Peregrine Falcon Egg Hatches: Video; Party Planned For Tuesday
A crowdfunding campaign in 2019 led to the installation of two webcams that live-stream the nesting area and balcony to the public 24/7.
BERKELEY, CA — The first of four eggs laid this year by famed U.C. Berkeley falcon Annie and her new mate Lou was expected to hatch sometime between 8 p.m. Monday and 5 a.m. Tuesday in a nest atop Campanile tower, where Annie has made her home for several years.
But the tiny falcon was anxious to enter the world, hatching Monday afternoon.
Cal Falcons, the group of scientists that monitors the falcons and posts regular photos, commentary and memes about them onto social media, posted video of the chick's debut on YouTube.
After Annie and her late mate Grinnell made their home in the Campanile in 2017, a crowdfunding campaign in 2019 led to the installation of two webcams that live-stream the nesting area and balcony to the public 24/7.
On Tuesday, the UC Berkeley Art Museum and Pacific Film Archive (BAMPFA) is hosting a Hatch Day celebration where the falcon cam will be broadcast live from 9 a.m. to 5 p.m. for free on an outdoor screen as, possibly, more eggs hatch. A team of falcon experts will also share information and insights about the birds during the event.
Cal Falcons wrote in an update Friday that signs of eggs starting to hatch may happen as early as Saturday evening.
"Inside the eggs, the chicks will be working on piercing internal membranes and then cutting a tiny crack in the shell (called a 'pip') that will let the chick breathe air for the first time," the group wrote.
The chicks' mother Annie has had an eventful past year.
According to UC Berkeley, in March 2022, Annie's longtime partner Grinnell was found dead on campus. Eggs Annie laid before Grinnell's death would not have hatched except for the arrival of a new falcon, eventually named Alden, that helped incubate the eggs.
Two eventually hatched that were named Grinnell Jr. and Lindsay, named after Walnut Creek's Lindsay Wildlife Experience that took in Grinnell for rehabilitation after he was found injured in a 2021 tussle with rival falcons at the Berkeley Tennis Club.
Lindsay then was found dead in August from an apparent attack by a red-shouldered hawk. Annie's new mate Alden then left in November and was not seen again by the Cal Falcons group.
That allowed the latest mate to swoop in, and a naming contest held by the school this February left him with the name Lou, a reference to Louise Kellogg, a UC Berkeley alumna who was the partner of Annie's namesake, Annie Alexander.
