It’s dark, and stars are dimly shining above the mountains. You’re outside with a warm summer breeze tickling the leaves. What do you hear?

If there is a pond or wetland a kilometre away—and in the Fraser Valley there often is—you might hear the low foghorn call of a bullfrog. If the pond is closer, you might hear the sound of a plucked rubber band coming from an adult green frog, or the cricket-like ribbit of a Northern Pacific treefrog. If you’re particularly lucky, you may hear the stuttering call of the red-legged frog or even the rapid staccato of the Oregon spotted frog.
