分布与栖息地
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).

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".

Pechora Pipit
Anthus gustavi
Small, graceful ground-dwelling songbird of open areas with patches of low shrubby cover. Strongly streaked overall with a warm brown back and creamy underparts. Noticeably smaller than Richard's and Paddyfield Pipits, slenderer in appearance than American and Red-throated. Bold black-and-white streaks on back distinguish Pechora from other species. Song is an almost insect-like hard buzzing trill with harsher nasal elements. Call is a hard “tsik.”
African Pipit
Anthus cinnamomeus
The default pipit across much of Africa. Brown above and pale below, with a streaked back, well-marked face, and white outer tail feathers. There is considerable geographic variation, from pale and sandy to rich brown and rufous. Found in a variety of open and usually grassy habitats, both near water and in dry areas. Call is a sneezing “tzsht”. Song comprises consecutive series of rattles, given in flight. Very similar to other pipits; some of the key features to look for include the yellow base of the bill, streaked back, and white outer tail feathers.
Sooty Owl
Tyto tenebricosa
Medium-sized dark-gray owl with prominent facial disc and white speckles through the plumage. This handsome species inhabits rainforest, wet eucalypt forest, and surrounding habitats. Its pale feet seem too large for its body. The northern subspecies is smaller and paler. Main calls include a high-pitched "falling-bomb" whistle and insect-like squeaks and trills.
