The brown tree snake is an invasive species in the island of Guam. The brown tree snake feeds mainly on birds and other animals' eggs (birds and reptiles). The rapid increase of brown tree snakes has caused the extinction of several bird species. These birds mainly fed on insects. The brown tree snake does not have a natural predator.
