If proof were needed

That pigeons are not that bright then these two prove it!  They built the nest a few weeks ago, then in the wind last weekend it slid (you can just see the part that slipped bottom right) and the eggs fell out.  They are now trying to nest again on the same wonky nest in the unseasonably strong winds.  Another one seems to have got himself "stuck" behind a neighbours shed, or just keeps flying in there.
