I managed to capture this great little video of the activity that has been going on all day outside my window. 3-4 hummingbirds at a time are fighting over the feeder, mostly females. All of the ones in this video are gals - very fiesty gals.
See how they fan out their tailfeathers, to make themselves look big and menacing. They sometimes hit the window or bang into the feeder when fighting. I sometimes feel bad that they are fighting, but it's just the way that they are. We have 9 feeders out in our front and back yards, so it's not like they are starving. But this one seems to be the busiest, although fights break out now and then at each of the other feeders. Maybe this one is popular because it's up on a 2nd floor window with lots of tree branches nearby. You can see them sitting in the branches watching the feeder for invaders.
The video is 1-1/2 minutes, and I thinks it's pretty cool. I am now a wildlife photographer/videographer.
That weird orb/UFO that you see is the ceiling light behind me, reflected in the window.
