Falcon fledge watch in action!
By Ilana DeBare
High drama is happening amidst San Francisco’s high rises as four Peregrine Falcon fledglings learn to fly – and as intrepid human volunteers help them recover from potentially-deadly missteps.
The four chicks – two male, two female — hatched at the end of March in a nest on the 33rd floor of the downtown PG&E building. By the beginning of May, they had gained their flight feathers and were ready to take wing.
But first flights – never easy anywhere – are particularly dangerous in a downtown of concrete canyons and glass walls.
“San Francisco is an incredibly difficult place for babies to fledge,” said Mary Malec, one of about 20 volunteers who are monitoring the falcons from street level and from a donated suite in a nearby office building with a view of the nest. “There are so many buildings to run into. Some are glass, which birds can’t see. It’s easy for them to end up on the ground, where they can run into trucks and buses and all sorts of hazards.”

Within the past week, both of the young male falcons have had close calls:
Sutro’s Tower
Sutro, one of the males, flew to a nearby building last Thursday. When he tried to return to the nest site, he missed and tried to land on another building. But it had a smooth façade and his talons couldn’t find a grip: He dropped off and fell, flew, tried to land again, and ended up on an architectural pillar only 15 feet above the street.
“Baby Peregrines fly well – it’s landing that they don’t know how to do yet,” Malec commented.
Sutro would have had a tough time regaining the 33rd floor or comparable heights – where the parent falcons continue feeding the young ones — from such a low launch spot. So the fledge watch crew called Glenn Stewart, director of the Santa Cruz Predatory Bird Research Group and a kind of fairy godfather to young Bay Area raptors. At 9:30 p.m., the volunteers managed to find a ladder and Glenn climbed the pillar, trapped Sutro in a rescue box, took him to a vet for an overnight check, and returned him to the PG&E nest ledge.
The Perils of Perry
Perry, the other male eyas (young falcon), had flown successfully a couple of times last week.…
