Not much to add. Whilst in garden still have up to 5 swifts screaming round. One swift is incubating the eggs most of the time. Occasionally they seem to have the urge to fly together. A glance at the bedroom nest showed 3 eggs. Swifts have either2 or 3 eggs. Short clip showing the evidence.

Will be away for a few days. Should be back in time for hatching
