Mammals, Amphibians, and Reptiles
Acadia contains a variety of natural habitats that provide homes for many different animal species. Our location on the coast and the diversity of habitats explains this species richness. The size of these habitats and their separation from other habitats or larger natural habitats, however, limits the types of animals that are found here. Small animals adapted to smaller habitats are therefore more common, unlike the large mammals such as black bears and moose that require large areas and are rarely observed.
With a record of 338 bird species encountered, Acadia National Park is considered one of the premier bird-watching areas in the country. Twenty-three species of warblers alone have been recorded as breeding in the park! Click here for a checklist of the birds in the area.
