Tumbes Sparrow Rhynchospiza stolzmanni Scientific name definitions

Recently returned to the monotypic genus Rhynchospiza, from Aimophila, the Tumbes Sparrow of extreme southwestern Ecuador and adjacent northwestern Peru is the ecological and morphological counterpart of the Chaco-dwelling Stripe-capped Sparrow (Rhynchospiza strigiceps) of southern South America. In plumage, the Tumbes Sparrow differs from its southern counterpart only in the more chestnut ‘shoulder’, although structurally it is larger billed, shorter-tailed, and relatively more bull-headed. The Tumbes Sparrow inhabits scrubby desert country, where it generally is not difficult to see; it primarily forages on the ground, usually alone or in pairs.
