Event description

Description

The swallows have just arrived from their long voyage from South America to their breeding grounds here in the Bay Area. Join docent Roy Sasai to view the swallows as they begin building their unique nest design. We will learn why they chose the Bay Area, their courtship rituals and unusual choice of building materials. We will hike to various spots to view their unique homes and discuss how seal level rise may risk their building material in the future. The hike is approximately 1 mile with medium hills.
