I often shoot frogs and snakes while waiting for birds and here's one recent bullfrog portrait.
They almost always face away from the shoreline and will sit for hours waiting for food "to pass by", just like me waiting for birds to pass by.
Hey Dave, great close-up and agree with Robert about the lighting. I carry a diffusser to shade these guys, and it can be held far enough away as not to scare him off. The colors are much richer in the shade, but then you lose the great catch light you got in the eye. Well done.
