Come and live in my house. I had two pairs of them nesting in my roof, plus chicks, until they fledged recently. They learned to tolerate me working in the loft, reinforcing ceiling joists. I left them alone and, eventually, they all flew the nest a week or two back. They're still hanging around outside though. I've seen pretty large murmurations a few times in recent years (this is in East Anglia).
