This male has been coming to my feeder all winter. At first I thought he just had extra white feathers around his eye. Now it is clear there is something very wrong. His feet are huge and scaly, and his eyes are worse. He still flies around and eats well- no way I could catch him that I know of.  Does anyone know what's wrong with him? Would it be contagious?    The others are all fine so far- at least  1 other male and 2 females.
