No problem! They can have some variation in color, all of your images are very nice.

You know, with the unique markings I wasn't sure if they were different species or not. But after looking into it I am sure you are right. Especially after reading an article which stated juveniles "chirp" then retreat into the water when startled. This was definitely the case. Thanks once again!

It looks like all of your recent frog photos are of American Bullfrogs, Lithobates catesbeianus! http://en.wikipedia.org/wiki/American_bullfrog
