[…]These chorus frogs are quite common over the Eastern U.S. and Southeast Canada.  They are typically 1″ to  1 1/2″ long.  Only males “sing” and use this call to attract a female.  As temperatures fluctuate in the spring, the chorus frog can survive the freezing of its body fluids down to 17 deg. F.  They eat ants, beetles, flies, spiders and other insects.  A female can lay 900 eggs.  A typical spring peeper will live about 3 years. Listen for them now if it’s quiet and you have a pond nearby.
