Megan Isadore, head of the River Otter Ecology Project, brings the latest on these lithe carnivores' Bay Area comeback. How are populations changing? How do otters live and eat through the seasons? Learn how fascinating research techniques and citizen science are helping us understand elusive, secretive mammals that slide into the water and disappear.

Co-sponsored by the California Center for Natural History, Friends of Five Creeks, and Bay Nature Magazine -- read their story on river otters here.

Bay Currents talks are sponsored by Friends of Five Creeks and happen on the second or third Tuesday of the month at St. Alban's Parish Hall, 1501 Washington (at Curtis, one block north of Solano). Refreshments 7 PM, talks 7:30 PM. Free, but seating is limited. Full spring schedule here.
