This morning at 11:50, Astrid laid her 4th and likely final egg. Interestingly, only 20 minutes before, she had returned to the nest box to relieve Ares from incubating. Ares didn’t seem to want to leave (it is after all, a miserable kind of day weather-wise), but Astrid insisted and took over sitting on what was then, the 3 eggs. We expected egg # 4 to come later in the day, so we were surprised when at one point she shifted and revealed it. The new egg was easy to pick out since it’s a brighter shade of brown than the others (all freshly laid eggs are). Though it’s conceivably possible that Astrid will produce a 5th egg, we think it’s unlikely, but just the same, we’ll be on the look out for it this coming Friday.
