Sign up now for an unforgettable, only-in-the-Bay-Area experience — the annual Return of the Terns bus tour!

Each year, a colony of endangered California Least Terns returns to nest on the tarmac of the old Alameda naval air base. The areas is off limits to the public except for one day — Return of the Terns, when you can take a biologist-led bus tour around the edges of the breeding area. This year it’s on Saturday June 15. See terns sheltering and feeding their chicks, and learn about the challenges these tiny birds face!

Register in advance, because spaces on the three bus tours will fill up quickly. Click here for the flyer with full information.
