The orange-eyed thornbird (Phacellodomus erythrophthalmus) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae.

[4] To further complicate matters, for a time in the early twentieth century some authors placed the former two-subspecies red-eyed thornbird alone in genus Drioctistes.

Their throat is dark rufous and the rest of their underparts olivaceous brown that is paler in the center of the belly.

[6][7] The orange-eyed thornbird is found in southeastern Brazil from southern Bahia south to northeastern São Paulo state.

It typically forages singly or in pairs, gleaning prey from vegetation in the forest's thick undergrowth.

[6][7] The orange-eyed thornbird breeds mostly during the austral spring and summer, roughly September to February, but eggs and young have been seen outside this period.

It builds a boot-shaped nest of thorny sticks that can be about 40 cm (1 ft) wide and high, and lines an interior chamber with grasses.

"This species' restriction to narrow band of lowlands of SE Brazil could render it vulnerable in the future.
