HBW diagnosed the form ocypetes on basis of “longer tail and wings than other races and paler grey chin and throat, brown forehead and pale-fringed superciliary line”, and it was later elevated to species status on account of “uppertail-coverts... completely covering tail, which is longer than in Short-tailed... wings notably long and bowed, very different from Short-tailed...”, with differences in voice (well-enunciated series of “chip-chip-chip...” vs very fast, high, run-together twitters#R), but subsequently wings described as shorter and calls similar#R. Material in AMNH suggests an overlap in supposedly diagnostic plumage features; therefore, pending further clarification, ocypetes is retained as a subspecies. Four subspecies recognized.
