Nictitating Nuisance

I normally don't post images of birds on feeders, (OK, I have a few times), but this one caught my eye. I seem to be catching a lot of birds blinking recently. I really wish I knew how NOT to attract these birds, because when they arrive, they come in pretty large numbers, and they drive the other birds off my feeders too. I'm going to see if I can find some seed that my songbirds like, but these critters don't.
