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.

Northern Emerald Toucanet
Aulacorhynchus prasinus
Like other toucans, the northern emerald toucanet is brightly marked and has a large bill. Adults are 29 to 37 cm (11 to 15 in) long and weigh about 150 to 240 g (5.3 to 8.5 oz). The sexes are alike in appearance although the female generally is smaller and shorter-billed. Their bill has a black mandible, a yellow maxilla with a black patch near the nares, and a white vertical strip at its base. All subspecies have plumage that is mainly green like that of other members of genus Aulacorhynchus, and is somewhat lighter below than above.
