Tucked away on the far corner of the estuary you will see on any given chilly, foggy day Marbled Godwits and Willets huddled close together. Marbled Godwits are shorebirds with long, pink-based bills and cinnamon brown plumage. They resemble Long-billed Curlews except that the bill turns slightly upward, not downward.
Willets are tall, plain gray shorebirds with a medium-length straight bill that probes the sand for crabs. The Willet is more common in winter. But they will occasionally show up on the central coast of California on a cool, foggy day as illustrated in the photos below. Willets spook easily. If intruded upon they will fly quickly away and become the loudest and showiest of all shorebirds rousing other dozing birds as they sound the intruder alarm.
