Cogswell 1948 Yavia immer Dec. 18 - Tomales Bay, Marin Co., Calif. - close views of at least 4 different birds of this species, one in first winter plumage (i.e., light edgings to back feathers) along the E shore of bay was so tame we could walk up & down on shore only 200 ft. or so from him without disturbing him. The very large heavy bill of this species was quite evident on this bird, and at least 2 other loons well out in bay at the same time were distinctly larger than cormorants near them [See Yavia stellata for general comments re loon population here today]. 1949 Sep. 14 - Moss Beach to Pedro Pt., San Mateo Co., Calif. at least 15 or 20 of the 25-30 loons seen on the ocean along here today were of this species, judging from comparative size and the very heavy bills (a few still showed traces of breeding plumage pattern on the back). This seems an early date for so many individuals. Dec. 25 "Crystal Beach", Santa Monica - Ocean Park, L.A. Co., Calif. - 1 seen on ocean just offshore Dec. 28 - Morro Bay, San Luis Obispo Co., Calif. - 4 seen in the bay near its mouth; 1 of them (swung only suspect) seen swimming under water near the sandy shore just W of Morro Harbor. It was chasing a fish which eventually eluded it despite twists & turns by the loon in water so shallow its back was out.
