Hanging a nesting box in the garden: three mistakes that you should definitely avoid. Nesting boxes not only create new habitats, but also enable bird watching in your own garden.
Many species, including black redstarts and swifts, seek proximity to humans and like to breed in their own garden - provided the nesting box is hung correctly. When hanging up nesting boxes, you should also consider protection from predators. Certain devices can keep predators away: Cat repellent belt for the trees, Smooth bars for the nesting boxes and a pole of little use to the entrance hole.
