 224 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- get at the top of the cliff. 75. $peotyto unicularia hypogaea. Burrowing OwL Dudley S. De Groot noted three of these birds on the hillside just south of Visitation Avenue, February 24, 1915. Each took flight from the ground at the entrance of a burrow. The litter 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 verticalia. 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. Fig. 55.

Pair seen at Lake Merced July 23, 1911, by Cartiger. There are unconfirmed records of its having bred there formerly. 78. Agelaius phoenlceus callfornicus. Bi-colored Red-winged Blickbird. Rather common at the Merced Lakes where Carrlger 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. 80. Carpodacus purpursus californicus. California Purple Finch. Abundant in
