After Lux — one of the peregrine falcons born on the Campanile — died last year after striking a window of Evans Hall, the campus community was heartbroken. But Carla Cicero, the staff curator of birds at UC Berkeley's Museum of Vertebrate Zoology, has given the peregrine a new purpose. Lux is now one of 750,000 specimens — birds, amphibians, reptiles and mammals — at the museum used for research at Berkeley and across the world. Lux is the 4,287th specimen that Carla has prepped for the museum in the past 30 years. Although the museum is closed to the public, for one day a year — Cal Day, in April — people are invited in to see special displays.See photos and read the story on Berkeley News.
