A: Toucans are preyed upon by jaguars, margays, owls and boas. Despite its large bill, a toucan has little in the way of defending itself against predators.

Toucans use their loud, shrill voices to scare away predators and may sometimes beat a tree branch with their bills to warn their enemies away. A toucan cannot use its bill to fight off a predator. It's bill is hollow and made of keratin, and therefore, not strong enough to withstand a fight.
