Great spotted woodpecker.

They've been back every day after I put some monkey nuts in one of the feeders, but only if the kitchen window is closed, so this was taken through the window. Yesterday, I retrieved  a limb from one of the conifers that came down in the winter storms and planted it next to the feeder. Perfect for photos. I think there are at least three in the family. 

I may have made a mistake. It could be a juvenile Great spotted woodpecker. I'll wait for Diane or Kwchas to confirm the ID.
