Keel-billed toucans are a species of toucan that live in Central and South American rainforests. It lives in hollow trees, and eats fruits and insects. They live in groups of usually 10 to 12, and exhibit many social and playful behaviors. They have many adaptations, including developing wings to fly, flexible feet to grip branches, and beaks to find food, attract mates, and fight off predators. In the future, rainforests that the keel-billed toucans inhabit become dry savanna. The toucans will live in trees, but in smaller groups to save space and make them inconspicuous to predators. They will develop teeth, and eat more insects than fruit because insects are more abundant in the savanna. They will become less colorful, and be named the brown-billed toucans. They will also develop a hump to store water, similarly to a camel. Their wings will become lighter to help them fly more easily.
