Not only that, but some suggest that the bronze-tailed barbthroat ("T. n. loehkeni") should also be thought a valid species and have the doubtful Christina's barbthroat ("T. n. christinae") as a subspecies. Freire's Sooty barbthroat (T. n. freirei) is average between the sooty and bronze-tailed barbthroats however, and thus its status needs to be more clear before the problem is fixed.
