Apus apus (Common swift) - Diary 2026

My notes on the activity of swifts at my house in 2026...


See the main page for notes, photos, and diaries for other years.

You can view live video here from some of the nestboxes (not guaranteed always online, but I try to keep it running).
Not yet online for 2026 season as the birds haven't arrived.
Here is a page with some explanation of how I do the video.

Predicted dates above based on the average for previous nests with camera: last egg to hatching 19 days; hatching to first fledging 42 days.

2026-May-2 This morning, around 07:30, I heard then saw two swifts flying nearby. I've continued seeing and hearing them later in the day. They are likely swifts which nested here last year, and are probably going into a nest-place, but I don't yet know which (not either of the ones with cameras). At present, there are starlings with young in #sb4, and sparrows in #b2 - both these nest-places were used by swifts in 2025.

2026-May-1 Getting ready for a new season. No swifts sighted yet.

The two video cameras are not yet online for the 2026 season (link to live video above).
