Wood Frogs Arrive at Vernal Pools

After noticing the sudden loud clacking chorus at a nearby temporary woodland vernal pool, I went down to investigate, and there were dozens of wood frogs floating on the surface, as they croaked their duck-like quacks in the hopes of attracting female wood frogs.  As far as I could determine, they were out of luck on this, their first day at the breeding pool, as I don’t believe the females have arrived yet.  One clue was the relatively small size of the floating frogs and it seemed as though every frog was calling (only males call).  Plus, time after time a wood frog would swim up to another wood frog and attempt to grasp it only to have the object of its desire utter a “release” chirp (a call made only when a male clasps another male) and swim rapidly away.
