calls

Mandookavani (Sanskrit: Mandooka - Frog, Vani - Speech) is an acoustic guide to the frogs and toads of the Western Ghats. Frogs and toads (together called anurans) have evolved to communicate vocally. Anurans produced sound by vibrating vocal chords as air is pushed over them through lungs. The sound thus produced gets amplified in a balloon like vocal sac. Each species has a unique calling pattern and hence can be used as an identification key in the field.
