Fun Facts
Spring Peepers are one of the loudest animals in CT! Their song is 90 decibels (about the same as a lawn mower). In comparison, the sound of Cicadas is 120 decibels.
Spring Peepers have a characteristic “X” pattern on their backs.
To make their calls, peepers squeeze air from their lungs, which causes the vocal sac in the throat to inflate like a balloon. The peeping sound happens as air leaves the lungs, passes over the vocal cords and into the vocal sac.
