Hunting on the lower east coast from a 14’ jon boat, I don’t kill a lot of redheads but killed one a handful of years ago that had a dark, inky red head. I noticed it but didn't think much about it. A friend that hunts from a scull boat sent me a picture of a similar bird he had killed this past season. I reviewed some of my redhead pictures and found one, maybe two, in a photograph in a flock of 12 that I photographed during a cold spell a couple of years ago. Has anyone else noticed anything like this?
