摘要：
A pair of courting Grizzly (Brown) Bears (Ursus arctos) was observed on an upper-elevation summit ridge and adjacent slopes for a 12-day period, 1-12 June 1990. The male actively ''herded'' the female by remaining below her and displacing her upslope when she descended. Over half of this upper-elevation mating area was above the elevation known to be Grizzly Bear feeding habitat. Isolation of courting Grizzly Bears in upper-elevation, unproductive habitat, previously reported only from Banff National Park, may occur more commonly in the Rocky Mountains.
