Aracaris are toucans, in the genus Pteroglossus (along with the Saffron toucanet). Though the toucans are among the largest tropical birds, aracaris are relatively small members of their family. Aside from size, their omnivorous diet chiefly consisting of fruits, proportionally huge bill used for plundering fruits and nests of other birds, and their altricial (helpless at birth) chicks, are all characteristic of other toucans.
