These are frogs that live in and around my pond... some are in the trees, some hiding under leaves! During the spring they chirp these amazing sounds, sometimes morning, noon and night... it will go on and on as the winter receeds and spring warmth really takes over. By the time spring is fully warm they will go silent again.
You won't see a single frog in this video (cause they hide), but ya' can hear them all! Just close your eyes and listen....
