The campo miner (Geositta poeciloptera) is a Vulnerable species of bird in the subfamily Sclerurinae, the leaftossers and miners, of the ovenbird family Furnariidae. It is found in Bolivia and Brazil, and as a vagrant in Paraguay.
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. 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 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... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Campo Miner is recorded against all the birds logged in Serra da Canastra National Park (71 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
