496 BEING GREEN - CHORUS FROG
A boreal chorus frog sings for a mate on the edge of a prairie wetland. Contrary to their name, they are a grassland species. About the size of a 50 cent piece, their call can be heard up to a mile away. Amphibians like this one are threatened by changes in water chemistry from additional inflows of water discharge and fragmentation of habitat from development. Powder River Basin, Wyoming.
