The freckle-breasted thornbird (Phacellodomus striaticollis) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina, Brazil, Uruguay, and possibly Paraguay. The freckle-breasted thornbird was first described by Alcide d'Orbigny and Frédéric de Lafresnaye in 1838, from Uruguay.
The freckle-breasted thornbird is monotypic. However, what is now the spot-breasted thornbird (P. maculipectus) was long considered a subspecies of it, but they are not closely related. The freckle-breasted and greater thornbird (P. ruber) are sister species.
The spot-breasted thornbird is 16 to 20 cm (6.3 to 7.9 in) long and weighs about 24 to 27 g (0.85 to 0.95 oz). It is a medium-sized thornbird. The sexes have the same plumage. Adults have an indistinct light brownish supercilium that extends beyond the eye and a very narrow dark brown stripe behind the eye on an otherwise light brownish face.

Their wings are mostly shades of brown with darker brown primary... Wikipedia →

GBIF citizen-science records
