I was observing on site at 1201 yesterday afternoon. By 4 pm, one egg was
clearly showing a large pip mark. Saw pip marks on second egg a short time
later.

First egg eventually hatched while out of sight under the adult. First
"light of day" where I could see it at 1827. Could hear both chicks calling
from inside the eggs through their pip holes.

Noticed that the hatch was inadvertently assisted by the adult as it kept
moving around and settling in on the eggs repeatedly. Far more often than
normal. She certainly applied pressure on the delicate, cracking shells.
Peregrines get really restless at this stage as they clearly know the
chicks are hatching from their vocalizations.

Ed Deal will band them in about 3 weeks.

In the meantime, enjoy.
