At 9.47am the first egg was laid. Not only was this amazing to watch, but it instantly revealed that our partial albino bird is a male! He stayed with his mate throughout, just out of shot when the egg was laid, but returned to her very soon afterwards. The effort required to lay the egg was quite protracted with bouts of hard pushing and lengthy resting periods. After the egg was laid the female looked exhausted, but within ten minutes after some affectionate mutual preening they mated on the nest. The weather is hot and sunny,  perfect conditions for the female to build up strength again to recover and prepare for the next egg which will probably be laid on 30th May. Normally Swifts lay two or three eggs.
