Peregrine falcon chicks recently hatched in nests on Alcatraz Island and at a famous University of California at Berkeley landmark are part of the same family tree.
The webcams set up at the tower to watch the falcons have been popular enough that the school has held public naming contests when Annie has new chicks, including a female falcon born in 2018 that got the winning name Lawrencium in honor of an element discovered at the UC Berkeley campus.
Lidia D'Amico, the Alcatraz biologist for the park service's Golden Gate National Recreation Area, said the falcons' nest is along the western cliffs of Alcatraz in a location that is not visible from land but has a camera set up near the nest to monitor the birds' activity. Lawrencium, or"Larry" as D'Amico referred to her, was identified thanks to the band put on her leg by the Cal Falcons group of scientists and volunteers who monitor the nest at UC Berkeley, but her male mate has no such band.
An adult peregrine falcon is one of the fastest birds in the world and can dive at speeds of up to 200 mph, and the ones at Alcatraz feed most often on other birds on the island and surrounding areas. Alcatraz, during its peak breeding season, can be home to up to 10,000 or more birds, according to D'Amico.
