Just happened to be walking by the church yesterday evening and captured this on my phone, quality is okay, but not brilliant, apologies. Fantastic air display in its own right. I'd like to see the Red Arrows perform a display in these numbers.... now that would be a sight to see. Amazing sound coming from so many martins.

I was down Newhay a few weeks back. Daytime. Sat and listened to a bird (don't know what type) singing away on a nearby branch for all it was worth.
Mesmerisingly beautiful.
