44. Ardea herodias. Three or four in shallow water of bay at low tide. I noted one secure a fish, getting its head quite close to the water before striking. Nycticorax nycticorax. Three or four feeding on marsh with curlew. Noted four or five flying southeast over marsh. Bistothorus palustris. I noted one on blade of marsh grass, singing loudly. Regulus phoeniceus. Several in marsh, males singing and with very bright wing patches. I searched in one place for a nest, but found none, although two or three pairs of birds were about. When the tide began to fall, the narrow strips of mud became occupied by every hungry shore birds as fast as they were exposed. The birds seem to come out of nowhere, just as when the tide rises they seem to melt away. 3733 Pelidna alpina & Alameda, Cal., Apr. 29, 1908; C. D.S.
