Red-Eyed Tree Frog, Tortuguero National Park, Costa Rica.

When I was in Tortuguero National Park in Costa Rica quite a few years back, I discovered an army of red-eyed tree frogs behind the lodge that I was staying at (I’m told that’s what you call a group of frogs — an army). The males would start their mating calls every night just before I headed in for dinner. Needless to say, I was always the last one to eat at that particular lodge. Nikon D200 with Nikkor 70-200mm lens (at 270mm with Canon 500D close up filter attached) ISO 100, f/20 at 1/60th of a second, two Nikon SB-600 flash units.
