November is a great time to see large flocks of Blackbirds at the Sequoyah National Wildlife Refuge in Oklahoma. I see a lot of Red-winged Blackbirds in my photo. I read that the Common Grackle, Brown-headed Cowbirds and Starlings could mix into these large flocks.

I was driving the auto tour road near the entrance to the refuge and these Blackbirds were in the road. I got out of my pickup and braced my camera and lens on the door frame of my pickup.
