Diuca Finch
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.
分类信息
The diuca finch was formally described in 1782 by the Chilean naturalist Juan Ignacio Molina under the binomial name Fringilla diuca. The specific epithet is from the Araucano names Diuca or Siuca for this species. With the transfer of the glacier finch (formerly white-winged diuca finch) to Idiopsar or Chionodacryon, the diuca finch is now the only member of the genus Diuca, which was introduced in 1850 by the German naturalist Ludwig Reichenbach.<p>Four subspecies are recognised:

Gray-backed Hawk
Pseudastur occidentalis
An endangered raptor found only in western Ecuador and immediately adjacent parts of Peru. It has white underparts, dark gray back and wings, and gray streaks on the head. Its tail is white with a thick black band near the tip that is especially evident in flight. Restricted to areas where extensive forest cover remains. Prefers dry and semi-humid areas; not normally present in the wetter forests of northwestern Ecuador, but may occasionally wander into them.
Curl-crested Manucode
Manucodia comrii
A large, crow-sized bird of wooded habitats on the southeast islands. Black overall with blue iridescence on the shoulder, and purple on the flight feathers and tail. Note the distinctive, dorsally-flattened tail with folded tips and feathered bulge on the head. The only other manucode in range is Trumpet Manucode, but Curl-crested lacks the loose feathers around the neck. Similar size to Torresian Crow but Curl-crested has a dark eye. Song, a remarkable, descending series of hollow notes given while tilting backwards, then rolling its whole body up and over.
Plain-winged Antshrike
Thamnophilus schistaceus
Even-colored antshrike of forest under- and midstory. Often travels with mixed-species flocks. Males are plain gray; females are tawny with olive underparts. Females have a more contrasting reddish cap than other female antshrikes. Heard more often than seen; listen for a series of accelerating “awh” notes terminating in a punctuated down-slurred note.
