Swallows.......I'm not too far from where you live and must admit, I have seen a noticeable decline in the number of swallows in the last 3/4 years. This year I was getting quite worried as it was very late when I first spotted them, although that could have been the weather conditions. Last week I noticed just a few more flying about.. Anyway,it is probably more to do with their nesting sites too. Houses are repainted with modern paints, barns and out buildings re-developed, converted or demolished. The farm opposite us has been developed and there are few places left suitable for them. I think it's a great idea of yours ,anything is worth giving a go, and if it works, it was worth it. I so admire and love the little swallows, such strong, ,little creatures.
Just one thing, is it better to leave the previous years nests in place for the following year, or should they be taken away?Anybody know?
