Each day we put out nuts for the birds. The feeder is suspended from a hook on an isolated metal rod. Even so, the squirrels climb up the rod and unhook the feeder so that it falls to the ground where it is even more accessible! But the feeder is round and however much they push it around the nuts remain at the lowest point and furthest away from the side and virtually impossible to get at. Meanwhile the blue tits look on - resenting the intrusion and waiting their turn.
