Socks on birds

Outside my window I watched a robin come to a skid ding stop on a bare limb. He didn't need socks. The towhee that has been coming to the feeder for a long time is gone. The last few times I saw him he was missing all the feathers on the top of his head. I should have knit him a black hat.
