Bolinas Lagoon, No 1, Birding in Marin Series
Location: Bolinas, CA
Trip Leader(s): Jim White and Bob Battagin
Host: Jane Medley,, 559-760-1551
Start Date: Saturday, January 21, 2017
Start Time: 8:30 AM
End Time: 3:00 PM
Description: Join us as we begin our fourth season of Birding in Marin with Jim and Bob. Last year for the first time, our group reached Jim's initial goal of spotting 200 bird species during the year! Now we invite you to help us break this 200 "ceiling" by participating in our 2017 trips to twelve of Marin's most productive birding hot spots. Bolinas Lagoon, one of Marin's Important Bird Areas (IBA), is home to many resident bird species and also serves as a wintering ground for thousands of migratory waterfowl and shorebirds. We will scan the lagoon from our meeting area and from two or three other pullouts along our route. Then we will drive 3 miles to the Duxbury Reef overlook to see what is happening on and over the ocean. The Bolinas Mesa oxidation ponds often provide another good place to look for birds. We will then take a lunch break in downtown Bolinas. After lunch with the lower tide we will look for shorebirds near the Pine Gulch Creek delta. Directions: Meet at 8:30 AM on Highway 1 at the Stinson/Bolinas Primary School, which is 1.5 miles north of the central Stinson Beach stop sign. Heavy rain cancels.
