they were seen feeding in the company of American Eared Grebes, Florida Galli- 
nules and American Coots. 
While these tiny Grebes are very timid and therefore hard to observe with 
much satisfaction, they are to us the most interesting of our local water birds, 
and have afforded us a great deal of pleasure, not to mention the sets which 
repose in our cabinets.

MORE SUMMER BIRDS FOR SAN FRANCISCO COUNTY 
By MILTON S. RAY 
WITH PHOTO BY O. J. HEINEMANN 
M Y LIST of San Francisco County birds in the Condor of March, 1906 (pp. 
42-44) was based almost entirely on observations in Golden Gate Park and 
the Presidio Reservation, these localities having furnished 41 of the 44 
listed. Later field work in the Merced Lakes region, in the southeastern corner 
of the county, has yielded so many species new to the list that I have considered 
it advisable to publish the present paper. While covering, principally, the notes 
of Henry W. Carriger, J. Roy Pemberton and the writer, a number of records 
made by others have also been incorporated. Although the Farallon Islands 
form a part of our county, it was deemed, on account of their distance from the 
mainland, inadvisable to include the avifauna of those sea islands in the list. 
There is little doubt also that considered geographically the islands properly be- 
long to Marin County, being a continuation of the Point Reyes peninsula. Unless 
otherwise specified all Lake Merced notes refer to the southern lake. “Sum- 
mer”, in the title, is intended to cover the nesting period and hence must neces- 
sarily cover a large part of spring as well. Several records, including that of the 
Nighthawk and of the Hermit Thrush, have been omitted owing to the subspeeific 
rank having not been definitely determined. 
45. Aechmophorus occidental is. Western Grebe. While noted by Carriger and 
myself on Lake Merced at various dates in spring and summer we have no nesting 
record for this species. A very interesting record is A. M. Ingersoll’s, who collected a 
set of eggs, incubation advanced, on Lake Merced, June 1, 1885. 
46. Colymbus nigricollis californicus. American Eared Grebe. Noted on various 
occasions on Lake Merced. 
47. Podilymbus podiceps. Pied-billed Grebe. A common nester at Lake Merced 
through a long season. On August 6, 1911, I collected a typical nest, of decayed vegeta- 
tion, floating just off the tule-fringed lake-shore with six eggs in which incubation was 
well along. Mr. A. M. Ingersoll also has eggs of this grebe taken at Lake Merced. 
48. Gavia immer. Common Loon. Noted on Lake Merced July 4, 1911, and other 
dates. 
49. Lunda cirrhata. Tufted Puffin. Noted on San Francisco Bay near Sausalito 
in spring. 
50. Cepphus columba. Pigeon Guillemot. Found nesting on the rocky shores 
near the Golden Gate by Geo. W. Schussler, June 5, 1912. Eggs, two, fresh. (See 
Condor, xviii, p. 35.) 
51. Uria troille californica. California Murre. Noted on San Francisco Bay near 
the Golden Gate during the spring months. 
52. Larus occidentalis. Western Gull,
