Got a frog in your throat?

The latest CD release in Nebraska might have some green with envy.
University of Nebraska herpetologist Dennis Ferraro has put out a CD called “Frog Calls.” It features 11 tracks of sounds from frogs native to Nebraska. Ferraro says some people who are interested in nature enjoy listening to frog calls when they’re relaxing.
Apparently the calls have rhythm, melody, and meaning. And he says the lyrics are like much of what humans sing about, finding a mate.
