For the second evening running a brief but spectacular display of Swallows around 18:40 as several hundred birds, probably well over a thousand, swarmed low over the field at the back of our house in St Florence. There is a large field of maize nearby where, I suspect, they are roosting.
Begs the question whether these are the same birds returning to the roost having been out foraging near and wide for the day or another passing congregation. I suspect the former as I did not see a strong passage of Swallows today at St Govan’s or back home.
