WATER BIRDS.OF THE VICINITY OF POINT PINOS, 
CALIFORNIA 
BY ROLLO HOWARD BECK 
Durtinc the period between March 1, 1903, and July 13, 1910, 
while in the service of the California Academy of Sciences as 
chief field assistant, I spent considerable time in collecting 
water birds in the general vicinage of Point Pinos—Monterey 
Bay and the adjacent ocean. The precise periods of my activ- 
ity were from September 8 to September 29, November 9 to 
- December 31, 1903; March 1 to April 27, 1904; November 2, 
1904, to February 25, 1905; February 13, 1907, to February 6, 
1908; August 12, 1909, to January 22, 1910. 
While my efforts were directed chiefly to collecting and 
preparing specimens, I availed myself of such opportunity as 
was afforded to make notes on the relative abundance and time 
of occurrénce of the birds that came under observation, and the 
results are summarized in the following pages. When deemed 
expedient to supplement my own observations, I have freely 
incorporated those of Mr. Loomis as reported in his papers on 
California water birds, published in the “Proceedings of the 
California Academy of Sciences,” 2d ser., v. 5, pp. 177-224; 
ibid., v. 6, pp. 1-30; 3d ser., Zool., v. 2, pp. 277-322; ibid., pp. 
349-363. 
With the exception of the omission of the vernacular and 
technical names of the subspecies, the nomenclature in the 
following pages conforms to the third edition of the A. O. U. 
Check-List.
