It is said that the attachment between a doe and its fawn is such that when one of them is killed, the hunter can approach within 50 feet of the surviving doe or within 20 feet of the surviving fawn. A fawn is apt to linger for days in the vicinity where its dam has been killed. Charles Schweder has never seen fawns playing with each other or with their mothers; two or three times he has seen one frisking by itself--such as jumping about or running in a circle--but never for more than half a minute at a time. Seriousness of life for a Caribou seems confirmed from its infancy. In the hard winter of 1944-45, when the Caribou were tired and hungry, Charles had the rare experience of driving his dogteam right through herds on Nueltin Lake; the animals merely moved aside enough to let him pass. In like vein Joe Chambers spoke of encountering such numbers of migrating Caribou on or near the “Little Barrens” south of Churchill in the spring of 1947 that his dogs “went wild” and he had to halt for a time; the animals came within about 100 yards of his team. A Caribou bold enough to attack a man is very rarely heard of. Yet that was the experience of 15-year-old Anoteelik on September 8. Having run out of ammunition, he undertook to kill a 2-year-old buck with a rock in a patch of timber. (Possibly the animal had already been wounded with Anoteelik’s .22 rifle.) When the missile failed of its mark, the buck made for the boy, who escaped by climbing a tree. Perhaps this is the first case on record of a man or a boy (especially an Eskimo!) being treed by a Barren Ground Caribou. Jenness mentions (1922: 150) a case of an Eskimo being fatally gored by a Caribou on Victoria Island. Otherwise, under all general circumstances, and in contradistinction to the Bison, the Muskox, the Moose, and even the White-tailed Deer, the Caribou may be regarded as quite innocuous to man. The restlessness so frequently exhibited by Caribou during the summer, in trotting rapidly over the Barrens or in feeding hurriedly here and there while constantly forging ahead (in contrast to the placidity of grazing sheep and cattle), may be attributed in large part to the relentless scourge of fly pests.
