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.
