May hybridize with P. chrysogaster in Ecuador and genetic data indicate that present species may be paraphyletic with respect to latter#R. Race crissalis distinctive for its yellow vs black throat (3), but often with small black maculations, and minor vocal difference#R; no other distinctions apparent. Five subspecies recognized.
