One of our neighbours had new soffits and fascias over the weekend. We got home to find that the workmen had therefore blocked the gaps where sparrows used to get in (would it be to the roof?) and were nesting. Since then (Saturday), a couple of sparrows have been flying about, settling on the gutterings and then pecking at them, throughout the day. I wondered if they could hear their babies but can't get to them. It's made me sad to think of it. AIBU?
