Don't expect any top 40 hits

Don't expect it to be a major smash hit, but there's a new CD featuring the rhythmic stylings of Nebraska's native frogs.

University of Nebraska-Lincoln herpetologist Dennis Ferraro says frog songs are all about attracting a mate.

Male frogs produce a simple bass line to say they're in their own territory and a higher-pitched melody to coax females to come over.

Female frogs don't make the sounds.

Ferraro's CD, "Frog Calls of Nebraska," features 11 tracks, each about one and half to 2 minutes long.

It's not just entertainment. Ferraro says listening to frog calls helps scientists track populations.
