[Vigilance and fearfulness of reindeer: population differences].
Distances of detection and flight away of reindeer disturbed by approaching human on foot were used to compare reindeer alertness and vigilance. Population differences depended on genetic origin (wild, feral, and tame reindeer) and hunting. No correlations of vigilance and alertness were found with presence of predators, sex composition of herds, and presence of newborns in herd. Herd size affecting jointly with genetic origin or hunting had negative correlation with alertness.
