Crag Chilia
Ochetorhynchus melanurus
Endemic to rocky hillsides and valleys in central Chile; usually found in foothills with low cliffs or crags where it nests in crevices. Runs well on the ground and clambers in bushes. Moves easily across rock faces with its mostly black tail held slightly cocked or fanned and held low to show its bright rusty tail base. Also note the bright white bib, slender straight bill, and rusty wing patch.
Identification
The crag chilia is 18 to 19 cm (7.1 to 7.5 in) long and weighs 31 to 40 g (1.1 to 1.4 oz). Adults of the nominate subspecies O. m. melanurus have a narrow whitish supercilium, dark brown lores and auriculars, and whitish cheeks. Their upperparts are mostly darkish brown with a rufous rump and uppertail coverts. Their tail is mostly blackish brown with some rufous at the base and outer web of the outermost pair of feathers. Their upperwing coverts are dusky brown and their wings are darkish brown with a wide rufous band. Their throat is whitish, their breast dull smoky grayish, their belly dull brown, and their flanks and undertail coverts rufous. Their iris is brown, their maxilla blackish, their mandible pale gray with a blackish tip, and their legs and feet blackish. Juveniles have pale edges on their back feathers and faint barring on their underparts.<p>Subspecies O. m. atacamae is paler and sandier than the nominate. Its supecilium is whiter and more distinct. Its upperwing coverts are grayish brown, its breast pale grayish with white streaks, and its flanks pale brown. Its bill is shorter and narrower.
Taxonomy
The crag chilia was formerly placed in its own genus, Chilia. It is now placed in genus Ochetorhynchus with the straight-billed earthcreeper (O. ruficaudus), the rock earthcreeper (O. andaecola), and the band-tailed earthcreeper (O. phoenicurus). Two subspecies are recognized, O. m. melanurus and O. m. atacamae.

Range and habitat
The crag chilia is endemic to north-central and central Chile. Subspecies O. m. atacamae is found from Huasco Province in the Atacama Region to the Coquimbo Region. O. m. melanurus is found further south, between San Felipe de Aconcagua Province in the Valparaíso Region and Colchagua Province in the O'Higgins Region.<p>The crag chilia inhabits arid scrublands with shrubby rock hillsides and cliffs with sparse vegetation. There is no consensus on its elevational range. In the non-breeding season it occurs as low as sea level. In the breeding season, different authors place its upper limit between 2,200 and 3,000 m (7,200 and 9,800 ft).

Rufous Potoo
Phyllaemulor bracteatus
Rarely observed, nocturnal bird of lowland rainforest. Considerably smaller than other potoos, and distinguished from them by bright rufous plumage spotted with white. Inhabits middle and upper levels of tall forest, especially in regions with sandy soils, where it sallies from exposed perches for flying insects. Roosts during the day on thin branches and camouflages itself remarkably well by swaying with the breeze as if to mimic a suspended dead leaf. Voice, unlike that of other potoos, is a rapid, descending series of hoots with a bubbling quality, given infrequently and only for short periods. Unlikely to be confused with anything else; plumage recalls Oilbird, but potoo is much smaller and perches vertically.
Greater Prairie-Chicken
Tympanuchus cupido
Plump, chickenlike bird found in grasslands. Body and wings entirely barred brown with paler buffy throat. In spring, males gather at display site and dance to attract females: look for them hunched over with earlike feathers protruding from the head and yellowish-orange skin exposed on the neck. Inconspicuous and difficult to find away from display sites. Separate from Lesser Prairie-Chicken by range; averages slightly darker and larger than Lesser. Darker than Sharp-tailed Grouse with more heavily barred sides and belly; rounded tail.
Mountain Chiffchaff
Phylloscopus sindianus
Very similar to Common Chiffchaff, but distinctly darker brown, and lacks any green or yellow tones including uppertail coverts and fringes to wing feathers. Note the brownish wash to underparts, especially the flanks, the rather contrasting whitish throat, and white eyebrow. Bill and legs distinctly black. Short primary projection. Breeds in forested mountains, valleys, and foothills, including low-stature mixed forest; winters in lower elevation scrub, including acacia and tamarisks. Call similar to Siberian Chiffchaff: a high-pitched, slightly downslurred "Piiu." Song similar to Common Chiffchaff but faster and less “organized.”
