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).

行为
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".

Forest Penduline-Tit
Anthoscopus flavifrons
Tiny, drab bird with a sharp bill, a dull olive-green back, and buffy yellow underparts and forehead. Found in lowland rainforest, secondary forest, and sometimes plantations, usually in the canopy. Uncommon and inconspicuous, in pairs or small flocks. Similar to Yellow Penduline-Tit, but much duller and found in different habitat. Could be confused with Tit-Hylia, but duller overall, without streaking on the head and breast. Could also be confused with some dull sunbirds, but has a shorter, deeper-based, and sharper bill. The vocalizations are very high-pitched “sit” notes that are easily missed.
Indochinese Bushlark
Plocealauda erythrocephala
Short-tailed lark with a streaky brown back and inky black streaks on the chest. General coloration very similar to various other larks, but the shorter tail Indochinese Bushlark separates it from Australasian Bushlark and migrant or vagrant larks. Song is a series of clear cricket-like trills, given from the ground, a perch, or the air. Calls include similar trilling, as well as whistles. Inhabits open dry land such as fields and grasslands with small trees and bushes dotted around. Unlike skylarks, readily perches on trees and bushes.
Black Partridge
Melanoperdix niger
Infrequently-encountered small gamebird. Male is uniquely glossy-black all over, while the female is predominantly chestnut-brown with a pale lower belly. Both sexes have an odd, heavy bill somewhat reminiscent of a finch or parrot. Inhabits lowland and foothill forest, often favoring wetter areas. Forages on the ground, singly or in pairs. Generally quiet.
