There are, it is true, excep-tions, but every close student of bird-life must be so im-pressed with the dangers to which birds are exposed, thathe can not doubt that the chief object of color is usuallyfor its wearers concealment. The term protective coloration has lately receivedfresh significance through the studies of Mr. Abbott H.Thayer.* Mr. Thayer proves conclusively that protect-ive coloration lies not so much in an animals resem-blance in color to its surroundings as in its gradation ofcolor. Thus he points to the fact that, as a rule, animalsare darker above than below—that is, those parts receiv-ing the most light are darkest, while the parts receiving theleast light are palest. In effect it follows that the darkerupper parts are brightened, while the paler under parts are * See his papers *on The Law which Underlies Protective Colora-tion, in The Auk (New York city), vol. xiii, pp. 124-129, 318-320, elevenfigures.</i><br><b>Text Appearing After Image:</b><br><i>Plate XII.

The upper half ofthe other decoys is treated in exactly the same manner,but their lower half is graded to a pure white on the me-dian line below.
