THE CONDOR 
Vol. XVIII 
was noted with large young. On April 15, 1911, one of several nests found, held six eggs 
slightly incubated. The photograph shows the writer suspended at the nest with Carri- 
ger at the top of the cliff. 
75. Speotyto cunicularia hypogaea. Burrowing Owl. Dudley S. De Groot noted 
three of these birds on the hillside just south of Visitacion Avenue, February 24, 1915. 
Each took flight from the ground at the entrance of a burrow. The latter appeared as 
having been used, as excrement and pellets were in evidence. De Groot also informed 
me that he noted several other burrows on the hillside but did not return to make any 
later investigations. 
76. Tyrannus verticalis. Western Kingbird. Jesse Klapp informs me that he 
found three nests in Golden Gate Park during June of the present year (1916), one with 
eggs and two with young.

77. Corvus corax sinuatus. Western Raven. Pair seen at Lake Merced July 23, 
1911, by Carriger. There are unconfirmed records of its having bred there formerly. 
78. Agelaius phoeniceus californicus. Bi-colored Red-winged Blackbird. Rather 
common at the Merced Lakes where Carriger found it nesting. On one occasion there I 
saw an unusual flock consisting of nineteen females and one male. On May 6, 1908, I 
noted a number of pairs nesting in the tules at Mountain Lake, in the Presidio Reserva- 
tion. 
79. Loxia curvirostra minor. American Crossbill. A number collected several 
years ago by Dudley Brown and John Carroll on 19th Avenue near Golden Gate Park; 
skins still preserved.
