Toco Toucan

Ramphastos toco

The largest toucan, with a huge orange bill that is light because it is made of keratin.

About the Toco Toucan

Toco toucans are the largest toucans: about 25 inches long, including a 7.5-inch bill, and almost 2 pounds. They have the largest bill compared to body size of any bird. The bill is made of keratin, like your fingernails, so it is light. They live in woodlands near rivers, savannas and shrublands of South America and eat mostly fruit, plus insects, eggs and chicks.[1]
