This is a hoary bat call that was detected at the Los Angeles Zoo using a bat echolocation monitoring device. Hoary bats are a migratory bat species that travel from Canada to south America every fall. They only roost in foliage so they are sensitive to urbanization and are great indicators of ecosystem health. The long term monitoring device is in place to collect long term data on Los Angeles bats and to educate zoo visitors and the public about local bats and the important roles they play in ecosystems. The project is a collaboration between the Los Angeles Zoo and the United States Forest Service. All species are identified by using Sonobat bat call analysis software.
