NOTE: The toco toucan (Ramphastos toco), also known as the common toucan or giant toucan, is the largest and probably the best known species in the toucan family. It is found in semi-open habitats throughout a large part of central and eastern South America. Research has shown that one function of the bird’s large bill is as a surface area for heat exchange. The bill has the ability to modify blood flow and therefore regulate heat distribution in the body.
