There is nothing that heralds the arrival of Spring like the sound of the spring peepers. I enjoyed listening to their chorus when it was warm enough a couple weeks ago to open the windows and hear them singing in the evening from the creek in the backyard. But frogs are often hard to see - especially now that the weather has turned cold again!
To get a wonderful close up peek at spring peepers and other frogs, take a look at Nic Bishop's book Frogs . It's filled with beautiful color photographs of a variety of frogs and fascinating facts about them, too. (Did you know that frog skin comes in every color and can even be see-through?) If you prefer butterflies or lizards to frogs, Nic Bishop has gorgeous books about those creatures, too, all recommended for children in grades 2-6.
Until the weather warms up again and the spring peepers resume their song, you can listen to them at this website from Naturesound Studio:
