Bird feeders empty on The Lodge webcam

Ive been noticing since yesterday that on The Lodge reserve webcam that the birdfeeders have been getting very low and now they are empty. It's very unusual for the RSPB to let birdfeeders at any RSPB reserve go empty. So I'm now wondering why the birdfeeders at the RSPB reserve The Lodge are now empty?

Regards,

Ian.
