Did you know that colonies of migratory bats live under the Yolo Causeway during the summer? Join Yolo Basin Foundation for a summertime Bat Talk and Walk event and learn all about these amazing and beneficial mammals.
Following a presentation on bat natural history, the group will carpool out to the Yolo Bypass Wildlife Area for a brief tour of the wetlands and rice fields. Then, we get in position to watch the “flyout” of the largest urban colony of Mexican free-tailed bats in California. The bats emerge in long ribbons as they head out to hunt for insects for the night.
The whole experience takes about three hours. This is a family friendly event! There is a small amount of walking. Those in wheelchairs or unable to walk may view the bats by car. Please let us know if you have special needs. Bat Walk and Talk events begin late-June and run through September.
