Various Artists Sounds Of North American Frogs
The amphibian song revival begins here! This classic of both biological fieldwork and natural sound recordings, compiled and narrated by renowned herpetologist Charles M. Bogert, was originally released by Folkways in 1958, and presents sounds of 57 species of frogs and toads (remastered from the original tapes) that were recorded in swamps, lakes, woods, creeks, and roadside ditches all over North America. Listen to the bewitching tones of the Pig Frog, Dwarf Mexican Treefrog, Little Green Toad, Southwestern Woodhouse's Toad, Great Basin Spadefoot, and other unsung heroes of the bog creek. In a time when frog and toad populations are in rapid decline, this recording reminds us of the remarkable diversity and beautiful sounds we are in danger of losing.
