Firewood-gatherer

The firewood-gatherer (Anumbius annumbi) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina, Brazil, Paraguay, and Uruguay.

The firewood-gatherer is 18 to 20 cm (7.1 to 7.9 in) long and weighs 27 to 45 g (0.95 to 1.6 oz). It is an unusual furnariid that somewhat resembles a pipit. The sexes have the same plumage. Adults have a wide whitish supercilium and a medium brownish stripe behind the eye on an otherwise light brownish to grayish brown face. Their forehead is dull rufous and their crown dull brown or sandy brown. Their back is dull brown, their rump dull pale brown, and their uppertail coverts dark brownish with lighter brownish edges. Their crown has narrow blackish streaks that almost disappear on the hindneck and upper back but then become longer and wider on the lower back. Their wings are mostly dull brown with some darker centers on the coverts and darker tips on the flight feathers. Their tail's central pair of feathers are pointed and dark brownish; the rest are less pointed and blackish brown with varying amounts of white near their ends. Their throat is white with a line of black speckles on its side. Their upper breast is a slightly reddish light brown and whitish buff with blurry streaks that fade by the pale buffy belly and undertail coverts. Their flanks are darker sandy brown. Their iris is brown to reddish, their maxilla dull brownish, their mandible gray to light gray with a dark tip, and their legs and feet gray to greenish gray to creamy gray. Juveniles have no rufous on their forehead, an ochraceous throat, and less distinct streaks on the upperparts and darker underparts than adults.
