Working from home today, so kept half an eye on the garden. A Magpie has found a way to get under the net over the pond but can only access a short stretch of bank. I may just leave him alone as hopefully the majority of the tadpoles will stay down the other end and perfectly safe. Meantime another Magpie with a deformed beak has spent the whole day trying to get into the Blue Tit nest box on the back wall. I don't think it can reach the chicks but it is driving the poor parents to distraction.
