YOUNG SCREECH-OWLS. lawless color-variations are called "phases," pos- sibly because they phase the naturalists who try to study out their whys and wherefores. In its food habits, the Sereech-Owl prefers, if it can procure them, mice, grasshoppers, lo- custs, cut worms, beetles, caterpillars, crickets, spiders, lizards, frogs and crawfish. If these are lacking, it attacks the English sparrow and almost any other small bird that comes handy, usually other spai-rows. To show that when very hungry all birds look alike to him, he oc- casionally kills and eats a bird of his own species! Dr. A. K. Fisher's ever useful and scholarly report on the "Hawks and Owls of the United States" sets forth in full detail tne results of the examination of 255 stomachs of Screech-Owls, of which the following is a summary of contents: 100, insects; 91, mice; 12, Enghsh sparrows; 26, other birds; 11, miscel- laneous mammals; 9, crawfish; 7, miscellaneous food; 5, spiders; 5, frogs; 2, lizards; 2, scorpions; 2, earth-worms; 1, poultry; 1, fish, and 43 were empty. The following is a full list of the birds found: 12 Enghsh sparrows, 9 other sparrows, 3 juncos, 2 Screech-Owls, 1 shore-lark, 1 water thrush and 15 unrecognized.
