MORE SUMMER BIRDS FOR SAN FRANCISCO COUNTY 
223 
53. Larus californicus. California Gull. Great flocks of gulls were common on 
Lake Merced on every visit. Most of the birds were immatures. 
54. Phalacrocorax auritus albociliatus. Farallon Cormorant. A colony of 500 
nesting on Seal Rocks off the Golden Gate noted by William Leon Dawson, July 21, 1912 
(Condoe, xvii, p. 19). We have seen this bird on Lake Merced during the spring, but 
never in abundance. 
55. Anas platyrhynchos. Mallard. We noted young of the year on Lake Merced 
July 4, 1911, and Carriger also saw parent with small young at Chain of Lakes in Gol- 
den Gate Park, May 22, 1910. 
56. Mareca americana. Baldpate. Recorded at Stow Lake June 5, 1915, by W. A. 
Squires (Condor, xvii, p. 234). 
57. Marila affinis. Lesser Scaup Duck. Female with three young noted on Stow 
Lake in early July, 1913, by George W. Schussler (Condor, xviii, p. 35). 
58. Oidemia deglandi. White-winged Scoter. Seen April 23, 1911, and July 4, 
1911, on Lake Merced by Carriger and the writer. Like the following, the birds seen 
were evidently non-breeders. 
59. Oidemia perspiciliata. Surf Scoter. Noted on April 23, 1911, and on other 
dates. On one occasion Carriger and I captured a crippled bird and it apparently ex- 
pired in our hands. Laid shortly afterwards in the bow of the boat, we were astonished 
to see it leap overboard and splashingly paddle away. 
60. Erismatura jamaicensis. Ruddy Duck. While Carriger and I have found this 
a common bird on the Merced Lakes a careful search revealed no nests. Pemberton 
however, located one May 21, 1902, with two eggs, hidden beneath a canopy of tules on 
the shore of Lake Merced. 
61. Botaurus lentigirtosus. American Bittern. Noted on Lake Merced April 23, 
1910, and on various other dates. 
62. Ardea herodias hyperonca. California Great Blue Heron. Noted at Lake Mer- 
ced April 23, 1910, July 4, 1911, etc. Carriger also found what he believed to be previ- 
ously occupied nests of these birds in a grove of tall eucalyptus on the west shore of the 
lake. 
. 63. Butorides virescens anthonyi. Anthony Green Heron. I noted this bird April 
23, 1910, at Lake Merced. 
64. Nycticorax nycticorax naevius. Black-crowned Night Heron. Noted at Lake 
Merced April 23, 1910, and on other dates. 
65. Rallus virginianus. Virginia Rail. I noted this bird near the north lake and 
found an old nest with scattered egg-shells on April 30, 1911. 
66. Porzana Carolina. Sora Rail. Carriger noted a number of these birds on the 
edge of the tules on the western shore of Lake Merced. 
67. Lobipes lobatus. Northern Phalarope. 
68. Phalaropus fulicarius. Red Phalarope. 
69. Catoptrophorus semipalmatus inornatus. Western Willet. 
70. Actjtis macularia. Spotted Sandpiper. Carriger noted the above four species 
during the spring at Lake Merced. 
71. Oxyechus vociferus vociferus. Killdeer. I have noted this species on the Re- 
creation Grounds in Golden Gate Park, and Carriger also records it as being seen in the 
Park Stadium. Both dates in late spring. Jesse Klapp, the park game warden, informs 
me that he found two nests of this bird in the Park Buffalo Paddock, one with three 
young and one two young during the spring of 1916, and that Killdeer also nested there 
in 1915 though he did not locate the nests. 
72. Accipiter velox. Sharp-shinned Hawk. I noted this bird in the Sutro Forest, 
April 30, 1916. 
73. Pandion haliaetus carolinensis. American Osprey. Carriger noted one of these 
birds in May flying over the Sutro Forest. The nearest breeding point I know of is near 
Hilton, Sonoma County, where Chase Littlejohn found it nesting in August, 1916. The 
nest, about 100 feet up at the top of a giant redwood, was at a bend of the Russian 
River known as Cape Horn and contained large young. The parents were often noted 
at the nest or fishing along the river. 
74. Aluco pratincola. American Barn Owl. Carriger and I found this owl a com- 
mon nester in the high sandy cliffs in the Merced Lakes region. April 23, 1910, a nest
