Tufted Puffin (14) Willett, Condor, x1, 1910, p. 170. 
Common resident about the northern islands, occurring farther south in win- 
ter. C. B. Linton and G. Willett (70) each saw a bird near San Nicolas in May, 
1910, and on June 23,1911. The latter date would indicate that the birds possi- 
bly breed in the vicinity, but I think this is doubtful. I saw them near an inac- 
cessible cliff on Catalina in April, 1911, but I hardly think it likely that they 
nest there, as they had not before been reported from this, probably the most 
often visited island of the group, during the breeding season. 
Eggs have not been taken on Santa Barbara Island, to my knowledge, but in 
April I have found burrows there that undoubtedly belonged to this species. H. 
Wright (77) records what were probably the same burrows, July 4, 1912, and 
the fact that he saw five birds in the vicinity. On Anacapa the same writer 
found the birds to be quite numerous near the east end, but very few nests were 
aecessible. Those examined held either young or egg shells, July 5. At the same 
place D. R. Dickey (JS), in 1913, noted a number of pairs going to and from 
the cliffs, but examined no nests. 
A. yan Rossem and I found the birds to be fairly common at Santa Cruz 
Island during April, 1911, and the fishermen told us that they breed regularly 
near the north end of the island. Although several writers give this bird as a 
common resident there, definite breeding records from the locality seem to be 
lacking, as also from Santa Rosa. 
At San Miguel a large colony makes its home on Prince Islet. J. S. Apple- 
ton and H. C. Burt (10) took fresh eggs there June 6, 1906, while H. Wright 
(11) found young from a few days to several weeks old, July 10, 1912.

Rhinoceros Auklet (8) Grinnell, Bull. Cooper Orn. Club, 1, 1899, p. 18. 
Common in winter near all the islands. In June, 1913, on one of the Coro- 
nados, I found the dessicated remains of a Rhinoceros Auklet which apparently 
had been partly eaten by a Duck Hawk the winter before. C. B. Linton (6) 
took two specimens at San Clemente during the winter of 1908, and J. Grinnell 
(3, 8) reported the species as especially abundant at Catalina during December, 
1897, he having secured ten specimens on the 29th. He states that they were par- 
ticularly wary, swimming under water for three hundred yards or more when 
pursued. 
Dr. Heermann (7) thought that they burrowed on Santa Barbara Island,
