The American natural history : a foundation of useful knowledge of the higher animals of North America. times I have seen dried frogs hanging upon thorns,where they had beenplaced when fresh byShrikes. Every Shrike is afeathered Jekyll andHyde. In summer andautumn his harvest of in-sects is everything thatcould be expected. InDr. Judds Bulletin , Biological Survey, De-partment of Agriculture,the list of groups of insects destroyed by the LoggerheadShrike fills a page, and includes such pests as caterpillars,cut-worms, canker-worms, grasshoppers, crickets and weevils. But mark the winter and early spring record. Thirteenspecies of small birds are numbered among the Loggerheadsvictims, of which five are sparrows, and others are the grounddove, chimney swift, Bells vireo and snow bunting. TheButcher Bird is known to kill twenty-eight species of birds,some of them valuable insect-destroyers, and none of themto be spared without loss except the English sparrow. Onthe other hand, this bird is a great destroyer of wild mice,which in cold weather form one-fourth of its entire ^JS^ LOGGERHEAD SHRIKE. 290 PERCHERS AND SINGERS The Loggerhead also feeds freely upon lizards, snakes, frogsand fish, when they are obtainable. The Butcher Bird is adeadly enemy of the English sparrow, and kills and eatsthem so industriously that in Boston certain city officialsonce felt called upon to order the Shrikes to be shot. The table on the opposite page is a very full exposition ofthe food habits of the two members of the Shrike Familyreferred to. The Great Northern Shrike is able to sing, but seldomdoes so; and many of his friends think he sings not at summer it ranges all the way to Cook Inlet, Alaska, andin winter it migrates as far south as Virginia. In the southernstates it meets the Loggerhead Shrike, and the two speciesso strongly resemble each other that they are like twofeathered Dromios.
