no locality = Buenavista, Colombia.
Fairly close relative of R. tucanus and R. cuvieri, these three constituting the so-called “yelping group” of toucans. Long considered to include R. brevis as race, but they are now generally accepted as distinct species, with different vocalizations. Race swainsonii often treated as a distinct species, but resembles nominate in behaviour, voice and morphology (they apparently interbred in former contact zone in lower Cauca Valley, in Colombia); moreover, smaller race abbreviatus seems to represent an intermediate form, having bill like that of nominate but facial skin like that of swainsonii; species treatment of swainsonii presumably based largely on its sympatry with R. brevis when latter thought to belong within present species. Other described forms include innominatus from Colombia, a synonym of nominate ambiguus, and tocard and tocardus, which are synonyms of swainsonii. Three subspecies recognized.
