The Yolo Bypass Wildlife Area (specifically the I-80 Causeway Bridge) is home to one of the largest Mexican free-tailed bat (Tadarida brasiliensis) colonies in California. An estimated 250,000 individuals emerge each evening to forage. This is a taste of the emergence that lasts for over 40 minutes with thousands of bats flying out in a column every minute. It is quite a spectacle. that was visible from the main entrance to the Wildlife Area auto tour route. Check with the wildlife area for up to date status on the colony.

The UC Davis Museum of Wildlife and Fish Biology survey team has embarked on a bat inventory on Putah Creek, California as part of our long-term monitoring program now in its 16th year. We found a significant roost of bats under one of the overpasses crossing the creek recently and I was able to get photos of these Pallid Bats (a large species species (several Brazilian free-tailed bats are nestled in on the lower left). Our surveys include visual surveys, sonobat detectors and mist netting. It is really exciting to explore a new guild of critters on the creek.
