Although there are no running rivers in Tucson anymore, we still have many bridges that span the dry riverbeds and the large washes that feed them. The expansion joints under these bridges provide an ideal habitat for several bat species that live here during the warmer months. Every evening, at sunset, thousands of bats emerge from under these bridges to eat their fill of insects throughout the night. Below are some images of one such emergence from the Broadway bridge over the Pantano wash.
