breeding season in the South Temperate Zone only stragglers 
are present. During the latter part of April they return in 
force, becoming very abundant in May and irregularly so in 
summer and early fall. In 1907, a gathering of fully twenty 
thousand was seen on November 4, a late date for such large 
numbers. 
47. Puffinus tenuirostris. SLENDER-BILLED SHEARWATER.— 
Seemingly they are of regular occurrence in this vicinity in the 
return-migration to the Southern Hemisphere. In some years, 
however, they appear to be more numerous than in others, 
notably in December, 1895, as observed by Mr. Joseph Mail- 
liard. December 2, 1907, was the day of greatest numbers in 
my experience, twenty-nine specimens being secured and oth- 
ers seen in a gathering of over two thousand Black-vented 
Shearwaters. The earliest occurrence coming within my 
observation is October 14, 1907, and the latest, January 30, 
1908, a specimen being taken in each instance. 
48. Puffinus carneipes. FLESH-FOOTED SHEARWATER.—In all, 
ten specimens of this shearwater have been taken by me in 
the vicinity of Point Pinos, adding another species to the list 
of birds of the American side of the Pacific. The specimens 
were obtained under the following dates: November 23, 1903; 
November 24, 1904; February 27, April 29, June 25, August 
27, September 2, and November 4, 1907. 
49. Puffinus bulleri. BULLER’s SHEARWATER.—The A. O. U. 
Check-List has rechristened this bird the “New Zealand Shear- 
water,” and has defined its range as “New Zealand; north 
casually to California.” Ten specimens have been taken by 
me in fall off Point Pinos, double the number recorded from 
New Zealand seas in Godman’s “Monograph of the Petrels.” 
The first recorded specimen from the Northern Hemisphere 
was taken by Mr. Loomis, and noted by him in the fourth of 
his California water bird papers. 
50. Priofinus cinereus. BLACK-TAILED SHEARWATER.—The 
only record we have for this vicinity is the time-honored one 
of Lawrence, based on Pike’s specimen, which is now housed 
in the American Museum of Natural History. 
51. Oceanodroma furcata. FoRK-TAILED PETREL.—In its 
migrations this petrel probably passes Point Pinos well off- 
shore. Sometimes it comes within the shelter of the land. 
Such was the case in June, 1895, when it was plentiful in the
