Owls

The Barn Owl Box, £340.

This one has a history. Rob mounted a display sample in the oak tree by the gate, in what everyone agreed was far too busy a spot. Barn owls moved in anyway. They were only put off when a BT engineer up a cherry picker started pruning and reported that two big white birds had just flown out of that box thing.

The box went into a quieter tree. There have been five broods since, and it is occupied now.

So the honest advice on siting is that owls are less fussy than the books suggest, but they would rather not share a tree with a chainsaw.

One size, made to be left up for years.
