The half coconuts I have which are filled with suet had been lasting for weeks as the birds gradually helped themselves. Occasionally the filling would fall out of one after it had shrunk during a particularly cold night. A couple of mornings ago I found two were empty where they had been half full the previous day. No sign of any fallen fillings on the ground. When I replaced them with a full coconut half I soon found out what was happening.

All in all Birdy Bistro Mk2 is very popular, especially with the cold temperatures hereabouts.
