Great capture, lucky you to see them so close with your own eyes, they're a magnificent creature. (a little more room below the feet would've been nice but it's still a great shot.)
Thanks for the comments . Yea, should have had a bit more at the bottom . What a thrill it was to was to see this big boy so close. He was maybe 100 feet from the road, just casually feeding. And I had just changed over to a 28-135 zoom. Got to get lucky once in a while !
