I have this Red-winged Blackbird, and it seems to have some issues. From what I understand about leucism in general, #1: It is usually not symmetrical, and #2: It always is a lack of pigment in an ENTIRE feather, not just part of it. Are these assumptions correct? I'm trying to decide what has caused this. It seems to have red feathers with white tips. It is also perfectly symmetrical. It has also been this way exactly since April 14th. Any ideas?
