I keep squirrels out of my bird feeders. Take one piece of 4 in round, 12 feet tall piece of pvc pipe. Set it into the ground. On top place a T connector with caps on each end. This keeps birds from going in and falling down the middle of the tall pipe. Attach a couple pulleys small rope and attach bird feeders on to that. Oh yes a cleat to attach the rope to. Its fun watching them try to climb the pipe. . Just watch any bushes you have planted at the base dont get to tall as they will jump and climb the rope.
