An interesting thread but missing one element, that of the “universal” nest site concept.
Integrating swift bricks in new-builds was always going to be problematic if they only benefited one species; planners/developers could argue “what about other red-listed urban species such as house sparrow and starling?”, so work showing that swift bricks were also used by house sparrows, starlings and other species was significant as it allowed swift bricks to be reclassified as “universal” nest sites, making them far more difficult to argue against. This, of course, led to the publication of the British Standard BS 42021:2022 “Integral Nest Boxes – selection & installation for new developments”, a game-changer when it comes to getting swift, sorry, universal bricks conditioned.
In Derbyshire, if the biodiversity officers request compliance with BS 42021:2022 in their consultation response, then this is automatically conditioned. Relying on the presence of swift nest sites to justify swift bricks is not optimal and ecologists doing this should be gently guided towards BS 42021:2022.
Finally, if we accept the universal nest site concept, then surely the stipulation that bricks should be 5 metre high or more becomes less relevant as many of the species that may use these bricks are less choosy about height than swifts…
