See P. bairdii. Races weakly differentiated; proposed race †houstonensis (based on a now vanished breeding population from Houston, in SE Texas), probably inseparable from nominate, but reconsideration of evidence worthwhile. Species sometimes treated as monotypic. Two subspecies provisionally recognized.
