I was lucky to get this shot when I did last spring. Usually these little buggers are horribly touchy. They fly off screaming like small children having a temper tantrum if you get within 10 feet of them while they are feeding. Interestingly enough however, I have noticed that they tend to do that with other birds too, although much of my experience with these guys spurs from observation of two members of their species over a one month period...
