|Spotted towhee (Pipilo maculatus)|
Towhees typically have longer tails than other emberizids. Most species tend to avoid humans, so they are not well known, though the eastern towhee P. erythrophthalmus is bolder. This species, and some others, may be seen in urban parks and gardens.
There has been considerable debate over the taxonomy of the towhees in recent years. Two species complexes have been identified, the rufous-sided complex (involving Pipilo erythrophthalmus, P. maculatus, P. socorroensis, P. ocai and P. chlorurus), and the brown towhee complex (involving Melozone crissalis, M. fuscus, M. aberti and M. albicollis). The distinction of species within these is uncertain and opinions have differed over the years. Modern authorities distinguish all four species in the brown towhee complex, though M. fuscus and M. crissalis were formerly treated as a single species. Hybrids are frequent between some of the species, particularly between the Mexican races of P. maculatus ("olive-backed towhee", P. m. macronyx) and P. ocai.
