Patchek 1943 Amphispiza belli June 12 2 mi SE Beegum, 1650 feet, Tehama Co., Calif. Occurs commonly in the Adenostoma of the north slope and ridge. The species appears consistently confined to that vegetation type. They appear more abundant in areas where the Adenostoma is pure and where the individual plants are only 3-4 feet high and more or less spaced apart. Four adults and one fully grown juvenile bird were taken. Occasional song heard. June 13. Found abundant on the south slope, occurring in exceptional numbers throughout most of the Adenostoma. Again, pairs were most densely distributed in Adenostoma, plants of which were short and more or less spaced apart. Under seeming optimal conditions, pairs were found approximately 75 feet one from the other, distributed in a loose checker-board manner. In older Adenostoma (plants approx 5 feet high) Bell Sparrows were less abundant. They were absent from tall, dense Adenostoma. One male taken this morning was carrying a beak-full of a small green lepidopterous larva present in the Adenostoma.
