Nest box positioning
What is the best position / placing for nest boxes please?
Is there a maximum height for them? Do they need to face in a particular direction?
We have a small garden that has many bird visitors on a daily basis. Last year we put out some sheeps wool in a peanut feeder and the Blue Tits used some of it but disappeared elsewhere.
Having developed a love of watching the birds in the garden we would cherish them nesting there but current boxes have stayed stubbornly empty!
Any advice gratefully received.
