Chestnut-mandibled Toucan, Ramphastos swainsonii


Chestnut-mandibled Toucan
This spectacularly large-billed and multi-colored bird is common and readily seen on the grounds of Bosque del Cabo resort at the tip of the Osa Peninsula in the far southwest of Costa Rica. The species in the genus Ramphastos are considered the "true toucans," with characteristic huge and bright-colored bills, as distinguished from their merely "large-billed" cousins the toucanets and arašaris. The bills are hollow, and so much less heavy than they look.


Chestnut-mandibled Toucan
Some authorities, including the American Ornithological Union, have recently come to
treat the Chestnut-mandibled Toucan as a subspecies of the Black-mandibled Toucan of
South America, in which case its scientific name would be Ramphastos ambiguus swainsonii.
