ジュウカチョウ Diuca diuca

Distinctive and attractive “finch” (actually a tanager); common in lowlands and foothills of central Chile and Argentina, uncommon south into Patagonia. Feeds on ground and often seen on gravel roadsides, lawns, and stony slopes, where it moves with a distinctive shuffling gait. Often in small flocks, associating readily with other seed-eating birds. Big white tail corners show in flight and when flushed off roadsides. Song of fairly loud, bright chips is given from perch such as atop a bush or wire.
