Aulacorhynchus haematopygus
The crimson-rumped toucanet is 40 to 45 cm (16 to 18 in) long. The nominate subspecies weighs 200 to 232 g (7.1 to 8.2 oz) and A. h. sexnotatus 141 to 200 g (5.0 to 7.1 oz).

Groove-billed Toucanet
Aulacorhynchus sulcatus
The groove-billed toucanet is 33 to 37 cm (13 to 15 in) long and weighs 130 to 200 g (4.6 to 7.1 oz). Its grooved culmen and mandible give it its English name. In the nominate subspecies and A. s. erythrognathus, most of the bill is wine-red to brown-red with a diagonal black stripe on the mandible. The nominate's bill also has a vertical white stripe at its base. In A. s. calorhynchus the bill is mostly yellow with a reduced amount of black, some orange-red at the base of the mandible, and a white stripe like the nominate's. Voice: The groove-billed toucanet's song is "barking-growling notes or croaks...wik-wik- to waak-waak-", sometimes sung in duet. Male's voices are lower pitched than female's. A. s. erythrognathus' song sounds similar to those of the other subspecies but is apparently faster.
