MORE SUMMER BIRDS FOR SAN FRANCISCO COUNTY

western half of the County, and undoubtedly nests there as I have found it breeding in 
similar localities just south of the line. Through an oversight I omitted this bird from 
my original list. 
81. Astragalinus lawrencei. Lawrence Goldfinch. While 1 have found nests of 
this species just south of the County line my only record for our County is of a male 
seen March 19, 1916, near the Sutro Forest. 
82. Spinus pinus pinus. Pine Siskin. An erratic breeder in various portions of the 
County. In 1892 a school chum lowered down a set of eggs from a nest, in the “Panhan- 
dle” District of Golden Gate Park, which for years I was unable to identify. A few 
years ago I found a sparsely marked set of Siskin eggs which are in every way identical. 
On March 16, 1916, south of the Park on a city street I noted a Siskin gathering material 
for a nest. 
83. Passerculus sandwichensis bryanti. Bryant Marsh Sparrow. While neither 
Carriger nor I ever succeeded in finding a nest of this bird north of the County line 
there is a set of four eggs in the Museum of Vertebrate Zoology (no. 1463) taken by L. 
P. Bolander in a field near Lake Merced May 8, 1905, which I believe constitutes the 
only actual record of this bird’s nesting in our County. 
84. Spizella passerina arizonae. Western Chipping Sparrow. While not an uncom- 
mon breeder close up to the County line my only record here is April 20, 1908, when I 
noted a bird at Bosworth and Milton streets, in the Mission District. 
85. Junco oreganus pinosus. Point Pinos Junco. This rather common resident 
species is unquestionably to be found nesting, as I have noted it at all seasons. Just 
across the County line I have collected several sets of eggs, and Pemberton also secured 
skins which proved typical pinosus. In view of this, the occurrence of thurberi on June 
5, as recorded by W. A. Squires (Condor, xviii, p. 202), would be all the more remarka- 
ble; but Carriger and I feel we must question that record unless specimens were taken 
to substantiate it. Jesse Klapp tells me that he found a Junco’s nest (no doubt referable 
to this species, i. e., pinosus) with two nearly full grown young in Golden Gate Park dur- 
ing the spring of 1916. 
86. Pipilo crissalis crissalis. California Brown Towhee. Jesse Klapp found a nest 
of this bird in Golden Gate Park in the spring of 1916, with four eggs. Neither Carri- 
ger nor I have seen it north of the County line. The California Brown Towhee is really 
such an abundant species in San Mateo County, in exactly similar country, that its 
rarity here is more remarkable than its abundance would be. 
87. Passerina amoena. Lazuli Bunting. Pemberton noted a pair carrying nesting 
material near Ashbury Heights a number of times between June 1 and June 10, 1915, but 
did not succeed in locating the nest. 
88. Piranga ludoviciana. Western Tanager. Recorded as being seen in Lafayette 
Square, May 6, 1908, by Clark C. Van Fleet (Condor, x, p. 181). 
89. Progne subis hesperia. Western Martin. Carriger saw several at Lake Merced, 
April 28, 1912. 
90. Riparia riparia. Bank Swallow. A very common nester in the sand banks at 
Lake Merced. A colony was noted nesting April 23, 1910. The only nest Carriger and I 
excavated contained a single fresh egg. 
91. Vireo huttoni huttoni. Hutton Vireo. While rather common and undoubtedly 
breeding within the County neither Carriger nor I have a definite nesting record. A 
pair noted in Golden Gate Park, March 5, 1910 (Carriger) ; noted at Lake Merced April 
23, 1910 (Carriger and Ray). 
92. Vermivora celata lutescens. Luteseent Warbler. Carriger noted two of these 
birds near the Hayes Street entrance to Golden Gate Park, March 5, 1910. He also noted 
birds feeding young on Strawberry Hill; the exact date however is unavailable, as his 
records before 1906 were destroyed in the great fire of that year. 
93. Dendroica auduboni auduboni. Audubon Warbler. This is a county that pro- 
vides a proper summer environment for the Pine Siskin, so the Western Robin (re- 
cently recorded) may yet be found to have this warbler as a summer companion. The 
nearest breeding station I believe is Sonoma County (Grinnell, Pac. Coast Avifauna no. 
11, P- 148). My latest dates here are March 25, 1906, April 1, 1906, March 31, 1907, March 
19, 1911, March 27, 1915, and March 24, 1916. 
94. Geothlypis trichas sinuosa. San Francisco Yellowthroat. A common breeder 
in the Lake Merced region. I found three typical nests April 22, 1911; two with four
