It was delightful. I guess they're like any other creatures. If there are always lots of people in their environment, they learn that they are not going to be harmed and lose their fear. In an idyllic setting like that, that is a good thing. It probably wouldn't be so good for birds to become too tame in a residential neighborhood. There are too many variables.
The birds around my feeder congregate in nearby bushes when it is empty, and as soon as they see me open the door they all start calling. Soon the nearest bush is heavy with birds – about 4’ from me. It sometimes reminds me of the Hitchcock movie.
The squirrels wait patiently (so far) at my feet for the handful of peanuts I drop.
