Tom, the eastern spadefoot toad is not the same as the "regular" ol' toad, which is the Southern toad. Their calls are different, too. This link is great for seeing and listening to the calls. You can check them both out here. Marcia Here is a link that might be useful: Eastern Spadefoot Toad

It is indeed a male Bullfrog. He has likely taken up at your home due to his disability. They do go to the bottom of the pond and hibernate in the mud, but if there is no mud bottomed pond, you could take him indoors for the winter and feed him crickets. He may be able to hop pretty good, but he is a little bit a lightweight, and I suspect that he has a little trouble feeding himself. This disability may make it difficult for him to take the insects he feeds on effectively. I would try and augment his diet with crickets from the bait shop or pet store and see if he gets a little fatter. You will want to dust the crickets with reptile vitamins. With his injury, he will be unable to fend off predators, and will likely get eaten at a big pond, and if he makes it to winter, may not have enough fat stored to make it through. If it were me, I would take him in and try to make his life easier, but some are in favor of nature taking its course (which would likely be curtains for the frog). If you would like any info about how to help him, let me know; I have kept many amphibians over the years, when teaching Environmental Ed. He may also need antibiotics, to stave off infection in the stump. Unlike salamanders, frogs cannot regrow limbs. BTW: The external ear, called a tympanum, is larger than the eye, making him a male. He has no skin folds from head to groin, which cuts out Green Frog. He has a fold of skin that goes around his ear, making him a Bullfrog. See: Bullfrog on Wikipedia. Enjoy.
