Tawny Owl Nest Box

Any point attaching one high up on a house over looking a wooded area ?

We have plenty of Tawny Owls about, often see them sitting on the roof, and we hear them all the time.

I have recently attached it to a tree in the wooded area, but there is a path goes by and yesterday some inquisitive children were trying to through stones into the entrance hole!  So obviously where I have put it is not going to work!

this would be the view from the entrance hole
