[QUOTE 4615199, member: 9609"]I think I just presumed the DPC was just to stop rain getting through the join at the back (I have done the same with some of my bird boxes)
I will have another look when I'm up there next week to see if it is hinged - and yes it certainly looks like a squirrel feeder, but it would be very odd if it was, this wood has been heavily infected by greys and is at the greys southern most boundary in the borders. Gamies are trying to exterminate the greys in this wood.[/QUOTE]
Maybe that's why it's empty?.
