July, 1920 AVIFAUNA OF FORRESTER ISLAND, ALASKA 139 
the writer’s belief that this species is a regular breeding bird in the locality, not 
having been previously recorded as such, by reason of the fact that it has been 
confused with its relative, H. wu. ustulata. 
During 1919 most of the breeding birds of the locality were present in the 
usual numbers and nesting as has been previously described. A considerable pro- 
portion (probably at least half) of the Pelagic Cormorants present at the island 
apparently failed to nest this summer, and three eggs was the complement of 
most of those that did nest. This irregularity of the species in nesting has 
been frequently observed by the writer during past seasons, but whether it is 
eaused by fluctuation of food supply or other reasons is still unknown to him. 
There was apparently as much food for the cormorants this year as during 1917, 
when all the birds appeared to breed, with four eggs the smallest number ob- 
served in a nest and five eggs not unusual. 
One nest of the Pigeon Guillemot containing two eggs was found June 12, 
the first time the writer has noted this number on the island. While this is the 
usual nest complement along the California coast, none of the nests previously 
noted by the writer on Forrester Island (probably a dozen or more), contained 
more than one egg or, young. 
Seven nests of the Townsend Sparrow (Passerella iliaca townsend) were 
observed on various dates between May 26 and July 5. As usual, the situations 
of these nests varied greatly, two being well up in trees, two on the ground, and 
the others among moss and grass on sides of decayed stumps and fallen logs. 
four out of these seven nests contained four eggs each, a number found very 
rarely during previous years, three being the usual complement. 
Out of four Lutescent Warblers’ nests noted, three contained five eggs each 
and the other four, a rather large average for sets of this bird. 
Unusually rough weather during most of the early part of the month of 
May made travelling on the water very difficult or impossible, consequently few 
notes on the migratory water birds were obtained. Pacific Loons, though not so 
abundant as during some former springs, were frequently seen flying northward 
from May 2 to May 20, and one was noted as late as June 7. Several Sabine Gulls 
were observed outside the island June 8, the only time the species was seen 
during the summer. An immature Bonaparte Gull appeared in the bay July 26, 
the second record for the locality. Large flocks of Northern Phalaropes arrived 
June 12, and the species was rather common for several days thereafter. 
Aleutian Savannah Sparrows (Passerculus sandwichensis sandwichensis ) 
were common during the spring migration from May 6 to 20 and were seen in 
diminished numbers until May 26. Golden-crowned Sparrows were unusually 
plentiful from May 8 to 19, and White-winged Crossbills were noted on two 
occasions, on May 15, when several large flocks were seen at the south end of 
the island, and May 24, when a flock of half a dozen birds appeared at camp. 
Sitka Crossbills were more or less plentiful during the entire summer, but no 
indication of their breeding was noted. 
Marbled Murrelets with full-grown young appeared July 31 and were com- 
mon at the time of our departure from the island, August 8.
