If you followed the sound down along the Lower Impoundment to the first break in the reeds you would have been greeted by a veritable frenzy of toads. It seems that the warm weather had turned their hearts to love. You would find toads calling, mating, and chasing other toads to either capture a mate or chase away a potential suitor.
At times the noise was quite loud. In this video the toads are closer than the airplane, but notice the relative noise levels.
It was impressive when you would see the male toads expand their vocal sac and start to call. It would expand to almost twice its normal size.
Of course along the way other toads try to horn in on the action. It seems that one of the defensive strategies is for the couple to submerge leaving the chasing of mates to the toads on the surface.
