On Monday the 25th we had one Swift circling high above the house but the two young that had been looking out of our middle box the previous week were no longer there, so I assume they had fledged. Since then, despite keeping a keen eye on things, we have had no further sightings and no more droppings have appeared, so we assume they have all departed, alas!

I see from my diary that they fledged on 1st August last year and we had no further sightings so it would seem to fit. (SB)
