Lithobates catesbeianus (Rana catesbeiana). The American Bullfrog is our largest native frog. You can hear the males calling “roo-roo-room,” or “jug-o-rum" in the spring. The diameter of the round, flat eardrum behind the eye is larger than the eye itself in males, and equal or smaller in females. Image by Stephen Barten
Lithobates (Rana) pipiens. The Northern Leopard Frog has dark, leopard-like spots. This is more of a grassland species than pond species, except during the breeding season. Image by Stephen Barten
Pseudacris maculata (P. triseriata). These inch-long frogs with three dark brown stripes are the most common frogs in the Barrington area. They can be heard calling from every pond and roadside ditch in the spring. Image by Stephen Barten
