Bat Talk & Walk

Join local bat expert and researcher Greg Falxa for a talk about the extraordinary life of bats and the important role they play in our local ecosystem. Following the talk, Greg will lead a bat walk at sunset. During the walk, he uses a bat detector to listen in on the bat sounds as he discusses more about the bats and their feeding habits, habitat needs, and problems facing bats worldwide and locally. Learn the basic facts and dispel some of the common myths about bats by attending Stream Team’s annual June bat lecture and walk.

Over the past 50 years bat populations have been declining. It is believed that the loss of roosting habitat needed for maternity colonies is largely responsible for this decline. Woodard Bay, located about 15 minutes northeast of Olympia in Henderson Inlet, hosts the largest known maternal colony in Washington State. Approximately 3,000 pregnant females utilize the historical logging railroad trestle as a maternity roost. The trestle provides a safe warm place to birth and raise young. Since the Woodard Bay roosting area is on the salt water it doesn’t provide a food or water supply, the bats make the 8 mile nightly commute to drink and feed at Capitol Lake in downtown Olympia. Typically bats emerge from their roosting sites around sunset and fly off to first drink then to feed during the night. On a typical summer night at Capitol Lake, these bats may be seen feeding as they skim low over the lakes surface. Another large maternity colony resides at the Evergreen State College farm house. Many of the bats seen at Capital Lake are Yuma (Yuma myotis) and little brown bats (Myotis lucifugus).
