capa, Mareh 15, 1911, and A. van Rossem (MS) noted two on Santa Cruz, April 
25 of the same year. In the latter locality Linton (4) secured a pair during De- 
cember, 1907, and G. Willett (7) saw the wings of a female that 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 (4) 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.
