Sometimes considered conspecific with N. griseus; separation based on distinctly different voices. In Costa Rica, where both occur, there appear to be no constant morphological characters to distinguish the two vocal types. Type specimen of race costaricensis comes from a region in C Costa Rica where presumed that only the jamaicensis vocal type occurs, hence its placement within present species; most specimens previously attributed to costaricensis, however, including those from Caribbean slope of Nicaragua, probably represent the N. griseus vocal type. Otherwise, mainland races lambi and costaricensis doubtfully valid, probably representing extremes in clinal variation, and may be better synonymized with mexicanus#R. Race abbotti has been proposed as a separate species on grounds of clearly longer song, but number of individuals sampled unspecified. Thorough taxonomic revision needed. Five subspecies currently recognized.

Subspecies and Distribution
  • N. j. lambi J. Davis, 1959 – Pacific slope of W Mexico.
  • N. j. mexicanus Nelson, 1900 – E & S Mexico S to El Salvador and Honduras, including Roatán I (off N Honduras).
  • N. j. costaricensis Ridgway, 1912 – Pacific slope of N & C Costa Rica, possibly also W Nicaragua.
  • N. j. jamaicensis (J. F. Gmelin, 1789) – Jamaica.
  • N. j. abbotti Richmond, 1917 – Hispaniola and Gonâve I.
  • Presence in W Cuba (subspecies undetermined) now confirmed by various observations#R.
