Wren, Rock bird picturesROCK WREN
715. Salpinctes obsoletus. 5.75 inches
Upper parts stone color, specked with black; rump brownish; underparts whitish with indistinct streaks on the throat.
A common bird on the dry, rocky foothills of the Rockies and westward.
They are well named, for their favorite places are among the rocks, where they are always busily engaged in hunting insects or spiders in the crevices. Owing to their colors and their habits of slinking away behind the rocks they are quite difficult to see, but their sweet song is always heard if any of the birds are in the vicinity.
Song. - Very sweet and varied, almost canary-like, but impossible to describe; call, a harsh grating note.
Nest. - Of sticks, weeds, grasses, etc., concealed in crevices among the rocks; the five or six eggs are white, sparingly specked with redddish brown (.72 x .54).
Range. - Western U.S. from the western border of the Plains to the Pacific, north to Dakota and British Columbia; winters from southwestern U.S. southward.
