To It 10-mile Circuit Hike Accotink Cr. The Stream History Cross-County Trail General by Mark Niedringhaus 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. 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.
