That was taken with a superzoom camera a friend of mine owns. I have debated getting one myself, but I wonder if I would be better off getting a real camera (one with a lense and whatnot).
Last year there was a female who was super territorial over the feeder I put out. I would watch her sit in the nearby tree. She would just watch the hummingbird feeder and fly over when another hummer came to scare them off. XD
I put out two feeders this year in the hopes I will get more hummingbirds. =) We'll have to see what happens as I am at a new house so I don't know what their habits are in the area I am in.
