Beavers have colonized the stream in previous years. Deer travel up and down the park year round. Hawks, crows and turkey vultures search the area for food.
I have watched a couple of crows looking for food on the ground while a turkey vulture watched them from a tree and a hawk circled overhead. On warm nights a symphony of frogs fills the air. Other animals fairly common around Pimmit Run include: squirrels, moles/voles, chipmunks, mice, opossums, raccoons, red foxes, great blue herons and green herons, black rat snakes and many kinds of birds.
Animals not abundant in the area, but which can be spotted, include the mallard duck and bald eagle. There are also rumors spread by people in the local nature center of a river otter making its way up stream. Although it hasn't been seen, tracks indicate its presence. Screech owls are very rare in these parts. I do know someone lucky enough to have seen them. He saw a young owl just learning how to fly. Its parent was in a nearby tree. Crows kept trying to kill the young owl, but the parent
kept divebombing the area. The observer went back to his house to get some work done and left his son to help keep the crows at bay. Later, when he found the owls had gone, he asked his son what had happened. His son said that the parent flew down next to the baby owl, which crawled onto its back, and the two flew away together.
The stream itself is inhabited by many types of minnows and larger fish. The stream also houses eels, eastern crayfish, and salamanders, as well as other invertebrates. I've also seen box turtles along the stream.
