Harbor Porpoises Return to San Francisco Bay

7:00 - 8:30


Merced General Floor Area

155 Winston Drive

Join Bill Keener, co-founder of Golden Gate Cetacean Research, for a presentation on the return of the harbor porpoises. Harbor porpoises (Phocoena phocoena) had been missing from San Francisco Bay since World War II, but they've returned in increasing numbers in recent years. Keener will discuss the disappearance of porpoises, the mystery of their unexpected return, and how you can help by reporting your porpoise sightings.
