Could you elaborate a bit on your description, Roy? I'm not
clear what you mean by "banner marks viewed in the ventral
position." Do you mean as in the squarish dark carpal patches on
Rough-Legs? Or the patagial marks on Eastern Red-Tails?
Also, are you saying the entire primaries, not just the tips,
were black and the rest of the wing uniform gray, not two-toned,
and with no dark trailing edges to the rest of the flight feathers?
How about the tail?
I live near there and there has been a beautiful adult male
harrier around for the last week or so. It couldn't have been
that, could it? Light conditions can make the bird seem a darker
