Cucarachero Barranquero

Identificación

The canyon wren (Catherpes mexicanus) is a small North American songbird of the wren family Troglodytidae. A non-migratory species, these birds are found throughout western North America in dry, rocky environments such as cliffs, outcrops, and canyons. It is a small bird that is hard to see on its rocky habitat, and is often located by its loud distinctive song. It is currently in a monotypic taxon and is the only species in the genus Catherpes.

Taxonomía

The taxonomy of the species has been altered and debated for many years, with from three to 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.<p>The three generally recognized subspecies are:<p>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.

Distribución y hábitat

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 southwest Texas. Similar to the rock wren in habitat, the canyon wren prefers steeper rocky environments, particularly in arid landscapes and deep canyons and terrain (sometimes including buildings, woodpiles, and rock fences). This species regularly uses riparian areas for foraging and has bred away from rocky substrate.
