Bird nesting box (West Moors BH22)

Used for three nesting seasons. Mixed results ... one successful, one attempt at raising but abandoned (lack of food) and one no result. We're not trying again as the only place we have to use is too 'open' (no cover for protection of parents monitoring box) and too 'busy' with larger birds and human activity close-by. As can be seen, box can be easily accessed for cleaning. The diameter of hole is designed for blue tits or coal tits - we had blue tits on any attempt.
