Field Notes D.A. Bell May 6, 1990 Update on Golden Gate Peregrine Eryie: Yesterday (may 5), David Gregorie and helpers were at the eyrie in the afternoon. At 16:30 the inculating ♂ came off the nest and received a meadowlark (?) from the ♀. The ♂ went to the eyrie to incubate. ♀ flew to cliff, ate lark, disappeared. 10 minutes later she reappeared chasing a bird-tailed pigeon right past the eyrie, but did not get it. She flew back to the bridge, then soon was off at a gull. She harassed the gull, then chased a small passerine, catching it, she then returned to the bridge and dos cached her kill. Soon she was off at another gull, this time she pounded it into the water, (defensive screaming). Finally, at about 17:15 she went back to the eyrie to relieve the ♂ and continue incubating. Today, May 6, while talking to David over the phone he got another call saying that one of the peregrine eggs had hatched! This hatched at about 11:15 am -> approx. 37 days after "hard" incubation had begun! WOW...
