What a beauty!
My mother used to live on property that bordered the Bear River just north of Sacramento, and there were swarms of Black-Chinned Hummers with their brilliant purple throats. My stepdad would fill three of the big feeders four times a day for the little guys. I used to sit on the stairs leading up to the roof and watch them, and sometimes I'd find myself in the middle of the swarm.
Oh, to have had a camera!
You may not have had a camera, but you still have the picture.
That sounds really neat. When I get swarmed it's usually seagulls. 8>) I have a roll of 35mm around here somewhere of pics of about ten grey jays chasing my son around up at Mowich Lake trying to get his sandwich. I wish I knew where I put that.
