A few songs and more frequent "k.mrn." sing notes disclosed a number in this chaparral, which in general aspect is quite like my study area above Arcades, Los Angeles Co., Calif. when tits are, however, either less abundant here, or, greater silence at this time of year makes them more difficult to find.
