Field Notes
D. A. Bell
April 10, 1990
The falcons began flying about as the whole entourage
made its way over the side of the bridge. They
were pretty quiet, but were the most defensive I
had ever seen them - making fast dives between
and three guy-wires & girders to pass right before
our faces. Also, they often landed on girders to
watch our progress. Lee Aulman pulled 4 eggs
out of the scrape. One appeared cracked, one
pitted, the other 2 OK. The press got lots of
good shots of the birds, and the Natl Geographic
group filmed us during a couple repeat takes
from different angles. Quite a circus out there.
We were interviewed and photographed quite a bit.
SF Examiner ran a front page story the next day.
The Examiners was quite accurate concerning the pesticide
and ever present problems with DDT & eggshell thinning).
The evening Ch 7 news was "too positive" about the success
(saw myself on TV!).
If the peregrines relay, we can expect first eggs
beginning April 24th. David Geiger feels the
birds will lay.
Update: May 4 - David thinks the birds began hard incubator
on a about May 1 or 2nd.
All 4 eggs hatched that were taken on April 10th). The eggs hatched Wednesday April 25,
3 hatching at the same time, one hatching later.
