Frogs may have had the first voices on the planet, and this 1957 recording shows off their amazing variety of croaks, chirps, barks and honks. This reissue, narrated by the former Curator of Amphibians and Reptiles at New York"s American Museum of Natural History, features 54 minutes and 57 species of frogs and toads, recorded in their natural habitats. Fascinating-slimy, but fascinating.
