A few weeks ago my dad and I built a feeder for the squirrel as he has already destroyed one of the bird feeders. The design is a simple box with a perspex front filled with peanuts. The lid is hinged so only the squirrels can open the box and all the peanuts are not taken by the birds.
To get the squirrels used to the box the lid was left open. They still couldn't work that the box had food and just used it to climb to the bird feeders. So down came the bird feeders and they worked the box out straight away.
Below is a sequence of shots showing the squirrel using his food box.
