Campo Miner
Geositta poeciloptera
Small terrestrial ovenbird with a short tail. Brownish overall, paler below, with a whitish eyebrow and speckled breast. In flight, exhibits a bright rusty pattern on the wings and tail. Found in grassland areas and in open savanna, preferring recently burned areas, where it typically forages in pairs, walking on the ground.
Identification
The campo miner is a small member of its genus. It is 11 to 12 cm (4.3 to 4.7 in) long and weighs 17 to 19 g (0.60 to 0.67 oz). The sexes are alike. It has a dull rufescent brown face with a buff supercilium. It is dull grayish brown from its crown to its rump; the crown has vague brown spots and its rump and uppertail coverts have a rufescent tinge. Its tail is short; its feathers are rufous with a blackish brown band near the end. Its wing coverts are dark brownish with paler edges. Its axillaries ("wing pits") are cinnamon. Its flight feathers are blackish with a wide chestnut-rufous band that shows in flight. Its throat is whitish, its upper breast dull buff with brown flecks, its lower breast and belly whitish, and its flanks and undertail coverts pale rufous. Its iris is brown, its shortish bill is dark horn or blackish with a pale horn or pinkish gray base to the mandible, and its legs and feet are pale brown to pale gray or even dull pinkish.
Taxonomy
The campo miner was originally placed alone in genus Geobates and has sometimes been treated there since, but genetic data place it firmly in Geositta. It is monotypic.

Range and habitat
The campo miner is found in south-central Brazil, in an area roughly bounded by the states of Mato Grosso, Bahia, and Paraná, and in northeastern Santa Cruz Department in Bolivia. There is also at least one record in Paraguay. It inhabits campo grasslands and cerrado, open landscapes with at most scattered trees. It favors recently burned areas, especially for breeding. In elevation it ranges between 500 and 1,250 m (1,600 and 4,100 ft).

Behavior
The campo miner is non-migratory, but makes local movements among areas of suitable habitat.<p>The campo miner forages singly or in pairs. It gleans food from the ground while hopping, not walking. Its diet is mostly arthropods; known items include Hymenoptera, Coleoptera, Mantidae, and spiders.<p>The campo miner's breeding season has not been fully documented but includes at least September and October. The three known nests were in side chambers in armadillo burrows; the chambers were lined with dead grass and hair. The one clutch was of three eggs.<p>The campo miner's display flight song is a "high, level, hurried, rolling 'turruturrut---' " that lasts 15 to 20 seconds. Its flight call is "pit-pit".

Sri Lanka Blue-Magpie
Urocissa ornata
A large, long-tailed blue bird with a white-tipped tail, and chestnut hood and wings. Inhabits humid forest from lowlands to hills, where it often accompanies mixed canopy flocks, either singly or in small groups. There are no other large, long-tailed blue birds in its range. A noisy species. Sounds typically a series of high-pitched, piercing “clink” calls, as well as some rasping “krak” notes often given in a sequence.
Polynesian Starling
Aplonis tabuensis
A small to medium-sized starling, dark above and pale below with long buffy or gray streaks. Note the distinctive pale or white wing panel. Usually has a pale eye, but eye is dark in eastern Fiji and south Tonga. Common in all habitats. Samoan Starling is much larger and more uniformly dark, lacking a pale wing panel. Rusty-winged Starling is paler above with a dark eye and no pale wing panel. Polynesian’s most common call is a high-pitched repetitive “twee-wee.”
Nariño Tapaculo
Scytalopus vicinior
A standard Scytalopus tapaculo: plain dark gray with browner flanks and rump. Acts like a mouse, scurrying around on or near the ground within montane forest. Very difficult to see. Restricted range on the west slope of the Andes in Colombia and Ecuador. Occurs from around 1,250–2,000 m, which is higher than Choco Tapaculo but lower than Spillmann’s Tapaculo (but some overlap). Far more often heard than seen. Listen for fairly rapid trill with distinct notes; notably slower than Spillmann’s.
