Анумбі темнохвостий Ochetorhynchus phoenicurus

Distinctive little bird of shrub-steppe in Patagonia, sometimes seen in rather open and overgrazed areas with only a few bushes, in which its bulky stick nest is built. Found singly or pairs, usually running well on the ground with tail cocked up or perched on a bush. As well as shape and behavior, note the narrow whitish eyebrow, streaky breast, and black tail with a dark rusty band at the base.
