I had trouble uploading this last night, so it's a bit late. I was watching the garden when two Great Spotted Woodpeckers arrived at the same feeder. Normally this means a bit of aggravation followed by a lot of posing and a noisy dispute.
After a short while the adult moved up and stretched up towards the young bird. The beak on the juvenile is noticeably smaller than the parents beak.
The young bird leaned down to received the food that was being offered by the adult bird, a male thith a bit of red on the nape.
