SUMMER TRIP TO NORTHERN SANTA BARBARA ISLANDS 
173 
eggs on June 6 of that year, I believe this is the first record of a breeding colony 
of these birds south of the Farallon Islands. 
Western Gull ( Lams occidentalis) . Breeding commonly on all out-lying 
rocks and islets. Fresh eggs were found as late as June 18. 
Heermann Gull ( Lams heermannt ) . Common, feeding along the beaches. 
Royal Tern ( Sterna maxima) . Several immature birds seen and one taken at 
the west end of the island June 17. Altho this bird has been reported breeding on 
San Miguel, I am satisfied that none were nesting there this year. We went over 
the island thoroly and found no evidence of their breeding and only observed the 
birds in the one instance as noted above. 
Farallon Cormorant ( Phalacrocorax a. albociliatus ) . There was quite a large 
colony of these birds breeding on Prince Island. Many of the nests were placed in 
the cactus patches on the eastern side of the island. On June 15 we found nearly 
full-grown young, and eggs in various stages of incubation. 
Brandt Cormorant (Phalacrocorax 'penicillatus) . The most abundant of the 
cormorants on Prince Island, breeding in several large rookeries. Nests contained 
from fresh eggs to nearly grown young on June 15. Owing to the ravages of the 
gulls some of these birds must lay several sets of eggs before they succede in raising 
young. In one colony of about a hundred pairs which we past on the morning of 
June 15, all of the nests contained eggs. On our return in the afternoon there 
were not a dozen eggs in the whole colony. The cormorants had been frightened 
from the nests by our presence and the gulls had done the rest. I collected one 
set of 6 eggs of this species. 
Baird Cormorant ( Phalacrocorax resplendens) . Breeding commonly on the 
cliffs everywhere. Some young were noted, but most of the nests contained eggs. 
Fresh eggs were found as late as June 19. 
California Brown Pelican ( Pelecanus calif ornicus) . Five nests containing 
young were found on Prince Island, June 15. -i ' m 
White-winged Scoter ( Oidemia deglandi ) ; Surf Scoter ( Oidemia pcrspicillata ) . 
Immature birds of both these scoters were common around all the islands visited. 
They are plentiful along our southern California coast thruout the entire summer. 
Western Willet ( Catoptr op horns s. inornatus ) . Flock of 10 or 12 birds seen at 
the west end of the island June 17. 
Wandering Tattler ( Heteractitis in ca nils) . One or two seen daily during our 
entire stay. 
Black Turnstone ( Arenaria melanocephalai) . Male taken June 21. 
Black Oystercatcher ( Haematopas bachmani) . Breeding commonly on 
detacht rocks and islets. Apparently nests nearly a month later in this locality 
than it does on the San Luis Obispo coast. (See Willett, Condor XI, Nov. 1909, 
186-187.) The earliest nesting record I have from San Miguel is that of young 
about two weeks old taken June 23. Five sets of eggs were taken as follows: Set 
of 2, incubation about one week, taken by Owen, June 9. Set of 2, fresh, taken 
by Howard, June 10. Set of 3, fresh, by Willett, June 17; and 3 slightly incubated, 
and two fresh, taken by Appleton and Willett, June 18. 
The following birds were observed at sea: 
Least Tern ( Sterna until lamin ') . Feeding commonly at sea on June 24 about 
18 miles out from the southern Ventura County coast. These birds were probably 
from a colony which J. S. Appleton has noted breeding near Hueneme. 
Pink-footed Shearwater ( Puffinus creatopus ) . First noted off Santa Cruz 
and Santa Rosa Islands June 7. By June 24 it had increast in numbers until it was 
quite plentiful.
