An Eastern Gray Tree Frog (Hyla versicolor) on the window in macro from the outside looking in. It's hard to tell the difference between this and the Cope's Gray Tree Frog since I didn't hear it. That's basically the only way to tell them apart. The next photo is from the inside looking out. You can seen the bottom of the frog. You can also see the slime on his feet to help him stick to stuff. #TreeFrog #EasternGrayTreeFrog #animal #grenouille #Frosch #Tier #ribbit #Rippchen #côtelette
Not sure what this is, thinking a grey tree frog, though its markings aren't as distinct as what I'm seeing online. Feel free to offer a correction.
It's a tiny thing with striking golden brown color, but of course gray treefrogs can be brown, or green, or whatever apparently. I tried encouraging it to pose but it was pretty uncooperative for a frog.
This young tree frog was only about an inch in size! The frog was resting on a Black Eyed Susan leaf !
A cute little Gray Tree Frog that I photographed just outside Blackwater Wildlife Refuge in Maryland.
Taking a break from the spring wildflower posts today. We were out in the woods hunting for wildflowers when my wife spotted this tiny tree frog trying to warm up in the sun. (I walked right past her even though I was looking down at the ground.) She is about 1.5-2 inches (4-5 cm) long and the coloring camouflages her nicely. I'm sure this is the same species I've seen later in the year sitting on a green leaf and they take on the green color then. (Hence the scientific name Dryophytes versicolor) I am referring to her as a female because she appears to have a white throat that males do not have.
Because this brand new gray tree frog still had part of its "tadpole tail" on, I'd like to think this particular morning was its first day on land. There were two others nearby, probably siblings, in the exact same stage of development. Photographed in the Stry Nature Preserve near La Crosse, Wisconsin.
Found this little Gray Tree Frog between the glass table top and iron base, in the shade of a potted plant on the table. He seems content.
I found this fellow the other day jump out from my tomatoes as I watered them (I have to grow them in pots because of Shadow). I needed to get my macro lens out to photograph him--couldn't have been much more than half an inch long. I think the ID is correct--if not, feel free to correct me. (Got its ID from Google Lens.) He's sitting on a Hydrangea stem.
Thanks for Viewing.
We have two gray treefrog species (Cope’s Gray Treefrog and Gray Treefrog) which are identical in appearance and can only be distinguished by their call. Since this juvenile gray treefrog chose to remain silent, we will just have to settle on “gray treefrog” for identification. This little guy was less than an inch in length and is resting on a leaf.

For the first time today we explored hiking trails around a tract of forest and meadow formerly known as Schaefer's Woods. They are now part of the Avon Trail between Conestogo and St. Mary's, providing a link between the Grand River and Thames River. This tract is not far from where we live, and I look forward to visiting it more often.
Danny's sighting of this gray treefrog on a milkweed plant can be taken as a good omen.
Thank you to everyone who visits, faves, and comments.

This treefrog was found sleeping up in a tree. Gray Treefrogs can change from the colors of gray to green, depending on substrate where they are sitting.
The grey treefrog is a species native to much of the eastern United States and southeastern Canada. This one does not look as impressed at seeing me, as I was at seeing it.

Snakes are the big draw on Snake Road, but frogs were present in large numbers. This little guy stood still for a nice pose. LaRue-Pine Hills, Illinois
Excerpt from Wikipedia:
The gray treefrog (Dryophytes versicolor) is a species of small arboreal holarctic tree frog native to much of the eastern United States and southeastern Canada.
It is sometimes referred to as the eastern gray treefrog, northern gray treefrog, common gray treefrog, or tetraploid gray treefrog to distinguish it from its more southern, genetically disparate relative, Cope's gray treefrog.
As the scientific name implies, gray treefrogs are variable in color. This ability to vary their color provides them with the ability to camouflage themselves from gray to green or brown, depending on the environment around them. H. versicolor can change from nearly black to nearly white. They change color at a slower rate than a chameleon. A unique aspect of the appearance of gray treefrogs is that its legs feature a dark band-like pattern which then contrast sharply with the black-marked bright yellow or orange under the sides of its legs and arms. Dead gray treefrogs and ones in unnatural surroundings are predominantly gray. The female does not call however, the male does call. Female gray treefrogs are usually larger than their male counterparts. They are relatively small compared to other North American frog species, typically attaining no more than 1.5 to 2 in (3.8 to 5.1 cm) in length. Their skin has a lumpy texture to it, giving them a warty appearance.
This species is virtually indistinguishable from Cope's gray treefrog, the only readily noticeable difference being that Cope's Gray treefrog has a shorter, faster call. This varies depending on the temperature, however, as the call rates of both gray treefrogs are temperature dependent. At lower temperatures, Cope's gray treefrog can have a call rate approximating that of the gray treefrog. This difference in calling can be heard, but it is best quantified by counting the number of pulses per second in their whistled trills. At usual temperatures, the gray treefrog has a pulse rate of 16 to 34 pulses per second, while Cope's gray treefrog has a pulse rate of 34 to 60 pulses per second. Even though there is potential for overlap, because of the temperature dependence of the pulse frequency the two species are easily distinguished where they occur together. At a given temperature, the pulse frequency for the gray treefrog is approximately 1/2 that of Cope's gray treefrog.
The gray treefrog also has 48 chromosomes (4n), and is sometimes referred to as the tetraploid gray treefrog in scientific literature. Cope's gray treefrog, or diploid gray treefrog, retained its 2n (24) original chromosome count. Hybridization between these species results in early mortality of many larvae, but some individuals survive to adulthood, but these individuals suffer from reduced fertility.
Both of these similar species have bright-yellow patches on their hind legs, which distinguishes them from other treefrogs, such as the bird-voiced tree frog. The bright patches are normally only visible while the frog is jumping. Both species of gray treefrogs are slightly sexually dimorphic. Males have black or gray throats, while the throats of the females are lighter.
Tadpoles have rounded bodies (as opposed to the more elongated bodies of stream species) with high, wide tails that can be colored red if predators are in the system. Metamorphosis can occur as quickly as two months with optimal conditions. During metamorphosis, the new froglets will almost always turn green for a day or two before changing to the more common gray. Young frogs will also sometimes maintain a light green color, only turning gray or darker green once adulthood is reached.

The Gray Treefrog is a native of Massachusetts, and apparently easier to hear than to see. One reason they are not easy to see is revealed in its scientific name: "Dryophytes versicolor." Like Chameleons, they can change colors from gray, to brown to green in order to blend with their background. I didn't realize such a frog might be native here. Had it not moved near my feet in our front lawn, I probably would not have noticed it. I gently placed him on this rock where it posed cooperatively for me before I placed him in a safer location nearby.

I did not realize how popular Treefrogs might be, so I thought I would post one more. ; )
It was 31 C (88 F) in the shade of the backyard yesterday, and this gray treefrog (Hyla versicolor) was quite content to sit and chill under the umbrella and table all day. We did not talk politics, but I'm pretty sure this one is a Green Party supporter. Shot with a Sigma 180 f2.8 macro with a 1.4x TC
This is either Gray treefrog (Hyla versicolor) or Cope's gray treefrog (Hyla chrysoscelis) - hard to tell them apart except for their calls. Hubby in the background. Here's a young one below. The babies are Cope's.
Best not to touch any of these bumpy frogs. Prior seasons at the wetlands, North Georgia - we've heard thousands of frogs this season but no treefrogs yet.
Found this little Tree Frog hanging out in our Hydrangea bushes. As I was taking pictures of him he took a leap right on my glasses completely took me by surprise.
Fifth and last image in this frog/toad series...
A profile view of this pretty frog as it rests on a tree branch. It was a thrill to discover and then photograph this amphibian!
This little guy hung out all summer in our backyard garden. He took residence in the Shasta Daisies. We called him Mr. Greenjeans. Everyday we'd go out and look for him and everyday he would be on one of the daisies. I suspect looking for a good meal. After we got adequately acquainted he let me photograph him with a hint of flash. I think this is his 'tough guy' look.
