I do feed them John. I feel like I have one that comes every year and he is hogging or overly protective of the feeder. I keep seeing others come to check it out and then one comes down from the tree outta no where and runs it off. Like hes protecting the feeder.
So I put up another one about 20 feet away.
Then to blow my theory out of the water, a couple weeks ago, I saw two of them on the original feeder slurping next to each other.

During the summer I'll have to fill the one feeder every other day.
Love watching those crazy hummers.
