Sage Thrasher
Oreoscoptes montanus
The smallest thrasher; crisp black streaking on underparts unlike most other western thrashers. Grayish brown with buffy wash on belly and sides and thin white wingbars. Long tail. Small, slightly downcurved bill. In flight, look for white corners on tail. True to its name, shows a strong affinity for sagebrush. Singing males perch conspicuously, otherwise furtive, running around on the ground in search of insects. Song is a long, loose series of musical chirps and whistles.

保护状况
These birds have declined in some areas where sagebrush has been removed but are still common where suitable habitat remains. The continued decline of sagebrush habitats in western North America is cause for alarm for this and other sagebrush dependent species.

Mountain Caracara
Daptrius megalopterus
Uncommon to fairly common in the Andes, where its range does not overlap with closely related species to the north and south. Favors open habitats from puna plains to bleak desert and ski lodges, often with rocky cliffs nearby. Sails, soars, and tumbles easily on updrafts. Adult is strikingly patterned black-and-white with a black head and breast and a bold white tail tip. Juvenile is rather similar to smaller Chimango Caracara of lowlands, but distinguished by black (not pale) bill.
Streaked Spiderhunter
Arachnothera magna
A large and noisy inhabitant of tropical and subtropical hill forests. Distinctive in its range; a large spiderhunter with a long, curved black bill and black streaking all over its yellow-green upperparts and lighter yellow underparts. Gleans invertebrates from foliage, but also hovers around and probes into flowers for nectar. Often moves with mixed flocks. Calls frequently, giving a loud, decisive-sounding “chitick, chitick!”.
Chestnut-cheeked Starling
Agropsar philippensis
Adult male glossy purple above, white below, with chestnut cheek patch, green wings, and white wing patch most noticeable in flight. Female gray-brown above, white below, and lacks the cheek patch; similar to a female Daurian Starling but less colorful, wing less marked. Prefers open areas with stands of tall vegetation. Regularly flocks with other starlings.
