I took several pictures of the hummer's feeding. The best I saw was about 11-12 (a few of those 12 were waiting their turn a few inches away) but all on one feeder. However, it was past dusk so the lighting wouldn't have shown them well enough had I tried to take a picture. Just looking at this picture, I can still "hear the whirring of their wings" as though I was sitting there in person.
