Austral canastero

The austral canastero (Asthenes anthoides) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina and Chile.

The austral canastero is 15.5 to 16.5 cm (6.1 to 6.5 in) long and weighs 21 to 23 g (0.74 to 0.81 oz). It is the southernmost canastero, and one of several streaked canasteros that have drab plumages with dark stripes on their upperparts. It has a shorter tail than many other canasteros. The sexes have the same plumage, but there is much individual variation. Adults have a whitish or pale buff supercilium and dark dusky lores on an otherwise sandy brownish face. Their crown, back, and rump are sandy brown with conspicuous blackish streaks. Their wings are brownish with cinnamon to brown coverts and dark dusky flight feathers with pale tawny brown bases on the primaries. Their tail's central pair of feathers are dark olive-brownish with a dark brownish streak along the shaft, the next pair are mostly dusky, and the rest are mostly dusky with whitish ochre tips. Their chin is whitish, sometimes with a pale orange-rufous patch. Their throat, breast, and belly are whitish or very pale sandy brown with some blackish streaks on the sides of the breast and the flanks. Their iris is black, their bill black with a whitish base to the mandible, and their legs and feet pink to dusky gray. Juveniles have blackish-brown streaks on their breast and sides.
