Lithobates pipiens

Less common than the pickerel frog, which it resembles in both appearance and somewhat in call, the leopard frog typically breeds in shallow marshes, weedy ponds and open vernal pools. Listen for their staccato version of the pickerel frog growl, mixed with chuckling grunts in early to mid-spring.
