We have 6 hummingbirds (3 pairs) that return here every year. They are always aggressive, but this year seem to really be much worse than usual. I have more than one feeder and they usually will fight over one feeder for a few minutes and then split up and go to the different feeders. Yesterday I was sitting out on the porch and they were fighting over one feeder for HOURS. I took a few pictures of them and thought I would share. In the last photo, I was able to get 5 in the picture. They will go over and sit in the butterfly bush (photo 1 & 2) or in the corkscrew willow tree and watch. As soon as another hummingbird approaches the feeder, they zoom off to fight. Their sweet appearance is deceptive !!!
