North Bay Heron & Egret Project

Join our volunteer field observers and track heron and egret nesting activity throughout the five northern San Francisco Bay area counties. Your work will provide vital information about nesting Great Blue Herons, Great Egrets, Snowy Egrets, Black-crowned Night-Herons and other species, to advance the important work of scientists, planners and conservationists.

Shorebird & Waterbird Monitoring on Tomales Bay


Each year, volunteer field observers assist ACR scientists on studies of shorebirds and waterbirds in Tomales Bay. Join the team, and you’ll help collect data on these birds from boats and from the shores of beautiful Tomales Bay. Volunteers should have excellent birding skills and be able to identify birds in flight and from a distance.
