Just cleaned mine out. Last year a wren spent 3 days building a nest in there and then buggered off......why ?

Very disappointed right now, I expected something a lot more different to be spoken about
Probably disturbed- usually by a bigger bird. If y'hole is bigger than the nesting bird, it allows bigger birds in.You can buy metal plates to reduce hole sizes if you want blue tits and smaller birds only. (I've got a big one!)
I think I read somewhere that a male wren may build up to 3 nests & the female will choose the one she thinks will suit her best. I maybe wrong though.
I think that's right. Also, wrens will nest in open-fronted boxes, so my suggestion about hole sizes was wrong. The RSPB site says that a 25mm hole serves blue,coal and marsh tits; 28mm serves great tits and tree sparrows;32mm does for house sparrows and nuthatches and 45mm for starlings.

What about Robins?
Also how high do the boxes need to be off the ground?
