Canyon towhee


The canyon towhee is a bird of the family Passerellidae.

Taxonomy

The taxonomy of the group of towhees to which this species belongs is debated. At the higher level, some authors place the towhees in the family Fringillidae. Within the genus, there has been dispute about whether the canyon towhee is a distinct species from the California towhee found in coastal regions from Oregon and California in the United States through Baja California in Mexico. At present, molecular genetics seems to have settled this issue in favour of separation of the species.
