Several friends were watching the falconcam yesterday, March 9, as Hope laid her second egg at 11:21am. I heard the news immediately even though I couldn't touch my cellphone (I was driving).
Experienced egg watchers knew she was laying an egg because she stood above the scrape for a while with her tail down, then raised it as shown above. This posture is subtle in the still photo but obvious on streaming video.
It was cold yesterday -- only 31 degrees F -- so the peregrines stayed on the eggs to keep them from freezing.
When Hope left the nest for a break ...
... Terzo arrived to shelter the eggs.
Though Hope and Terzo have been "on the eggs" they won't begin true incubation until she's laid her next-to-last egg. Click here to read about the peregrines' incubation strategy.
Hope typically lays four eggs, each two and a half days apart, so you'll get two more chances to watch for that tail action. However, her next egg will probably be laid in the middle of the night.
