They are fearless little things. They could care less that I am sitting mere feet away.
I have noticed a change in their behavior lately though. I think maybe because they sense that fall is coming on and they are feeling the need to stock up on energy.
Where I mostly used to just see the colorful males, I am now seeing females and juveniles also.
They are constantly at war with each also. Sometimes as many as five at a time will soar and swoop or shoot straight up into the air like miniature helicopters. At times they actually bang into each other. I can hear the dramatic little thunks when they slam their bodies against each other.
