Green Frog
Green Frog
Rana clamitans melanota
Tioga County, NY

Identification- 2.5-3" Variable amount of green and brown.  Typically green on nose and back fading to brown posteriorly.  Well developed dorsolateral folds.  Dark spotting on head and back.  Legs crossbanded.  Pale venter sometimes with dark mottling.  Males have yellow throat.
    Voice- a sudden explosive twang low in pitch.  Likened to a plucked banjo string.  Makes a high pitched squeak when startled.
    Similar Species- Mink Frog of northern New York is similar, but typically has mottled back and hind legs and a musky odor.  Green Frog's crossbanding on legs will separate the two. Bullfrog lacks dorsolateral ridges.

Range- Found throughout the state.

Habitat- Almost any permanent or temporary body of water houses at least one Green Frog.  Streams, rivers, ponds, lakes, and ditches are just some of the habitats in which Green Frogs can be found.

Reproduction- Males can be differentiated from females by yellow throat, eardrum larger than eye, and swollen base on the thumb.  Females have pale or mottled throat and eardrum same size or smaller than eye, and no swelling on base of thumb.  Breed throughout the early spring to mid summer.  The large mass of eggs is attached to submergent vegetation and can be up to 12" in diameter.  Tadpoles can be quite large growing three to four inches in total length and are green-olive above with dark spots and a coppery venter.

General Characteristics-
    One of the most common frogs in our area.  Green Frogs are found throughout the state and can be found in most freshwater areas.  Although they are conspicuous by voice, like all frogs they can be difficult to approach and are quite wary.  They emit a high pitched scream when disturbed that alerts other frogs to a predator's prescence.  Mostly nocturnal, Green Frogs hunt a large variety of vertebrate and invertebrate prey.  Being one of the most common frogs in the state they are preyed upon by a large number of aquatic and terrestrial predators such as Large fish, herons, raccoons, mink.
