” In this area there are many types of mammals. The mounds of dirt that you see are made from the huge front claws of the Townsend’s mole. As the moles make underground tunnels, they push the dirt to the surface. Moles eat worms and insects and store this food in their tunnels.
Look at the tall grass behind you. If you are quiet enough you might see black-tailed deer, which feed on the grass and small plants. When the deer lay down to sleep it flattens the grass.
Brush rabbits and raccoons live on Oak Island, too. Bats are night animals, coming out right before dark to feed on insects. From this point you might see river otters because they like areas around water.”
