Today I was looking at a couple of images I took two years ago, around Christmas time, up near Twin Falls Idaho. My brother had told me about an area where he had seen a bunch of Bald Eagles flying around and suggested we go take a look to see if they were still there.
I believe there were approximately 40 American Bald Eagles flying around at the time I took this. Most were too far away. The first image below was shot with the Canon 100-400mm lens at 400mm and cropped in from a 21mp image from the Canon 5D Mark II.
The challenge to wildlife photography, of course, is patience and perseverance. You can't tell the bird, fly this direction, in this lighting and look this way. Oh .. and could you PLEASE come closer? (I don't think it matters how long your lens is, it's never long enough when shooting wildlife)
As the sun was setting, I decided to capture the birds up in the tree together with the sunset. I believe I counted 15 Bald Eagles in this tree:
