Swifts like high, deep crevices to nest, but because we’ve lost many old houses and buildings, and as roof spaces are filled or mended, their numbers have declined dramatically and they are now on the UK Red list of conservation concern! Fix a wooden swift box to the outside of your home, or install a swift brick, to give them somewhere to nest 💙 #WorldMigratoryBirdDay #WMBD2022 #Conservation #UKWildlife #Swifts
