Field Note. Doug Bell 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.
