Charles Schweder remarked that the leader of a band is generally a doe; but sometimes it is a buck, or even a fawn. There is virtually no way of telling whether the same doe habitually leads a band. In the big migrant herds, bucks bring up the rear. Once in September, in a herd of about 100 animals, the front half was composed of does and fawns, the rear half of bucks. In the rutting season the does are naturally in the lead, the bucks following them. _References._--Hearne, 1795: 198; Richardson, “1825”: 329; Simpson, 1843: 277, 281, 381; J.

It is fortunate that its range lies so far from the centers of civilization. It is scarcely conceivable that it could survive, as the White-tailed Deer does, in some of our most thickly settled areas. At the river crossings, where I watched the pageant of migration for day after day, some of the animals would come up to within a rod while I handled my cameras in the open, with no more cover than knee-high bushes and rocks (figs. 11, 14). Where else, among the larger creatures of the wilderness, could one find such a close approximation to a Garden-of-Eden existence? Until they detected the human scent, they would stare at me at such close quarters with little more concern than so many barnyard cattle. (For examples, see the section on _Fall migration_.) Moreover, there were occasions when they must have gotten my wind and still did not show panic. There is an obvious deficiency of eyesight or judgment, or both. To account for their behavior on such occasions, I speculated as follows. The species has scarcely any predatory enemies save man, the Wolf, and (perhaps to some extent) the Wolverine. In their normal experience, any such enemy, if within close range, would be making an attack. Thus a questionable figure, not becoming evident to them until they are within close range, and then making no motion to attack, may be dismissed by them as something different and therefore harmless.
