Yesterday I visited a favorite pond in the Allegan Forest. For years I knew the pond as a seasonal marsh which went dry every summer, but over the past decade or so it has steadily filled up with water and no longer goes dry. It is host to an enormous number of dragonflies and also frogs, toads, turtles and more. Periodically, a huge number of these tiny toads flood the grassy savannah near the pond: 

This is an Eastern American Toad, Anaxyrus americanus. It was quite small, roughly comparable to a US one cent piece in size. Here is a very crude comparison shot:

The field was teeming with these little toads yesterday, something that happens now and then in late spring or early summer. There were literally thousands of these tiny creatures making their way through the fields and into the adjacent woods.
