[pagebreak] The Weather Trigger
Rod Bohn operates Wildlife Adventures (800-850-9214, bchunter.com) and guides hunters to mule deer migrating out of British Columbia's Wells Gray Provincial Park. Here, in the northernmost reaches of the mule deer's range, a hunter can mark his calendar by the stages of the deer's migration. Bohn says the migration out of the park's mountains comes in three waves: does and fawns beginning on October 15, followed by young bucks on November 1 and mature bucks on November 15. "My partner, Ron Emmelcamp, has been watching this migration for forty years, and he says it's set in motion by the shortening amount of daylight in the fall, just like what triggers the rut," says Bohn.
