Don’t assume that because you hear some quacking it’s ducks making the sound.
It’s the season for quacking frogs in much of the country. With the first warm, thawing rain of the spring, Wood Frogs emerge from their winter quarters—under logs or beneath leaf litter—and migrate to their favorite woodland ponds and bogs. When a frog reaches its destination, it starts calling for mates. That’s where the quacking part comes in: a chorus of male Wood Frogs sounds an awful lot like a flock of quacking ducks.
Wood Frogs breed from Alaska to Labrador and south to southern British Columbia, northern Illinois, and the southern Appalachians. Their quacking, depending on latitude, can occur between January and July. Keep your ears open.
Listen to a Wood Frog's song-- it really does sound a bit like a duck! »
There was no Wood Frogs song on the page that was supposed to link to it. : (
