Its a raid

I have recently set up a feeding station in the garden. A friend kindly donated a large tree branch which I placed in a fence post to try and obtain a more natural back drop to the pics. The good news is that the birds are gradually starting to feed from it. The bad news, so are the squirrels. Today two of hem raided the feeding station. It wasn't long before this chap had his head down the tube.

Whilst occupied by the squirrels, two Mr Robins made an appearance at the back of the garden fighting each other for the rights to feed. Now I am complexed and do not know whether I have been taking pics of the same Robin or an imposter!

Here is today's Robin real or an imposter?
