Hi all, Squirrels, grey, don't you just love 'em? I have 6 bird feeders in the garden, 5 I've managed to protect from squirrels, the 6th is constantly destroyed by these tree rats. The feeder is the conventional metal type for seed, which I've repaired more times than I care to count. So now I've constructed a 2" square meshed cylinder, with the feeder suspended in the centre of it. The top is enclosed with the same mesh the bottom again the same mesh on a hinge which closes with a strong spring. The feeder has app 6" between that & the constructed cage. So you'd think that would deter them, no chance. The birds hop onto the outer cage, then onto the feeder. So is the mesh, at 2" too large a hole to stop squirrels getting in? Any smaller & the Bullfinches wouldn't get in. The whole assembly is suspender from a branch on 6 core braided wire, which I lower to top up the seed. The wire is smeared with axle grease, but they still destroy the feeder.
