Alameda mud flats. The birds are beginning their southern migration. Lots of curlews, western sandpipers, and a few dowitchers and marbled godwits. However, very low tide, and had difficulty identifying birds because they were so far away. Am going to look into getting a spotting scope.
Saw a lot of birders on one of the platforms extending into the mud flats at the drainage ditch/creek. Almost all of them had scopes, which is unusual for a typical bird walk. On the way back, still a couple of people there, and one of them asked me if I had seen the red necked stint. I said another birder had played the call of the stint. Very rare sighting, as usually the bird is in Asia, and occasionally will get to Alaska, but very rare to be in California. I never saw it, however. It looks veery much like a western sandpiper except for a reddish neck, of which there were a lot. I wouldn't have been able to pick him out.
