These were almost backlit behind a thin cloud cover with a foot of snow still on the ground, I just exposed for the birds and was kinda surprised at the results, D300 500 f4 + 1.4 tc cropped about 50 % I was back there today and saw 6 mature and 2 immature birds but the clouds are gone and just couldn't get the exposure right today. So I guess I gotta go back !
