Squirrels being a Pain

The squirrels chewed through one of the feeders on the weekend. This is really annoying as this was the feeder I was using for some flight observation that I have recently been doing. I have replaced the feeder with another one that I hope will be more robust and more squirrel proof. However this feeder is not as good for observing as it does not have perches. The squirrels are very agile climbing up the slippery pole to the seed and clinging on. When they have been there for a while they start to slide back down the pole but quickly climb back up.
