Preening macaws

We so often see macaws in zoos and bird parks that it's hard to believe they actually live in the wild.  But they do.  In Brazil, there is a giant sinkhole in which about 50 mated pairs of red and green macaws make their home. A platform has been constructed on the rim 300 feet above the bottom of the hole for people to watch the constant activity of the colorful birds. For this shot, I was looking far below my position to photograph two of the birds preening each other. They were perched on a branch about 100 feet down the wall of the sinkhole. I took this picture with a Canon 500mm f/4 telephoto along with a 1.4x teleconverter giving me 700mm of focal length. My settings were 1/640, f/8, and 1250 ISO.
