The Minds and Manners of Wild Animals: A Book of Personal Observations

XV THE MENTAL TRAITS OF BIRDS In comparison with mammalian mentality, the avian mind is much more elementary and primitive. It is as far behind the average of the mammals as the minds of fishes are inferior to those of reptiles. Instinct Prominent in Birds. The average bird is more a creature of instinct than of reason. Primarily it lives and moves by and through the knowledge that it has inherited, rather than by the observations it has made and the things it has thought out in its own head. But let it not for one moment be supposed that the instinctive knowledge of the bird is of a mental quality inferior to that of the mammal. The difference is in kind only, not in degree. As a factor in self-preservation the keen and correct reasoning of the farm-land fox is in no sense superior to the wonderful instinct and prescience of the golden plover that, on a certain calendar day, or week, bids farewell to its comfortable breeding-grounds in the cold north beyond the arctic circle, rises high in the air and launches forth on its long and perilous migration flight of 8,000 miles to its winter resort in Argentina. The Migrations of Birds. Volumes have been written on the migrations of birds. The subject is vast, and inexhaustable. It is perhaps the most wonderful of all the manifestations of avian intelligence. It is of interest chiefly to the birds of the temperate zone, whose summer homes and food supplies are for four months of the year buried under a mantle of snow and ice. All but a corporal's guard of the birds of the United States and Canada must go south every winter or perish from starvation and cold. It is a case of migrate or die. Many of the birds do not mind the cold of the northern winter--if it is dry; and if they could be fed in winter, many of them would remain with us throughout the year.
