Or a juv Great Spotted Woodpecker? (juvs had red crowns) A few weeks ago my daughter called out that there was a strange looking duck making a funny quacking noise on the grass in our garden - it was a juv GSW!!

First time I've seen a GSW on the ground and it did look rather odd and out of place there. I'm more used to seeing them shimmy down the tree trunks to the feeders
