This morning, while the train was passing along the seawall west of Fifth Street Station, I saw a flock of fifteen large shore birds straggling along, flying westward. I rode inside the steamer, but saw Larus heermanni and Larus occidentalis. July 5, 1909. Locality: Fresh water marsh on road between Mt. Eden and Alvarado, Alameda County, California. The country was very much like that about Los Banos. There were patches of tule, lots of over- flowed meadows and one or two large ponds. The following species were seen. Fulica americana. A few. I saw several young not quite able to fly, one with feathers appear- ing, and one hatched but a few hours. This last bird died under some floating grass as we approached. Podilymbus podiceps. One shot. Stilantopus mexicanus. One or two. A picked egg shell was found. Oxyechus vociferus. Fairly common. One partly feathered youngster and one in down were taken. The latter tried to hide in a hole, but was captured, while another with it made good its escape. Ardea herodias. Several. Nycticorax nycticorax. Quite a few in tules west of the Alvarado - San Jose road,
