Eastern narrowmouth toads, and a few grey tree frogs, were calling from a roadside gutter near my house after a big rain two days ago. Yesterday there were egg masses all over one end of a little pool in the gutter. I believe they are from the Narrowmouth toads. I'm going to try to rear a few--the embryos have already changed a lot.
Update 8/29/09
I had originally thought these were Narrowmouth toads, Gastrophryne carolinensis, but my one transforming tadpole on 8/29/09 is clearly a Gray Treefrog, Hyla chrysoscelis. (This individual, unfortunately, died right as it was transforming, but the species is clear.)
A tiny gray tree frog has been hanging around on my deck railing He's green because he's near the morning glory trellis and those bright green leaves, These guys are nocturnal so I think this is sleeping posture. He's only about an inch long.
A Gray Tree Frog rests at the edge of a smooth green blade, its eyes wide and alert in the soft light.
I photographed this little frog at Sequoyah National Wildlife Refuge in Oklahoma. It was perched calmly among the grass, unmoving but aware of its surroundings.
Though called a Gray Tree Frog, this species often appears green like this one. Their color-shifting ability helps them blend into leafy environments, making them well suited to the wetlands and woods they call home.

This is a young grey tree frog (hyla versicolor). These frogs can be all green, all grey or a mixture of both. The little ones I've seen are mostly green. The one adult we found was ALL grey. It looked like a rock.

As the scientific name implies, gray tree frogs are variable in color owing to their ability to camouflage themselves from gray to green, depending on the substrate where they are sitting. The degree of mottling varies.[3] They can change from nearly black to nearly white. They change color at a slower rate than a chameleon. Dead gray tree frogs and ones in unnatural surroundings are predominantly gray. The female does not croak and has a white throat; however, the male does croak and has a black/gray throat. The female is usually larger than the male.
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). Their skin has a lumpy texture to it, giving them a warty appearance. They are virtually indistinguishable from the Cope's gray tree frog, H. chrysoscelis, the only readily noticeable difference being their calls. Cope's gray tree frog has a shorter, faster call.[4] The gray tree frog also has an extra set of chromosomes (4N), or 48 in total, and is called tetraploid gray tree frog in scientific circles. The Cope's gray tree frog, or diploid gray tree frog, retained its 2N (24) original chromosome set. Hybridization between these species results in early mortality of many larvae, but some individuals survive to adulthood though they have reduced fertility.[5]
Both H. chrysoscelis and H. versicolor have bright-yellow patches on their hind legs, which distinguishes them from other tree frogs, such as H. avivoca.[6] The bright patches are normally only visible while the frog is jumping. Both species of gray tree frogs are slightly sexually dimorphic. Males have black or gray throats, while the throats of the females are lighter.[7]
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. At 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 and turn gray or darker green after reaching adulthood.
Went out at night and found this Gray Tree Frog on my driveway. Put him on a plant to get him out of harm's way...took a few shots. Returned 15 minutes later to find a rather drastic color shift. Less Driveway, More Plant.
I have never seen one so small before. I didn't have anything on me to stick in the shot for comparison. Rugosa Rose leaves was the best I could do ;) In all the years here, I have never been lucky enough to see them mate or find their eggs.
. . . and this is what happened to me. So I'll be absent for a few days while I metamorphose.
Incidentally, for you non-herpetologists out there, this is a gray tree frog (Hyla versicolor)
I was very excited this past Saturday 10 Aug. 2019 to find about a dozen tiny Gray tree frogs on plants and trees close to a frog pond I often visit for dragonfly and frog photos.
I first noticed these amazing little frogs at this location in 2014. I saw them again in late summer 2015, but then poof gone for 2016, 17 and 18. I feared that they had totaly died out. Then Saturday after looking around the trees and plants near the pond I found none and was on my way back to my car when I spotted the first one on a low leaffy plant on the tree line, then I saw another and another all hiding in plain sight.
They have the ability to slowly change their color to the color of whatever they are sitting on which is a very effective camouflage.
I'm finding little tree frogs and peepers everywhere. Snuggled in the leaves they can easily be overlooked. It's interesting they turn away from me each time I try to get a picture of their faces. Might be they are a bit worried that a giant has picked them up and moved them this way and that? Hope they are none the worse for their ordeal....it certainly makes my day when I find one :) Young Gray Treefrog (Hyla versicolor or Hyla chrysoscelis).
My neighbor had Gray Treefrogs breeding in his pool cover this spring, and he saved a handful of tadpoles for me when he opened up the pool. - Allegany County, NY, USA

This is a young grey tree frog (Hyla versicolor) we found sitting quietly in the grass. When we tried to catch her, she leaped onto my Yakima cargo box, which was down on the ground being washed. The dimpled black surface made for a nice setting for her to pose!
The younger grey tree frogs are bright green. They eventually turn to a very light mottled grey color with the appearance of maple bark or even a light piece of granite. This one still has a very faint hint of green on her skin.

The wetland area was filled with these tiny Gray Tree Frog youngsters. This one still had quite a tail.
The tree frog soon decided that Don's shirt looked more like a tree than Don's hand did, & decided to go climbing. This shows the bright, bright yellow on the legs -- completely hidden when the frog is sitting still. I also kinda like the dynamic feel, the way you can see the biomechanics -- applying leverage from the rear toes.
Cope's Gray Treefrog - Hyla chrysoscelis (Dryophytes chrysoscelis)
This individual was lollygagging around in a little roadside puddle mid-morning in Durham NC. I have video/audio of them calling in the puddle from a few days prior. I believe that rapid trill verifies the ID as Hyla chrysoscelis. (Eastern Narrow-mouthed Toads were also calling.)

Note, also, that chrysoscelis seems to be the only species found in the lower Piedmont of North Carolina, as opposed to the nearly identical H. versicolor.
I used a circular polarizing filter to suppress glare off the water's surface.
A few glamor shots of a little Gray Treefrog I saw earlier this month. I love finding these guys and getting a few photos but their camouflage is just so good. I am sure I am missing many more than I am seeing.

I don’t know if this is an Eastern gray tree frog or a Cope’s gray tree frog. It was less than an inch long and sitting on the arm of my patio bench. I tried unsuccessfully to get a better shot of it, but it and the sun wouldn’t cooperate.
