This photo was taken at the bridge near Lee's Ferry...yeah, it looks like a zoo photo, but it's not. Occasionally, these re-introduced birds (with a wingspan of 9.5 feet) perch/roost on the girders supporting the bridges crossing the Colorado river...it is a semi-rare event. This one had turned it's head to look up to me, so what you are seeing is his/her back. This bird is less than 4 years old...more mature California Condors will have a lighter, more reddish head.
