Falcons return to the PG&E nest site

It’s too early to say we have a nesting pair, but recent sightings on the web camera located at the top southwest corner of 77 Beale of two amorous peregrines and sightings of them staying on the side of the building and buildings close by have gotten our hopes up of seeing a return of nesting peregrines.

The last time we had a successful breeding on that building was in 2005.  In 2006 the pair moved across the street to 201 Mission where only one eyas survived to fledge.  In 2007 the pair moved to the Bay Bridge and the male disappeared that May, followed by the female a couple of weeks later.

The falcons from the east span of the Bay Bridge had driven the first pair away.  They laid eggs in the same location on the bridge, but the hatchlings were retrieved dead from the site and the female falcon has not been seen since.

We think the male, the tiercel has a new mate and it looks good for a nesting pair, with the first egg to be laid in anywhere from one to three weeks.
