Pickerel Frogs emerge early in the spring from their muddy, pond bottom hibernacula, and mate in April and May in the Northeast. As part of the mating ritual, males call to attract females, with the calls resonating inside their internal vocal sacs located between their tympanum (ear drum) and foreleg (unlike Spring Peepers and American Toads, whose vocal sacs are located directly under their mouths).
These low-pitched calls resemble short “snores.” Occasionally Pickerel Frogs call from under water, but even when they are above water, their calls do not carry very far, frequently making it difficult for human ears to hear them. Their call is similar to that of the Leopard Frog’s but lacks the short grunts of a full Leopard Frog call. You can compare these two calls (and several others) by going to http://langelliott.com/calls-of-frogs-and-toads-of-the-northeast/ (Sound recording © Lang Elliott – langelliott.com)
Next to the Green Frog, the Pickerel Frog is the most abundant frog in New England. It is often confused with the Northern Leopard Frog, which it closely resembles. The spots on a Pickerel Frog’s back are squarish and aligned in rows, whereas the Leopard Frog’s spots are rounded, and randomly scattered over its back. In addition, the male Pickerel Frog has bright orange on the inner surface of its hind legs, which the Leopard Frog lacks.
Recently male Pickerel Frogs have started calling to attract mates. Each species of frog, just like each species of bird, has its own distinctive call. Spring Peepers “peep, “ Wood Frogs “quack” and Pickerel Frogs “snore.” Their snore isn’t long – it only lasts a second or two — but it is unmistakable. Pickerel Frogs call from under water, as well as on top of mounds of vegetation, so if you hear one, and then search for it, you may not find it.

Starting with today’s post, my blog will occasionally be enhanced with the sound recordings of Lang Elliott. For those of you who may not be familiar with his work, Lang Elliott has made world-renowned recordings (that are commercially available) of the vocalizations of birds, mammals, insects, frogs and toads. If you’ve ever wondered what out-of-sight creature was singing, screaming, trilling or buzzing, his CDs and books will give you the answer.

If you’ve spent time at a pond recently and heard what sounded like someone snoring, you weren’t hallucinating! Male pickerel frogs have started calling to attract mates, and each species of frog, just like birds, has its own distinctive call. Spring peepers peep, wood frogs clack and pickerel frogs snore. Their snore isn’t long – it only lasts a second or two — but it’s unmistakable. Pickerel frogs call from under water, as well as on top of mounds of vegetation, so if you hear one and then search for it, it’s very possible you may not find it.
