I used to live in a house and had a big backyard. I catered to the birds with numerous feeders and a fabulous garden. For the hummers, I had butterfly bushes and tons of other flowers that they liked plus feeders and I never had an issue with one bird claiming a feeder. Now I live in an apartment and decided to put up feeders on my balcony. Originally, I only had seed feeders but I kept seeing so many hummers that I decided to hang a hummingbird feeder for them too. I had hummers at the new feeder within 5 minutes. For the first few days, several would eat there peacefully together. But then my tiny bully decided to claim the feeder as his own and began running everyone off. He literally sits on the rail below the feeder or perches on top of it all day and night and anytime another bird tries to come near "his" feeder, he chases them off. (he's a Ruby Throated male)
So I decided to hang a second feeder so that the other hummers would have a place to eat and he could have his feeder to himself. I hung it on the opposite side of the balcony so that it would not be close to the little bully's feeder. To my surprise, he has now claimed BOTH feeders! He zips back and forth between the two and chases off anybody that tries to land on his feeders. I'm so frustrated! I love my tiny bully and enjoy watching all the air acrobatics when he's chasing others off, but I just want all the hummers to eat in peace. I've got about 8-10 who come daily, but only 1 gets to eat. Is there anything at all that I can do?
If you have windows on a different side of the building as the balcony, and you can SAFELY open a double window to hang a feeder on the other, perhaps you can hang a window feeder. I really like the aspects gem feeder, but if you buy a suction cup hook you can hang any feeder.
