Rock Wren Salpinctes obsoletus

True to its name, prefers rocky areas, especially rocky slopes. Often perches conspicuously and bobs up and down. Pale grayish wren with whitish throat, buffy sides, and long, slightly decurved bill. Tiny speckles on back and wings like grains of sand. Undertail coverts barred black and white. Paler overall than Canyon Wren with a pale, buffy belly. Listen for its ringing vocalization. Sexes alike.
