Frogs

The following frogs have been heard at our wetland.

Bullfrog (Rana catesbeiana). The deep-pitched call of this large frog can be heard from April onwards. The tadpoles, which can be more than 6 inches long, take 2 years to become adult frogs. Tadpoles are often seen in the water.

Southeastern Chorus frog (Pseudacris feriarum) is a smooth-skinned frog, ¾”-1 ½” in length, ranging from greenish-gray to brown in color, with 3 characteristic black stripes down its back, although they may not be completely connected or solid. There is also a dark stripe through the eye and a white stripe along the upper lip. Its croak is a series of rapid clicks, much like the sound made from running a fingernail over the teeth of a comb. It last 1-2 seconds and rises in a rasping tone.. These chorus frogs can be heard at our wetlands in early spring (starting in February) and in the fall. Chorus frogs breed in winter (in warmer areas) or in late winter to early summer (in the cooler areas of the country) and lay up to 100 eggs, attaching them to vegetation. Once grown, the frogs live in grassy areas that can be swampy or dry. They are found in much of the country, ranging from Alberta to Northern New York, south to Georgia and west to Arizona (not including New England, the northern Appalachians or the Southern Coast).

Eastern Narrow-mouthed Toad (Gastrophryne carolinensis) is a triangular looking gray, brown or reddish-brown frog, 1”-1.25” in length with dark markings on the back. A fold of skin can be found just behind the eyes. These frogs are explosive breeders, especially during summer rains. The females lay up to 150 eggs on the surface of water during this time. Its voice resembles the bleat of a lamb, lasting .25-4 seconds. They are found all over the state of Tennessee, except in the Blue Ridge Mountains, under rocks and logs or underground. These frogs are heard during the summer in our wetlands.

Southern Leopard Frog (Rana sphenocephala) This frog is heard in spring (from mid-March) and is 2½ to 3 inches with a long, pointed snout. It is green and brown with dark round spots on its back. Leopard frogs are quite often seen in this wetland.
