Central American races may be a separate species from the two South American ones, as suggested by strong difference between dawn song of nominate (no recordings of ultima found) vs that of pudica and browni, a repeated “cheeh-rr-eéh...chee-rr-eéh...chee-rr-eéh...” (an overslurred whistle followed by rising burry part and a higher-pitched second overslurred note) vs “whéerr-heeh” and “whéerr-heeh-brrrr” in various combinations (an overslurred note with burry descending leg followed by a well-separated underslurred note, sometimes with gurgling ending rattle)#R; morphologically all taxa very similar, but South American two may average smaller-billed. Four subspecies recognized.
