I'd be very interested to see any reliable, documented evidence of Northern
Goshawks with "red-orange vermiculating under wing &/or breast patterning."
Until such evidence is forthcoming...........well, let's just say that I
don't believe that Martians in flying saucers migrate through our
atmosphere, either.
