What a beautiful close up, an intimate meeting indeed. Was the hawk really sitting close to you? They are usually so shy and wary, seeing them nearby is always an experience. I like how stunningly red their tail still is, even in the foggy grey weather!
I do not have a telephoto lens, but I do have an optical zoom, I was within 6 feet of the hawk. Twice - I like this the better of the two, because it feels more personal and the red tail as you pointed out. M
