The bullfrog is native to eastern North America. Its natural range extends from the Atlantic Coast to as far west as Oklahoma and Kansas. It is not found on offshore islands near Cape Cod and is largely absent from Florida, Colorado, Nebraska, South Dakota, and Minnesota.
It has been introduced into Nantucket island, Arizona, Utah, other parts of Colorado and Nebraska, Nevada, California, Oregon, Washington, and Hawaii.
In these states, it is considered to be an invasive species and there is concern that it may outcompete native species of amphibians and upset the ecological balance. It is very common in California, where it is believed to pose a threat to the California red-legged frog and is considered to be a factor in the decline of that vulnerable species.
Other countries into which the bullfrog has been introduced include Mexico, the western half of Canada, Cuba, Jamaica, Italy, the Netherlands, and France. It is also found in Argentina, Brazil, Uruguay, Venezuela, Colombia, China and Japan. The reasons for introducing the bullfrog to these countries have included their intentional release, either to provide a source of food or as biological control agents, the escape of frogs from breeding establishments, and the escape or release of frogs kept as pets. Conservationists are concerned the bullfrog is relatively immune to the fungal infection chytridiomycosis and as it invades new territories, it may assist the spread of this lethal disease to more susceptible native species of frog.

not pos it isn't pigfrog; in a marsh in dry prairie off of All Weather Road at Myakka River State Park in Sarasota, Florida
Local wildlife. Taken through some dirty glass at what used to be a pond for turtles. I'm not completely happy with the clarity, but the POV was quite an opportunity!
Fountain Creek Regional Park, Fountain, CO - I don't recall seeing wild frogs before. I've heard them plenty of times, but these were just as silent as could be and easy to miss too as they hardly moved at all. I sort of guessed at the identification but am pretty sure they are bullfrogs as I didn't see any other similar candidates while hunting around ...
So nice to hear the deep base booming of the bullfrog. Even nicer when on can locate them in a place where one can get a photograph.

American bullfrog (Lithobates catesbeianus) - Pitt County, North Carolina
I tried to get creative with this shot of a bullfrog the other night, not perfect but I'm still rather pleased with the result. These large frogs eat anything that will fit into their mouths including other frogs, various invertebrates, small mammals, birds, etc... This one was too small for birds and mammals but I'm sure would happily munch on any smaller frogs or inverts. Based on my observations I suspect that atleast some of the diet of the frogs in this area consists of crayfish. I managed to sneak up on this frog and take this shot, I tried to adjust for the next one but it decided it had enough and swam off.
Driving along the Notom-Bullfrog road you'd hardly know this oasis existed. You get a glimpse into the canyon from time to time but it's so deep that you can rarely see down to the bottom. All you see is some desert in the foreground, then a bit of rocky canyon wall with the Henry Mountains as a backdrop. Stopping the car and walking a bit closer reveals the oasis at the bottom.

June 8: Bullfrog to Boulder Mountain, with a walk on the Waterpocket Fold.
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura The oldest fossil "proto-frog" appeared in the early Triassic of Madagascar, but molecular clock dating suggests their origins may extend further back to the Permian, 265 million years ago. Frogs ...

Thanks for looking!
Bullfrog-looks like lunch is inches away! Check out the fly at the corner of his mouth!!
Another day out playing with the Macro lens.
They are doing very well for an invasive species. There were two of them out on the mud flat measuring at least five inches and bellowing out their mating calls.
