Collisions with deer spike every November. One surprising factor? Daylight saving time

Timothy Van Deelen is a professor at the University of Wisconsin-Madison in the Department of Forest and Wildlife Ecology. He said the breeding season increases the likelihood of human-deer interactions for three or four weeks each fall.

“The male deer is almost a different animal during the breeding season, behaviorally,” Van Deelen said. “Bucks will dramatically extend their home range, and mature bucks are moving through their big home range trying to find does who are receptive to being bred.”
