Tawny Owls, Stock Doves and Jackdaws naturally nest in dark cavities in trees or buildings. Such sites are often in short supply so this nest box can be a valuable way of helping these species.
Research has shown that it helps to add a layer of loose dry material such as wood shavings or shredded bark to the nest box before the breeding season starts, which may be as early as January for Tawny Owls. In an exceptional year Stock Doves may still be nesting as late as November, so the best month to clean the boxes is December. The front of the nest box is hinged and secured with a latch, so cleaning is simply a matter of opening the front, removing any contents and replacing the shavings or bark.
