What creatures soar when the sun sets and the dark night rises over the Yolo Causeway? On Interstate 80 between Davis and Sacramento each summer evening, Mexican free-tailed bats emerge in droves to feed for the night. This September, join CapSciComm and the Yolo Basin Foundation for a family-friendly gathering to witness this natural wonder of the Sacramento region!

The evening begins with a presentation on bat natural history including the chance to see live ambassador bats up close, then the group will carpool out to the Yolo Bypass Wildlife Area to get in position and watch the “flyout” of the largest urban colony of Mexican free-tailed bats in California as they emerge in long ribbons to hunt for insects. The experience takes about two and a half hours altogether but space is limited, so be sure to grab your ticket(s) soon!
