The Green Treefrog, Hyla cinerea, must be one of the most common amphibians in the south. Fortunately it is a lovely thing. Seems to accept any habitat that has enough water to wet its toes in. And there is that lovely quacking call. In the most crowded frog calling areas, where the hormones are truly pent up, the noise can be astounding. These guys are camouflaged to near perfection for all the greenery that surrounds their water habitats. One can walk up to a fine area and stand and pick out frogs like a game of find-the-hidden-picture.

Suction cup toes, inimitable smile -- what is not to like?? In Arkansas, it would be difficult to mistake these for anything else.

In Bell in September, things must be winding down for these guys but this one was out in the daytime actively hunting insects. This is a winning face, no matter who you are.

In Florida, it is not as clear cut. This is the green form of the Squirrel Treefrog, Hyla squirella. They seemed to be highly attracted to the port-a-potties there. Possibly because they were lit well and attracted insects.

The Gray Treefrogs, Hyla versicolor (Gray Treefrog) and Hyla chrysoscelis (Cope's Gray Treefrog), come in two classy versions that are visually identical. The difference is in the speed of the male singing voice. And astoundingly, one species has 48 chromosomes and the other 24. The voice unfortunately varies in both species with temperature. Though with the recordings from Lang Elliott I believe the voices are separable at any given temperature. Cope's having a rougher waaaaa sound with less warble and overall less musical than the Gray. I believe that most of the treefrogs calling at my property are Cope's. Trauth could hear both species in one spot in Mayflower AR, which is just a few miles from my home. Also according to Trauth's new Reptiles and Amphibians of Arkansas the chromosome number is not the factor involved in the voice change. (What??) Trauth's map for the chrysoscelis (Cope's) tends to be in the southeastern portion of the state, if that helps. But the above frog is from Baxter county and is likely versicolor.

These are ventriloquist frogs which sound like a woodpecker crossed with a door hinge. They like forested areas throughout much of the state. Often come to windows with lights and manmade dwellings looking for the bug concentrations. This one is pictured on a window frame.

The face of the Cope's/Gray, with those amazing eyes, on my front porch where they still hunt under the lights and call from my wife's potted plants. Occasionally the one on the porch will talk to the ones out in the Canna plants conversationally, especially on cloudy summer days after rains. The Canna more often harbor Green Treefrogs however. This is very likely a Cope's since this is the much more common vocalist on my land.

The full upper surface and note how they do adjust their overall tone to the tone of the brick and vanish. Except for that bright orange between the toes.

This Gray/Cope's took up residence on my back window ledge in spring of 2015. Hid behind a plant tray most of the day. Came out in the lights at night. Most of the calling frogs were Cope's for this month of April. I don't get tired of these.
Hiding in my wife's strawberry pot, also in spring of 2015. A smaller version, also likely a Cope's. 

The remarkably different Hyla from south Arkansas from Keith. He likely is in the land of Cope's Grays but Trauth shows both species verified in the south counties as well. I have never seen one with this coloration in my central AR woods. A recording he made there seems to suggest he has almost pure Cope's.

Gray face, same individual. Very nice whichever Gray it is.

The holy grail of treefrogs in Arkansas. This is the Bird-voiced Treefrog, Hyla avivoca. It is known from about ten counties now. Can be heard in the areas where it is known from in spring but is rarely seen. Always found near wooded swamps and flooded tupelo and cypress areas. This is one from the Bell Slough population which sings in April. They were first discovered in their disjunct population in Arkansas in about 1977 after someone dredged up some recordings from 1959 that proved they were in the state. Subsequently they were found in Conway county and Saline county. I got to hear them in Conway county in 1977.

This is the male (same individual). The female is twice this size and kind of tree-bark gray with a gray treefrog camo pattern. This male was about two feet off the ground on this buckeye leaf. Though they always sound like they are thirty feet up, apparently males usually call from 1 to 2 meters off the ground near the swamps. It was a good thirty yards to the swamp where this one was located. The voice is haunting and birdlike, like a musical Pileated Woodpecker call. It is amazingly ventriloquistic. This one was not calling when I stumbled upon him. But there were many around him that were.

The superb shot of a male in mid-call from Keith Newton in south Arkansas.

This is very likely an eye shot of a female. I have never found a female. This is also from the southern woods near Keith. Females are twice as large as males and tend to be browner and greyer. I await my first.

And a perched female in the Bird-voiced and Cope's woodland of Keith again. 

And, well, both sexes, making more Bird-voiced creatures for the world to enjoy. 

David said this individual still had its tail and may be a fresh male. We initially thought it was a Bird-voice but Henry Robison feels this is a juvenile Green Treefrog. So beware the youngsters in an area not proven to have Bird-voiced colonies. This was taken near Red Slough.

This Gray (or Cope's Gray) was only abut 3/4 of an inch long in April 2011. In my yard again. You can see that this one may be just transitioning to the purely gray coloration. I think the Grays have quite a bit of green on their backs in the very smallest stages. It is possible the Gray and Cope's Gray have different early color pattern changes. I am not sure at this point.

This is another juvie Gray (or Cope's Gray) from the Canna in the front yard. They seem to find their way there to grow up in size. This is a July frog so it must be from the great choruses of spring 2011. A big hatch here by sonic measures. The green of the back retracts weekly and the face and legs gray up.
