Final answer:
The description in 'Of Wolves and Men' does not include wolves preparing to hibernate since wolves do not hibernate. The fall changes described include the accumulation of fat in moose and elk, the thickening of wolves' underfur, and behaviors associated with energy conservation and preparation for winter.
Step-by-step explanation:
In the book Of Wolves and Men, the author describes various events that occur in the fall except for "wolves preparing to hibernate." Wolves do not hibernate, and this behavior does not apply to them. Instead, other changes take place during the fall such as:
- Moose become fat, which is a buildup of energy reserves for the harsh winter.
- Thickening of the wolf's underfur to provide better insulation against the cold.
- Wolf pack hunting practices, may vary but do not include hunting separately as a regular seasonal change.
Hibernation is a state that some animals, like grizzly bears, enter to conserve energy during periods when food is scarce, mainly in winter, not fall. The fact that hibernation is triggered by environmental cues is evidenced by the non-random nature of the process, as alluded to in the provided text regarding grizzly bears not entering hibernation at the beginning of autumn or at random times throughout the year.
