Acting casual and disinterested while slowly, indirectly edging closer can get you pretty close if you don't look at the bird. They've got a pretty good sense for when they're the subject of attention. It's also worthwhile to pick a spot you like and just wait there for a while. The longer you're a nonthreatening fixture of the environment, the closer they'll come to you.
