He is stunning. I've been trying for raptors around here lately and have generally failed. I havent the patience to sit in the bush for hours waiting and when I do see one, by the time I stop the car, its found its lunch and disappeared.
I've found good wetlands shooting sites in several areas of the country where I've lived. I recommend finding the closest one that has a good variety of wildlife, and giving it several hours a week, preferably all on one day. I rarely sit and wait for the animals - mostly I see where they are while walking, and from there it's a matter of patience in getting close enough to shoot.
In Akron Ohio I like going to the Ira Road Towpath and walking left to the wooden walkway. Lots of species from small to medium birds, ducks, geese, beavers, etc. etc.
In Huntington Beach/Bolsa Chica, I've worked the walkway over the canal, which has many birds going overhead and perching here and there. But mostly I'd walk the 1.5 mile path in and out, to see a huge variety of species - birds, snakes, coyotes, ....
In Charleston SC, my favorite is Charles Towne Landing, which has a low per-year fee. It has quite a variety - birds of many kinds, alligators, turtles, snakes, exotic spiders, and so on.
