Jail bird!

This morning, I went down to the allotments where they were holding a coffee morning in aid of Dr Bernardo’s. I spent a couple of hours washing and drying dishes and it was actually rather enjoyable.
I spotted this robin at one of the plots and it looks rather like it is trapped in a cage but I guess the plot holder has put the food behind bars so that smaller birds can get it but not the larger ones like pigeons, rooks and eagles!
