Got really close yesterday. They are showing much less fear this year. Has me a bit concerned though as one has been killed by an eagle and another injured and sent to the recovery centre already and the season is still young ( November 30 / 2010).
Stats: Canon 50D, Canon 500mm with 1.4X, 1/60 sec at F/6.3, ISO 1000
Love the stare and talons! BG is almos as the bird's plumage!
A few things I would do to improve the image if it was mine.
1- Would try to maintain a 3:2 ratio giving more room on right.
2- I would increase the color temperature and contrast
3- Would try to shoot this image from a lower position (if possible and is not going to scare the bird away!)
There seems to be some motion blur on the tail feathers, not much you can do there! All in all a wonderful image!
