On Saturday, May 20, Annie sits on a loudspeaker on the roof of Evans Hall, seemingly calling out the start of Fledge Watch, an annual springtime event when her newest offspring learn to fly off the Campanile. (Photo by Bridget Ahern

Annie is now about 10 years old and headed into her eighth breeding season. She has hatched 18 chicks on the Campanile since arriving on campus in late 2016. (Photo by Bridget Ahern
On Tuesday at sunset, Zephyr peers down from an opening in the Campanile’s upper balustrade, through its fleur-de-lis ornamentation, but is not ready to fly. Neither are his sisters, Luna and Rosa. (Photo by John Davis
On Thursday, with the flap of her wings, mother Annie (above encourages Zephyr (right and Luna (left to jump off the west side of the tower and to try and fly. They don’t budge. (Photo by John Davis
Lou also gets ready to help his offspring, positioning himself on a corner of the Campanile as Luna (left and Zephyr (right look north from the tower. (Photo by John Davis
On Thursday evening, May 25, Luna looks out at the world from the same balustrade, but decides to stay put. (Photo by Bridget Ahern
Zephyr still is not ready. None of the young birds has yet flown. (Photo by Bridget Ahern

On Friday, May 26, Zephyr is the first to try flying. He leaves the Campanile at 3:45 a.m. and lands on the oldest building on campus, South Hall, which was completed in 1873. This photo was taken at 10:43 a.m., when he was continuing to test his skills there. (Photo by Bridget Ahern
“I did it!” Could that be what Zephyr’s expressing? (Photo by Bridget Ahern
Rosa takes her first flight around 7:30 a.m. on Friday, May 26, about four hours after her brother Zephyr did. (Photo by Bridget Ahern
Later that morning, Lou (left stays close to Rosa. (Photo by Bridget Ahern
In the evening, Rosa attempts a tricky landing on the Campanile. (Photo by Bridget Ahern
It’s a vertical challenge, but Rosa eventually nails it. (Photo by Bridget Ahern
Zephyr keeps practicing that Friday. Here, he gets his talons ready for another landing. (Photo by Bridget Ahern
Annie brings food to Zephyr on South Hall. She subsequently places the food into his mouth. (Photo by Bridget Ahern
Zephyr chooses to spend the rest of Friday in a tree. He’s too tired to fly back to the nest on the Campanile. (Photo by Bridget Ahern
Looking confident, Luna, the largest of the two female juveniles, soars through the skies on Friday evening. This photo is of her first flight. (Photo by Bridget Ahern
As she lands, Luna gives us a look at her beautiful wings. (Photo by Bridget Ahern
The next morning, on Saturday, the three falcon siblings spend some time together on the Bancroft Library. (Photo by Bridget Ahern
Then Zephyr decides he’ll fly over to Evans Hall. (Photo by Bridget Ahern
Luna heads over to Doe Library. (Photo by Bridget Ahern
Her sister Rosa (right joins her. (Photo by Bridget Ahern
A sisterly exchange ensues. (Photo by Bridget Ahern
On Sunday afternoon, May 28, Luna does some “loafing” on the Bancroft Library. (Photo by Bridget Ahern
An hour later, she’s ready for her next flight. (Photo by Bridget Ahern
Luna chooses to spend time in a tree near the Bancroft Library with Zephyr (left. (Photo by Bridget Ahern
Later on Sunday afternoon, Lou delivers a meal to Rosa on Wheeler Hall. (Photo by Bridget Ahern
As Sunday evening arrives, Luna is back on the Bancroft Library. (Photo by Bridget Ahern
