The rufous-breasted leaftosser (Sclerurus scansor) is a species of bird in the subfamily Sclerurinae, the leaftossers and miners, of the ovenbird family Furnariidae. It is found in Argentina, Brazil, and Paraguay. The rufous-breasted leaftosser's taxonomy is unsettled. BirdLife International's Handbook of the Birds of the World (HBW) treats the taxa as two separate species, the rufous-breasted leaftosser sensu stricto and the Ceara leaftosser S. cearensis. The South American Classification Committee of the American Ornithological Society also does not recognize the "Ceara leaftosser" but does not address subspecies within the rufous-breasted.
The rufous-breasted and grey-throated leaftosser (S. albigularis) are sister species. This article follows the one species, two-subspecies model. The rufous-breasted leaftosser is one of the larger members of genus Sclerurus. It is 17.5 to 20.1 cm (6.9 to 7.9 in) long and weighs 30 to 41 g (1.1 to 1.4 oz). The sexes... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Rufous-breasted Leaftosser is recorded against all the birds logged in Serra dos Órgãos National Park (132 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.
