This female Northern Cardinal showed up at my feeders yesterday 3/4/19 and returned again today. I don’t know if this is a sign of disease or if it is just an anomaly. She acts quite normally and seems to be accepted by all the other Cardinals in the group.
I saw precisely the same today, also a female, affecting both eyes, at VA arboretum near Boyce. 11/27/20
