Here is one of the birds in a rare moment at the feeder alone:
Here is the other bird, also at a rare moment alone at the feeder:
I love the hostile look on the hummer's face. Clearly does not want to share.
In fact, I think I can take you on:
Yeah, you and who else?
The two of them go at it, swirling and rising and falling.
A shaky peace is reached for a while, but each bird briefly challenges the other periodically.
Suddenly, a third hummingbird enters the scene. I don't think this is going to work. The bird on the left is not going to stand for this.
So now we have three birds involved. I wonder how such activity can be in the hummingbird's best interest? They have a very long migration ahead of them and hardly anyone gets any nectar this way. No one seemed willing to give up the conflict and come back later.
It was quite a sight to see, probably the longest hummingbird duel I've witnessed.
