At the onset of this season, the bucks neglect their feeding to some extent; consequently those killed have stomachs only partly filled, instead of completely filled, as at other times. By mid-October their fat becomes tinted with reddish, and the whole flesh becomes so rank and musky that it is disdained not only by human beings but even by the Wolves. This condition seems to be considerably more pronounced in the Caribou than in the White-tailed Deer. The hunters forego eating the old bucks for a period of several weeks. Meanwhile the younger bucks, not engaged in mating, remain fit to eat. Hearne (1795: 69) reported the flesh of bucks as still unpalatable as late as December 30.
The rutting season is said to continue through October into November. The end of the period is uncertain, but it may coincide with the shedding of the antlers of the old bucks.

[ Fawns]
Since the fawning takes place far to the north of the Nueltin Lake region, practically no local information concerning it was obtained. Charles Schweder stated that in the spring migration the pregnant does pass to an undetermined distance north of the upper Kazan River (below Ennadai Lake). Although the migration at Nueltin Lake continues throughout June, the rearguard is composed largely of bucks, and the comparatively few does accompanying them toward the last may be barren. Fisher (1821: 199) and Parry (1821: 183) report a small fawn of R. pearyi on Melville Island on June 2. Richardson states (“1825”: 329) that the young are born in May and June. There is evidently some geographical and individual variation in the time of birth (cf. Jacobi, 1931: 232). Apparently the gestation period in the Caribou covers approximately eight months or a little less. In the domesticated Reindeer it is 231 to 242 days, according to Jacobi (1931: 234); in the White-tailed Deer, 205 to 212 days, according to Seton (1929, 3: 258).
Fred Schweder, Jr., stated that he had never found more than a single unborn fawn in any one of the animals he had secured; yet he has seen as many as four fawns following a doe. Of course there is no proof that this individual was the actual mother of so many fawns; a stray or bereaved youngster might well endeavor to attach itself to a foster mother. On August 28, at Little River, I saw a doe being followed by two fawns. On September 16 Fred reported seeing three old does without fawns. Presumably most of the does do not bear young until they are two years old (cf. Jacobi, 1931: 235); thus many yearling does without family cares should be observed during the summer.
