I'm not sure I believe either point. There are Anna's in my yard because
I have a feeder out but if I didn't they'd just go down the block, not
to Mexico or wherever. I just can't believe our use of feeders has led
to the Anna's Northward migration. I had a 10 minute chase this morning
around the house, lots of action in front of the windows. Pretty cool.
