Even your squirrel pix are better than mine.
My bird feeder pole has a squirrel baffle on it, essentially a can, about 18 inches high and 6 inches in diameter, open at the bottom but closed around the pole at the top.
Most of the time the squirrels are satisfied with the seeds that the birds drop on the ground, but every now and then one of them tries to climb the pole, dead-ending at the top of the baffle with only the tail hanging down. It always turns around and scoots back down the pole before I can grab my camera.
