FULMARS AND SHEARWATERS 
until started on their journey by a rising wind. None of our Pacific 
coast sea birds adhere so closely to established fly lines as the puf¬ 
fins. Mr. Anthony tells us {Auk, xiii. 223-228) that “even when fly¬ 
ing fifty miles or more from land the first flock that passes will, with 
almost absolute certainty, mark the line which the next will follow, 
even though they be an hour behind.” 
Mr. Anthony calls attention to the habit common to different spe¬ 
cies of shearwaters of flying in large circles or an advancing series 
of loops when quartering the sea for small fish, — a flock seen along 
shore going in the opposite direction from one farther out to sea. 
96. Pufifinus griseus ( Gmel. ). Dark-bodied Shearwater. 
Entire plumage sooty gray except for white under wing coverts, which 
are mottled with gray at tips ; bill and feet dusky or black. Wing: 
11.15-12.00, bill 1.55-1.70, depth of bill at base .45-55, tarsus 2.12-2.35. 
Distribution. — South Pacific, north along the coast of California, and 
reported in great numbers from Queen Charlotte Islands, B. C. 
One of the most important results of the valuable work done by 
Mr. Loomis on the water birds off Monterey is the light thrown on 
the northward migration of birds from the south temperate zone. 
The dark-bodied shearwater affords conclusive evidence on the sub¬ 
ject. The shearwaters taken at Monterey in May were in worn, 
moulting plumage, common with birds just after the breeding season; 
while their sexual organs showed none of the functional develop¬ 
ment of birds about to breed. The migratory movements of these 
birds increased from May until September, when there was an 
abrupt decrease in their numbers, only stragglers being seen after¬ 
wards. Not only were the September and October birds in fresh 
plumage, but those secured had their sexual organs enlarged as in 
birds in the flush of the breeding season. As the shearwaters are 
known to breed from October to March on oceanic islands in the 
south temperate zone, the case seems to be a simple one. 
96.2. Puffinus bulleri Salvin. New Zealand Shearwater. 
Adults: mantle gray, in striking contrast to black on head, tail, and 
lesser wing coverts ; greater coverts gray, tipped with white ; outer pri¬ 
maries black, with two thirds of inner webs white ; cheeks mottled grayish 
white; lower parts and under wing coverts white. Length: 16.50, wing 
11.30, tail 5.20, bill 2.60. 
Distribution. — New Zealand. One record from Point Pinos, California. 
Mr. Loomis secured a specimen of Puffinus bulleri about six miles 
west of Point Pinos, on November 6, 1896. As this was the fourth 
of the species known to science, and the others had come from New 
Zealand seas, the record is of great interest, and as pointed out 
suggests that persistent observation along the Pacific coast may add 
largely to the list of pelagic wanderers from the southern seas.
