Common resident aliout the northern islands. J. G. C-ooper {!) recorded 

 this species from San Clemente in the sixties, and Willett {14) saw three birds 

 near San Nicolas, June 26, 1911. I have seen a few near Catalina during April, 

 and J.- Grinnell {8) noted several in the same locality in December, 1897. The 

 most southerly breeding station recorded is Santa Barbara Island, where J. Grin- 

 nell {8) found fresh sets of eggs May 15, 1897, and H. Wright {15) saw birds 

 carrying food into the caves July 8, 1912. 



D. R. Dickey {MS) says that on Anacapa, June 22, 1913, these birds were 

 nesting in almost every tidal cave. Sites Avere chosen well back in the dark, 

 where the dripping water and dank moisture would seem to make it impossible 

 for eggs to hatch, but, nevertheless, most of the nests contained young. 



H. Wright {15) found them breeding in considerable numbers near the 

 north end of Santa Cruz Island, July 10, 1912, and A. van Rossem and I saw sev- 

 eral off shore from Prisoners Harbor, April 24, 1911. On San Miguel, G. Willett 

 {12) says they were breeding commonly in the caves and niches all around the 

 island. On June 23, 1910, he found the contents of the nests to vary from fresh 

 eggs to young of all sizes.

 der, Condor, xv, 1913, p. 88. (//) Grinnell, Pac. Coast Avif., 11, 1915, p. 19. 



Records from the mainland indicate that during the winter, this bird may be 

 found as far south as Catalina at least. During the spring they occur in some 

 numbers in the vicinity of Santa Cruz Island, where A. van Rossem and I en- 

 countered them in April, 1911, but the only place in this group where they have 

 been found breeding is on Prince Islet, near San Miguel. J. S. Appleton and H. 

 C. Burt (5) discovered this colony on June 6, 1906, and took fresh and slightly 

 incubated eggs. H. Wright (.9) states that on July 12, 1912, there were several 

 small colonies there, aggregating probably one hundred pairs, which at this date 

 mostly had young.
