I'm currently knocking out a bird table. I hate pigeons and I don't want them getting to the food which will be there for any other bird except pigeons. Therefore I intend to put up vertical dowelling between the table bit and the roof. The question is: what should the distance between the dowels be if a blackbird is able to get through but a pigeon is to be utterly frustrated?
