Borba, Rio Madeira, Brazil.
Usually considered conspecific with R. tucanus, but differs in having distal two-thirds of bill laterally black vs deep red (3); uppertail-coverts more golden, tips sometimes orange or red (2); somewhat larger size (at least 1); slightly lower-pitched and possibly more guttural song (but this may be simply a function of larger size; ns); broad hybrid zone exists, with variably intermediate populations in Brazil from R Solimões and Rondônia E to Pará, and from S Venezuela to Mato Grosso and Goiás (1). Race inca sometimes merged with nominate, with which it intergrades, but it has been suggested that it represents relict semi-stabilized hybrid population#R between present species and tucanus, although uppertail-coverts actually redder; in the past, was at times considered alternatively a distinct species. Two subspecies recognized.
