One of the first amphibians to appear in the spring is the wood frog – and they were out in force last night, migrating from the woodlands where they live and hibernate to the ponds where they breed. Thanks to their paired vocal sacs, which act as resonating chambers for their duck-like calls, they can be heard far and wide. You can both hear wood frogs and see their sacs inflating by going to http://www.youtube.com/watch?v=-qc_r2sfQUc .

Naturally Curious with Mary Holland
Dear Mary,
The wood frogs started “quacking” at the small pond in our Sunapee, NH yard yesterday. The ice had just barely melted and there’s still a bit of snow left on the ground. It’s nice to see another sign of spring.
