Toucans mainly eat fruit. But they are what’s called “opportunistically omnivorous” which means that they eat animals like lizards, birds, and insects that are available in order to survive. Basically, imagine that you’re a vegan, but suddenly you’re flung to a faraway carnivore planet with no fruit, vegetables, plants, or nuts, and the only sources of food are animals. You’re told that you’ll be rescued in a month’s time. You’d eat what you’d have to eat to survive until then, wouldn’t you?
