Sorry, it was too quick for me to photograph it.
It has been mooching about in my garden and likes to hang about near hedges and small trees.
It was roughtly the size and shape of a large female blackbird, but rounder and fuller (albeit birds are sligtly puffed up in this weather.)
It was about the same height but I would say slightly chunkier.
It was slightly lighter than female blackbird brown and had a slightly speckled breast. I could not see any distinct clour on the breast apart from straw colour and mottled dark brown.
It has distinct slim yellow circles round its eye sockets. This feature really stands out.
I thought it may have been a redstart but it is bigger than that.
I am unable to tell you the colour of the beak or legs, but if they had been a bright colour I would have noticed.
I have not heard it call yet.
I cannot find reference to this bird anywhere.
If anyone can idetify it from my description I would be very pleased.
