Among the mammals of Caltech, they’re arguably the happiest and freest. While Homo sapiens are burdened with homework and deadlines, and coyotes stick to moonlit hours to avoid the crowd, the fox squirrels roam wherever their paws take them. Stroll across campus and you’re guaranteed to spot one: foraging randomly in the grass (no, they don’t remember where they bury their nuts), lounging on a branch, or chasing a friend in spirals around tree trunks, like a dazzling ribbon in the hand of a gymnast. Even if you don’t see one, just look up: the treetops are decorated with their nests, ready for year-round breeding.
Pasadena alone has a surprising number of foreign bird species. Look closely and you can spot these feathered visitors daily at Caltech—including some that are endangered. This week’s wildlife column is about these special bird immigrants.
Spring at Caltech is a season of rapid transformation. Step away for just a few days, and you’ll return to a campus bursting with changes: the once-bare branches are now decorated with colorful flowers. The drastic changes aren’t limited to flora – migrating wildlife also contributes to the seasonal dynamics.
Woodpeckers are perhaps the most overlooked yet ever-present wildlife species on campus. Like the ubiquitous fox squirrels (a topic for another day), they are a daily sight if you know where to look.
