The East Amazonian fire-eye (Pyriglena leuconota) is an insectivorous bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds".

[1] The East Amazonian fire-eye was described and illustrated by the German naturalist Johann Baptist von Spix in 1824 and given the binomial name Myothera leuconota.

The International Ornithological Congress, the Clements taxonomy, and the South American Classification Committee of the American Ornithological Society treat it as a species with these three subspecies:[1][4][5] However, BirdLife International's Handbook of the Birds of the World (HBW) treats the three taxa as subspecies of what it calls the white-backed fire-eye, with the binomial Pyriglena leuconata sensu lato.

Males of all three subspecies are mostly glossy black with a partially hidden white patch between their scapulars and blackish gray underwing coverts.

Females of the nominate subspecies P. l. leuconota have dark reddish brown crown, upperparts, and wings with a partially hidden white interscapular patch.

Their diet includes a wide variety insects (e.g. orthopterans, beetles, ants, wasps, and adult and larval moths and butterflies), other arthropods such as spiders and centipedes, and small lizards up to about 11 cm (4.3 in) long.

The nest is an "oven" made of dried leaves and twigs with club mosses and grass roots mixed in, and hidden among vegetation on the ground.

The East Amazonian fire-eye's song is a "rapid, slightly rising, then descending series of very high, staccato 'weet---' notes" that lasts about two seconds.

[9] The IUCN follows HBW taxonomy and so has not separately assessed the western, Tapajos, and East Amazonian fire-eyes.

[10] It is considered fairly common throughout its range and "is more capable than many forest birds of persisting in older second growth".
