It is a true harbinger of spring,and its delightful little song is trilled forth fromthe top of some green shrub in early Marchand April, before most of our other songstershave thought of leaving the sunny South. Songsparrows vary much in habits, as well as insize and coloration. Some forms live alongstreams bordered b) deserts, others in swampsamong bulrushes and tules, others in timberedregions, others on rocky barren hillsides, andstill others in rich, fertile valleys. With sucha variety of habitat, the food of the speciesnaturally varies considerably. About three-fourths of its diet consists of the seeds ofnoxious weeds and one-fourth of insects. Ofthese, beetles, especially weevils, constitute themajor portion. Ants, wasps, bugs (includingthe black olive scale), and caterpillars are alsoeaten. Grasshoppers are taken by the easternbirds, but not by the western ones. 14. f ^ f^^^l w -j^ \^ ¥1 \ P
