Yeah the whole thing (no pun intended!) is interesting, and I'm not sure how much credence we can give the various studies. That is one of the stats that jumped out at me from one that I read, where they had actually put boxes with different hole depths around and they seemed to favour the deeper ones. Truth is that in nature they will nest in all sorts of nooks can crannies I guess, and as we all know they are more than happy in most of the standard wooden models. I'm sure the single most important thing is location/position - that could include the fact that they prefer a neighbour's garden fulls top, for better food or whatever. The nest box "my" birds used last year was a very old (knackered), small wooden box mounted on a shed in a neighbour's garden about 1.8m high, mounted very openly and just facing the lawn.. By rights my boxes should have ticked all the boxes, but the birds weren't having it!
