Plenty of falconers keep their bird on 1/4 acre plots in the suburbs. And many have even converted their deck in a second story apartment for raptor housing. That's not really the issue. The important part is finding places to HUNT the bird, because that's what falconry is: hunting. Overgrown plots in industrial areas offer alot of game for a suburban falconer.. rabbits, rats, etc.. And I've even seen falcons flown on ducks out of a pond in front of an office building on the weekends!! Join the Washington Falconers Association and get in touch with a few falconers up there. WA got alot of really good ones. You'll get a chance to see their facilities, but unfortunately the seasons coming to an end so you may not see much in the way of hunting and how to find good hunting spots until next Fall. But at least it'll give you an idea.
