Recently, I was at the Cape May Zoo in New Jersey and was able to take this image of a Gray Tree Frog (Hyla versicolor). One of my favorites, this tree frog is often heard, but seldom seen. It has a familiar call and is one of the last amphibians to breed in New York state. You can often hear males calling right through July. From time to time, people will bring one to the Zoo for me to identify. The are not rare here, but people are surprised to come across a “treefrog”. Gray tree frogs can survive long New York winters by using a glycerol produced in response to freezing of their extremities.
