Queen Elizabeth National Park, Uganda—July 5, 2000
We stopped to admire the hippos in the Ishasha river at one of the campsites in Queen Elizabeth National Park. I took some time to also admire the frogs at the river's edge. They ranged in size from an inch and a half or so to about 4 inches long, and would leap prodigiously when disturbed. And they got disturbed easily; I had to sneak around for quite a while, frogs leaping about everywhere, before I found one that would hold its ground long enough for me to take this photo.
I couldn't find enough information about the frogs in this area to identify this guy until I got a copy of Channing and Howell's recent guide to East African Amphibians. There are a couple of other possible candidates listed in this book, but this one seemed to be a good fit.
