Creamy-rumped Miner
Geositta isabellina
Local in the high Andes of central Chile and adjacent Argentina. Favors open slopes with sandy and gravelly soil, scattered bunch grass and low shrubs, adjacent bogs, and rocky areas. Often in pairs, walking with waddling gait and pumping its tail like most miners. Plumage rather drab and plain sandy overall with diffuse dusky breast streaking and a relatively long and slightly decurved bill. In flight shows a contrasting creamy-white rump. Compare with the similar Rufous-banded and Common Miners.

分布与栖息地
The creamy-rumped miner is found in the Chilean Andes between the Atacama Region and Talca Province and in adjoining Catamarca, San Juan, and Mendoza provinces in Argentina. It inhabits the high Andes, where it favors puna grasslands on generally barren slopes with rocky outcroppings. In elevation it mostly ranges from 3,000 to 5,000 m (9,800 to 16,400 ft) though it also occurs down to 2,000 m (6,600 ft).

Afghan Babbler
Argya huttoni
Slender, dusty-colored babbler with a long tail. Look for its contrasting white throat and streaked crown and back. Found in dry open areas such as semidesert, scrubland, and various edge habitats. Rummages about on the ground in mid-sized to large flocks. Gives a clear, musical, purring series of notes, either ascending or descending, as well as harsher, scratchier calls.
Black Kite
Milvus migrans
Medium-sized, rather nondescript raptor with overall dark plumage. Varies considerably across range, but always note tail fork (can disappear when tail is fully open), and short head and neck. Juvenile averages paler and more contrastingly-marked. Flight style buoyant, gliding and changing direction with ease. Frequently forages in urban areas, rubbish dumps, aquatic habitats, and grassland, but usually avoids heavily forested areas. Sometimes solitary, but also gathers in large flocks on migration and at good feeding areas.
Lizard Buzzard
Kaupifalco monogrammicus
A small, chunky, grayish hawk with a distinctive pale throat spliced by a vertical black throat stripe; has one or two (rarely) broad white bars across the black tail. Occurs in singles or pairs in savanna and is often seen perched in the open, watching for insects, lizards, snakes, and other small vertebrates. Calls a loud shrill “peeee-eeeuuu” or repeated “whuuua-whuuua-whuuaa”. It is shorter-legged and has a more powerful build than most sparrowhawks. Most similar to Gabar Goshawk, both having a broad white rump band in flight, but Lizard Buzzard is distinguished by its distinctive throat pattern, pale tail bands, and pale tail tips.
