Gaining insight into what the nest cup on Nest 1A contains has been a tricky task but some of the obstructions have been moved and partial views are possible. The first time frame by frame analysis of shuffles revealed three eggs was this morning.

So when was egg 3 laid? Best guess is late on wet and windy 16 April morning. YA hadn’t incubated but in wet weather females tend to do all the work. Sometimes we could see the top of two eggs lying side by side when she shuffled the eggs but on occasion none were visible in the deep cup. At 13.31 when she stood there was one egg under her tail and not by her brood patch. But only one egg was in view in that cosy place so we were still unclear if the rear egg was newly laid.
