Thanks armdog! I got it from tong garden centre 60 quid I think it was, its got sound and night vision too. Next doors got a cat and the bugger sometimes tries to climb the tree. Last year the bluetits divebombed it loads of times. They even kept the wood pigeons out of the tree. As soon as last years blue tit chicks fledged a pair of wood pigeons nested in the tree, they built the crappest nest iv ever seen literally took them 24 hours to build. They never fledged anything and I found there eggs in the grass!
