LINCOLN, Neb. (AP) -- An animal expert at the University of Nebraska-Lincoln has released a CD of the rhythmic stylings of Nebraska's native frogs.
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. The CD is on sale at Nebraska Maps and More on campus.
Ferraro says listening to frog calls helps scientists track populations.
