"Bird-friendly bricks
Swifts have made their homes in cracks and crevices of our buildings for thousands of years. But the style of modern construction has helped put populations under pressure. The swift nesting brick, developed by Manthorpe Building Products in conjunction with the RSPB, is a bid to help the birds during the summer when they stay in the UK to raise their young. The bricks feature sheltered tunnel entrances and drainage holes and provide a safe area to allow swifts – clean and quiet house guests – to nest."
