These are possibly not, local birds and may be migrating as a flock from elsewhere?
From my balcony: 15 on Wednesday, 4 on Friday, 2 today. Same weather as Jan's, less than an hour's drive to the southeast. (On Thursday I was away, so no count).This is the first recorded case of Swifts breeding in a tree in Holland.
The day before yesterday I have still seen a few Swifts around here in the eastern part of the Netherlands, like most days; yesterday was very hot, followed by thunder. Now the sky is empty (well, full of clouds and there is some sunshine), but of course all August Swifts are considered "late".

That's exactly what I thought, despite it being a tight feeding group - the previous peak numbers being around the 20-30 mark. Back down to the usual half dozen to dozen each day since then.
Only 1 this morning...
30 or so in the skies above my house today. Taking advantage of easy pickings from flying ants. It would have been a shame if they had missed out on that
None yesterday evening or this morning!
