A rather fabulous male Bullfrog, Rana catesbeiana, that I encountered crossing the road. The mottling on the Bull is very variable. This one seems dark. Bulls never have ridges down the back on either side. And frankly none of our other Ranas get this big. Males can be told by that large eardrum. Female drum is equal to the eye size.

The lovely golden eye in close-up.

One of fifty thousand Green Frog, Rana clamitans melanota, hatchlings from the Nursery Pond near Lake Conway which is a Green Frog haven. These guys hang out near the water but when escaping are torn by their amphibious duality as to which way to run when frightened -- toward the water or away. Herds of them exited into the grass when I walked there on this day. Adult Green Frogs look like Bullfrogs in miniature and have two raised ridges down their backs that the Bulls lack.

And another color variation of the Bull. These are similar to the Green Frog but Bull's lack the dorsal folds as you see in the Wood Frog below.


And literally my best and only shot of the Bronze Frogs in my swamp. Rana clamitans clamitans. May even be a hybrid. Certainly a male. I was wading in the swamp listening to these and several other frogs talking. I was directing my attention to a Tiger beetle when up popped this guy right next to me. He stayed so long I waited for the overhead sun to light him up. Trauth's maps show we only have the subspecies known as Bronze in Faulkner county. I think we likely have hybrids and have Greenies out in the fields around town.

The striking Rana palustris. A particular spring frog that likes only cool clear streams and ponds and tolerates pollution very poorly. Often associated with caves and mines. Resembles the much more widely distributed Rana sphenocephala, the Southern Leopard Frog. This is the more normal dorsal spot pattern. Some sections of the Ouachitas and Ozarks have spots elongated on the back.

And an even more striking Rana palustris.  Paler and bulkier, makes me think this is a shot of a female from Mellena Driver in west Arkansas. Taken in Dover in July 2011. She has a clear stream near her house. I wish these occurred in my county. Alas, the valley may be too blighted by man for these guys to tolerate anymore.

The lovely Wood Frog, Rana sylvatica. We have our own separate population in the Ozarks. Also an isolate in Alabama and down into the Appalachians. Very early caller and breeder in Feb and Mar in our mountains. Wanders extensively. This one was on Richland Creek in Searcy county. The air sacs are on the side of the body in this frog. Very quiet call that does not carry far.
