I have one of Sam's tail feathers that has fallen out normally. Shaft looks nice and healthy and I was admiring the pretty yellow and how it blended into the black at the end. But then I flipped it over and was a bit surprised to find that on the other side.. where the black would be, it is a very pretty dark blue. Sam is a dominant pied green series and the only blue he has on him are the little patches below his cheeks. What does this mean? Is this usual or does this mean he has some sort of split in him? Is it possible that the change in color is based on one side being exposed to sunlight more than the other? Thanks guys!
