Swift nesting bricks are hollow bricks that are designed to be built directly into walls, even when buildings are not made of bricks. They provide durable, safe places for Swifts and other cavity-nesting birds such as House Sparrows, Starlings and House Martins to nest, addressing the loss of nest sites from modern architecture. The bricks, which cost approximately £30 each, are a simple, cheap and effective way to provide a much-needed lifeline to one of our most threatened species.
