Most hummers are aggressive; it's in their nature. They are very territorial and part of what we perceive as aggressiveness is just what they do to protect their perceived territories. I have loads of them. They are competitive as all heck. They try to prevent one another from eating at the feeder. Every now and again, I'll have a few who eat at a feeder at one time, but with 5 feeders out in a relatively small area, there should be plenty of nectar for all. The hummers around here are so in tune with everything that they keep track of when I change the feeders and put cool nectar out, and they are right there as soon as I've put the feeders back and gotten out of their way!

Thanks for sharing that is a lovely photo of the bird.

Great photo Al

Wrennie are your hummingbirds aggressive this year?  They have been a joy to watch this year.  Dale
