Saving Swifts: A Brick for the Birds - Hannah Bourne-Taylor - BS133
Apr 22, 202501:21:26Tap to summarizeSwifts are among the most remarkable birds on Earth — they sleep on the wing, migrate thousands of miles, and return each year to nest in the same tiny holes in our buildings. But as we insulate, repoint, and renovate, those nesting sites are vanishing — and so are the birds.This week, Jeffrey speaks with Hannah Bourne-Taylor — author, activist, and the powerhouse behind the campaign to mandate “swift bricks” in all new UK homes. From raising wild birds in Ghana to walking naked through Westminster with painted feathers, Hannah’s journey is as bold as it is heartfelt.Full Show Notes: https://www.buildingsustainabilitypodcast.com/blog/saving-swifts-a-brick-for-the-birds---hannah-bourne-taylor---show-notes/Support the early day motion (MP action)Find your local MP Hosted on Acast.
