Definitely not a Chaffinch. It moves its wings
It has two flanks of white on both sides of its body. Unless Chaffinches breed with Dunnocks.
But its always in the garden and the Robin chases it off. We also have two robins now and they do not fight
The above is in reply to the first description –
We have in our gaden a bird that is very much like a Dunnock, but it has white feathers on both its wings.We have Dunnock, robins chaffinches and the usual birds. But only this one has white feathers.Can you tell me what kind of bird it could be, if not some kind of Dunnock
I’ve tweeted it and will take a look at some bird books and ask a few friends.
