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.

All subspecies have plumage that is mainly green like that of other members of genus Aulacorhynchus, and is somewhat lighter below than above.
