Birding Arrowhead Marsh 7/15/15

Yesterday I went on the Golden Gate Audubon Field trip to Arrowhead Marsh at Martin Luther King Regional Shoreline at low tide. The highlight of the morning was watching a number of Ridgway’s Rails who were walking around the mudflats relatively close to the group. Probably the best and longest views I have had of them. There were also a large number of shorebirds for so early in season including Black-necked Stilt, American Avocet, Black-bellied Plover, Spotted Sandpiper, Greater Yellowlegs , Willet, Lesser Yellowlegs, Marbled Godwit, and Least Sandpiper. The group saw a total of 39 species. Also seen were a Harbor Seal, Ray and Ground Squirrels.

Here are links to photos of the rails taken by one of the participants:

  2. Dear Mr. Steinman,
    I had wandrered in Arrow Head in Spring just to look for the rails and shore birds, there was nothing but the heat ! May be wrong time/tide & wrong spot. Would you please share/advice me the time & spot (trails, section…) for the Ridway’s rails and advice me any other close-by birding heaven . I live two hours away to the Bay.
    By the way, I appreciate your wonderful informative links to the outdoor/nature life, I have used them to establish my horizontal view. Thank you, thank you !

    • The area where we saw the Rails was opposite the parking area near the observation tower. It was low tide. Usually I have seen rails at high tide.
      The other area I have seen rails is along Pt. Isabel Regional Shoreline about a mile from the parking area (near the dog park).
      My favorite East Bay Birding areas include:
      Pt. Isabel
      Eastshore State Park in Emeryville and Berkeley
      Albany Mudflats
      Lake Merritt
      Upper San Leandro Reservoir ( East Bay Mud Lands requiring an easy to get permit)
      Martin Luther King Regional Shoreline
      Else Roemer Bird Sanctuary in Alameda

      I would encourage you to use eBird to see what birds people are seeing in each location and when they are seeing them. It is a great resource.
