Swift Brick??

Hi 

I've just joined this forum. I've been a longstanding bird-watcher (if not, birder). I was once part of YOC, now a member of RSPB.

They emailed to say Help Us Save the Swift, which of course is the right thing to do. They showed a Swfit Brick, as one of the new nesting options they want us to support. I would be interested in putting a Swift Brick under our eaves. The RSPB shop only sells, Swfit Boxes, which are made of wood, and don't look nearly as attractive to visiting swfits. Surely the RSPB shop should sell Swift Bricks too, as they are being heavily promoted in the Help the Swift campaign..

Does anyone here know where I could buy a Swift Brick?? 

Thanks for looking.
