We are Annie and Lou, the Peregrine Falcons living on the Campanile at UC Berkeley! Check us out at calfalcons.berkeley.edu
We had an unknown female visiting the tower this afternoon. Hopefully we'll start to see more exploration of the Campanile soon!

This is the first year since Cal Falcons started up that we haven't been celebrating by watching Annie stuff bloody hunks of pigeon meat into the ravenous gullets of a pile of fluffy falcon chicks. But even though we're missing our beloved Annie this year, we wanted to honor all the moms out there.

UC Berkeley researchers just published a paper about conservation funding featuring Annie as a case study!
They found that messaging can have a dramatic effect on donor sentiment, and that Annie's story led to positive associations.

We just had a new falcon visiting the Campanile for 15 minutes or so. Fingers crossed it will continue to hang out and get to know the area!
Based on head, bill shape, and skin and feather coloration, it appears to be a new bird.

As avian flu continues to kill birds worldwide, @calfalcons.bsky.social says the disease "is hitting peregrines very hard right now,” and is likely why UC Berkeley’s resident falcon, Annie, and her mate, Archie, haven’t been seen on campus in nearly two months. news.berkeley.edu/2025/02/24/u...

Hi everyone,
All three cameras are back in operation, including the upgraded South/West camera.
We also wanted to take a moment to talk about how quiet things have been on this site and also at the Campanile. Neither Annie nor Archie has been seen at the Campanile since early January.

Winter season affords us an opportunity to perform maintenance and upgrades. This year, we upgraded our south/west camera! It should provide sharper images and fix some focus issues that we have had.
Huge thank you to Peter Sharpe at the Institute for Wildlife Studies for lending his expertise!

We received the final pathology report from UC Davis. Nox died due to a bacterial infection and pneumonia.
We wanted to send our heartfelt thank you to all the veterinarians and wildlife care volunteers that assisted along Nox's journey. We'll miss him.

Thread: Annie has never successfully hatched all four eggs in any year we've monitored her. There's always been an egg that didn't make it. Nox was the exception to that: a tiny little bundle of fluff that hatched out of his egg as hundreds of people watched live on BAMPFA's big screen

We are deeply saddened to receive the news from UC Davis that Nox passed away last night. They will be performing a post-mortem to determine the cause of death, which is still unknown.
We will be posting an in memoriam a little later today when we have time to honor Nox properly.

Hi all,
Nox is currently under care for an unknown ailment. Veterinarians are working hard to determine what is affecting him and how to best treat him. Please be patient as we wait for more details.

Nox ended up on the ground this afternoon and has been recovered by Bay Raptor Rescue. There do not appear to be any major injuries in an initial examination. We’re not sure what happened, but he will be getting a healthy portion of quail tonight and a thorough examination tomorrow.

Nox has completed his rehabilitation and has been released (with a fancy new backpack!). With his new GPS tag, we'll be able to peak into one of the big mystery of: where juvenile birds go after they leave their parents' territories.

A drone was observed flying above the Campanile today. Annie remained in the nest incubating the eggs, but Archie flew out to investigate and defend the site. Thankfully, Archie returned unharmed. (Image credit: Bridget Ahern, moon_rabbit_rising on Instagram)
