There were some people feeding the ducks that live at that pond, and they said it was fine if I came close enough to get pictures. I think I got a lot of good ones. Ducks are pretty friendly, not exactly camera shy; especially when there's someone with bread in the vicinity.

The white duck in the center was particularly fierce when it came to defending what he considered "his" bread. This photo looks like he's telling off that mallard for intruding on his space.
