Join San Francisco Bay Bird Observatory biologists at Eden Landing Ecological Reserve to view one of only six San Francisco Bay breeding colonies of endangered California least terns.
The group at the free event will look for adults incubating nests, young downy chicks being fed by their parents, older feathered chicks running around the colony, and fledglings learning to fly.
California least terns (Sternula antillarum browni) are endangered ground-nesting seabirds, and SFBBO biologists and volunteers actively monitor the colony, which is breeding on enhanced former salt production ponds at the California Department of Fish and Wildlife reserve in Hayward.
SFBBO will provide some spotting scopes for attendees to use, but urges participants to please bring spotting scopes if they have their own.
In accordance with SFBBO's COVID-19 safety protocols, the organization is asking that participants wear a well-fitting mask at the event and fill out an online health self-assessment form the day before the event.
