NOTE 1 There are a number of other bird species that nest in cavities which could be accommodated in integral nest boxes.
This British Standard does not cover installation of:- i) integral nest boxes in buildings where the surface is primarily glass, as glass surfaces present well-known and fatal hazards for birds, or in metal-framed buildings with any form of insulated or fire-rated cladding; and
-
ii) exterior bird boxes.
NOTE 2 Examples of species that might breed in external nest boxes in the built environment include little owl, barn owl, tawny owl, kestrel, peregrine, stock dove, jackdaw, black redstart, pied wagtail, spotted flycatcher, robin, wren, tree sparrow, swallow and house martin.
NOTE 3 For other species using exterior bird boxes, a competent person can advise on the species of bird that are present and suitable mitigation for them. Expert advice is also available from Royal Society for the Protection of Birds (RSPB), British Trust for Ornithology (BTO) and species-specific groups, e.g. Swift Conservation, Action for Swifts, Hawk and Owl Trust, Barn Owl Trust, Wildlife Trust, Wildfowl and Wetland Trust. See Annex A for a list of relevant sources of advice.
