season extends from spring to late summer. Eggs are released in a thin film on the surface of the water. Spawning takes place in permanent bodies of water and the tadpoles overwinter one or
more years before reaching maturity. The Bullfrog has a deep resounding call that easily distinguishable from all other frogs. In Kentucky's chorus of frog calls, the Bullfrog
sings bass.
