The canyon wren (Catherpes mexicanus) is a small North American songbird of the wren family Troglodytidae. It is resident throughout its range and is generally found in arid, rocky cliffs, outcrops and canyons. It is a small bird that is hard to see on its rocky habitat; however, it can be heard throughout the canyons by its distinctive loud and beautiful song. It is currently in a monotypic taxon and is the only species in the genus Catherpes.
The taxonomy of the species has been altered and debated for many years with between three and eleven subspecies being proposed at various times. Generally, three subspecies are recognized. Originally in the genus Thryothorus, it was moved into the genus Salpinctes along with the rock wren (Salpinctes obsoletus), where some researchers still place it; however, generally now the species is in the only species in the genus Catherpes.
The three generally recognized subspecies are:
These subspecies are distinguished by the bill of C. m. albifrons which is generally longer than that of C. m. mexicanus, and its plumage paler, with upperparts more grayish brown, with narrower black bars on tail. In C. m. conspersus the plumage is paler and it is smaller than C. m. mexicanus.
Resident, although individuals may make short seasonal movements. It ranges from southern British Columbia in the Okanagan Valley and western and southern Idaho and southern Montana south through central Wyoming, Colorado throughout much of Mexico south to western Chiapas. It occurs east to southwest Oklahoma and in the Edwards Plateau of west-central Texas. Disjunct populations occur in the Black Hills of southwest South Dakota, northeast Wyoming and southeast Montana. During the winter season the distribution is generally the same, however; concentrations may occur in the Chihuahuan Desert of southeast Texas.
