Genetic data#R suggest possible sister relationship with T. rufitorques, with behavioural and vocal similarities. Previously considered conspecific with T. confinis, which see. Geographical variation rather clinal. Proposed race aleucus (from Texas) considered indistinguishable from propinquus. Six subspecies recognized.
