Northern Leopard Frog (Rana pipiens)

Hear what this frog's call sounds like!

This frog is fairly large (about 3 inches) but is very secretive. Leopard frogs are bright green, with random black or dark brown spots on their backs, each surrounded by a thin light yellow border. Leopard frogs were extremely common as recently as 30 years ago, but their numbers have decreased more and more. They are usually found near trees.

The leopard frog's call is very quiet. It is also a two-parted song, consisting of a long (about 3 seconds) "snore" and alternate short grunts.
