Did you have any guesses as to the identify of the animal making this strange sound? Would you be surprised if I told you it was from a kind of amphibian–specifically a Pickerel frog?
Pickerel frogs are found in the eastern United States, with the exception of the extreme southeast. They live near slow-moving water and in other damp areas, preferably with low, dense vegetation. They are 1 3/4 to 3 1/4 inches long. Their underside is light-colored with yellow where the legs meet the body. They have two ridges along the sides and back of their bodies–called dorsal lateral ridges.
Pickerel frogs producing an irritating skin secretion that makes them unappetizing to some predators. This secretion may kill other frogs if kept in the same container for any length of time.
