Juvenile Gray Treefrogs Appearing

8-16-17 immature gray treefrog 049A2580

Being my favorite species of frog, the Gray Treefrog may get more than its fair share of exposure on the Naturally Curious blog.  This amphibian is rarely noticed outside of its June mating season, when the males’ bird-like trills can be heard throughout the night from shrubbery bordering wetlands.  Due to its emerald green coloration when young, and its mottled gray/green adult appearance, in addition to its nocturnal habits, this beguiling amphibian escapes detection by most of us throughout the rest of the summer.

However, if you keep an eye out in August,  near where you heard those trills in June, you may be successful in spotting a juvenile Gray Treefrog.  Having developed legs and lungs, absorbed their gills and tails, and reinvented their digestive system for insects, not plants, they are now permanently terrestrial, except during the breeding season. When a Gray Treefrog is young and newly metamorphosed, it usually remains near the forest floor. As it ages, it may transition to living in the forest canopy.

    Agreed, Mary…these are awesome frogs. I took some videos of an adult, breathing, & some really good photos. They have an interesting, “sticky” texture, if you touch them. Their coloring is incredible. So cool that they can just “adhere” to a vertical surface.

    I sent this post to my daughter, ( Rockland, MA)…she said they saw an adult this evening and a juvenile a few evenings ago on a door. I’ve seen 3 adults, in the past years.

    So, where do I look for them? Near the ground by the water, or in the tree? How far up in a tree?

    • Usually, unless they are mating, I’ve found them calling within 10 feet of the ground, in shrubs, well hidden.

    I once had handheld electric grass clippers and when I ran them the tree frogs in the maple trees would answer. No doubt they envisioned some very attractive potential mate!

    I have one showing up on my deck railing under a plastic tray that a plant sits on. It stays there all day and then is gone for a few days. But he keeps coming back once or twice a week. This is the first summer I have seen any at all.
