58 PACIFIC COAST AVIFAUNA No. 12 



eapa, March 15, 1911, and A. van Rossem (MS) noted two on Santa Cruz, April 

 25 of the same year. In the latter locality Linton (i) secured a pair during De- 

 cember, 1907, and G. Willett (7) saw the wings of a female tliat was shot on San 

 Miguel in 1910.

Fairly common breeder on some of the islands, but the majority seem to win- 

 ter south of us. I think it doubtful if any of these birds nest on the Coronados, 

 and have seen but one in that locality, this on June 30, 1913. We noted a good 

 many at San Clemente in the early spring of 1915, and were told of a number 

 of nests; C. B. Linton (9) says that they are plentiful at San Nicolas. Present 

 in some numbers at Catalina, but not as abundant as formerly, owing to the de- 

 predations of the tourists. Still every detached rock of any height has its resi- 

 dent pair. C. P. Streator (i) reported the species from Santa Cruz in 1886, and 

 Linton (3) noted one bird there, November 20, 1907. These two are the north- 

 ernmost island records, and it is not believed that the species breeds on the isl- 

 ands, north of Catalina. The time for egg laying seems to vary considerably. I 

 have found fresh eggs as early as March 7, and have watched birds constructing 

 a nest April 28.

Rather rare resident of some of the islands. A. van Rossem (,2) saw one on 

 the Coronados, April 9, 1909. which I am inclined to think was a straggler from 

 the mainland, as no one else has met with it there, and this group has been very 

 thoroughly worked. G. Willett (1) shot a specimen on Santa Cruz, November 20, 

 1907, and A. van Rossem and I saw one there on the night of April 27, 1911. H. 

 C. Burt (4) collected a bird on Anacapa.
