Brown-tailed Chat also has a different tail pattern.

Common summer resident in the Andes of central Chile and adjacent Argentina; migrates north in winter. Found on rocky and stony slopes with scrubby bushes, gravel plains, bogs, and lakeshores; often the commonest ground-tyrant, associating readily with other species in migrant flocks. Best identified by brownish cast to back (not pure gray), diffuse rusty nape patch, and relatively distinct whitish eyebrow; sometimes very confiding.
