Northern Leopard Frog: Hidden in the Grass

Over Memorial Day, my family and I explored Frotenac Provincial Park in southeastern Ontario, Canada. We called this park Frog Heaven because it was full of swamps, marshes, and  frogs ponds.

I saw a few bullfrogs, but my son spotted what I’m pretty sure is a Northern Leopard Frog (any herpetologists out there who would like to confirm this for me?) Below are a few photos: the leopard frog perfectly camouflaged and the same frog close up. The frog did not jump away when it sensed us nearby, but sat frozen in place—the better to hide from a predator. But that gave us the opportunity to take lots of pictures of it.

Leopard frogs, sometimes called meadow frogs, are found from southern Canada to northern Mexico. They are usually green or brown with dark spots. Northern Leopard frogs live in permanent ponds, swamps, marshes, and slow-moving streams throughout forest. Because they are especially sensitive to chemical pollutants, their numbers have declined since the 1970s due to acid rain and deforestation. You can read more about them and hear their distinctive snore-like call on eNature.

Please keep your eye out for frogs or other amphibians in your travels this summer. You might want to take pictures of them and submit them to the second annual Frogs Are Green photo contest (details to come later this week)!
