IS this unusual? I thought it was a strange kind of bird on our nut container hanging from the tree in the back garden.

On closer examination, I saw it was a grey mouse, clinging to the wire and having a feast.

Does this mean I've missed seeing it before and that I'll have to stop putting nuts out for the birds, or we could be infested with mice? I am rather worried now.
