Origin of type specimen unclear, leading to confusion over correct allocation of nominate subspecies autumnalis; S race has been labelled discolor, with N race then as nominate#R, but re-examination of the literature indicates that autumnalis should be applied to S population, with N population then named fulgens#R#R#R. N race is distinctive, lacking grey lower breast to hindcollar, but other differences apparently minor. Races intergrade in Panama. Two subspecies recognized.

Subspecies and Distribution
  • D. a. fulgens Friedmann, 1947 – Northern Black-bellied Whistling-duck – SE Arizona and SE Texas (S USA) S to C Panama.
  • D. a. autumnalis (Linnaeus, 1758) – Southern Black-bellied Whistling-duck – C Panama to South America, S to Ecuador and N Peru in the W and N Argentina in the E.
