Wikipedia Abstract

The rock wren (Salpinctes obsoletus) is a small songbird of the wren family native to South America and western North America. It is the only species in the genus Salpinctes. Adults are about 12 cm long. They have grey-brown upperparts with small black and white spots and pale grey underparts with a light brown rump. Additional distinctive features include a light grey line over the eye, a long slightly decurved thin bill, a long barred tail and dark legs. They actively hunt on the ground, around and under objects, probing with their bill as their extraction tool. They mainly eat insects and spiders. Its song is a trill that becomes more varied during the nesting season.
