Green Tree Frog

Green Tree Frog, Hyla cinerea


While doing plant survey work by boat on the Mattawoman and Chicamuxen tributaries, Dave and I observed a green tree frog.  The marsh where we found the frog is called Fine Grind Cove, which is dominated by arrow arum, and then to a much lesser extent, pickerelweed, sweetflag, narrow-leaved cattail and bulrush.


The green tree frog is a native southeastern species, with Maryland and Delaware representing the northernmost extent of its range, and extending south to Florida and west to central Texas.

In Maryland, it is considered a coastal plain species, primarily confined to the Chesapeake Bay counties.  The current Maryland Amphibian and Reptile Atlas (MARA) however, is showing that the green tree frog has some occurrences in the Piedmont, especially with hot spots in the Frederick area.


This frog may be found near water, such as a marsh, pond, lake, streams and rivers, and really likes fresh and brackish, tidal marsh wetlands, where we observed this specimen.  Note the large toe-pads, characteristic of tree frogs.  They can grow to 1.25 to 2.25-inches long and are primarily nocturnal insect eaters.


At my home in Howard County (the Piedmont), we have gray and cope’s tree frogs.  They are attracted to insects that are attracted to our kitchen lights.  At night, we sometimes see gray tree frogs stuck to our glass window, opportunistically feeding on insects.  Always a nice summertime evening scene to watch.  My wife says “how would I know,” as I rarely do dishes, overlooking the kitchen sink window.

Here is what the green tree frog sounds like:
