Sumatran Laughingthrush

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.

Immense and imposing owl of dense wet lowland and hill forests. Silver-gray adult is majestic, with a large yellow bill, black eyes, and sweeping sidewards-facing “horns.” Juvenile is much paler, almost white, with shorter tufts. Gives deep echoing hoots. Primarily nocturnal, but will on occasion hunt by day; takes prey as large as small deer.

A long-tailed, shy, ground-feeding species of wet broadleaf forests with dense undergrowth, especially near streams from 700 to 2,000 meters elevation. Dark brown, with white throat that fades into gray-brown chest and belly. Primarily feeds in thick leaf litter. Rather similar to the Eastern Chat-Tanager, which is a bit smaller and has a yellow eyering. This species’ full song is a loud, whistled “tsew, tsee-ew, tsee-ew, tsu, tsu, tsu,” or variations thereon, with final notes given rapidly; often sung in fragments. Songs are more clearly whistled than those of Eastern Chat-Tanager. Call is a “chep.”
