Squirrels and their nuts!

One has to admire the inginuity of Squirrel's. Here are some photo's of a Squirrel attempting to find a way through the defensive barrier of metal bars that surround the feeder.

This particular Squirrel was getting very frustrated and eventually gave up.

However the way to do it, at the end of the day, is very simple. Just do the same as us, take the lid off!
