Top two photos are of one of the cricket frogs we saw today. I love cricket frogs.
The next frog is most likely a bull frog. He was a long way from me and I had the camera zoomed out to maximum. We observed him through binoculars and did not detect the presence of a lateral fold extending beyond his ear. Also, he had a big, fairly blunt head.
The last frog is a green frog. Again, the camera was zoomed out to max. I stretched out on the (WET) ground to try to get a steady shot but wasn't too successful. Oh well, I don't really care -- I just wanted to show you the frog!! :)
