April 6, 1988
We did not get back to Garberville until @
21:00, as the Peregrine Fund guys wanted to go
as slowly & smoothly as possible. Did not
get back to Berkeley until 1:30 a.m.
April 7, 1988
Matt Nixon called to say that the 3 eggs indeed
appear to be OK, with no overt eggshell
thinning. The pits were thought to be normal.
Now, only time will tell if they hatch.
All in all then, there were no eggs in
the scrape on March 27, 1988, when I
climbed in to inspect it. If the falcon laid
her first egg the next day, which she might
have, since she was so lethargic, that
would mean, Monday, March 28 was first
egg. Every 52 hours later they lay, so she
probably completed her clutch on Friday,
April 1. This would mean that the eggs
had 5 days of incubation when we took them
[marginally]. It takes 32 days for the eggs to
hatch, so hatching should be around May 2.
