Eight years ago, researchers began outfitting about 800 wild deer in Wisconsin with GPS collars to track their movements. The Southwest Wisconsin Chronic Wasting Disease, Deer and Predator Study is the largest study of CWD the state has ever conducted and aims to better understand how the animals live, move and die.
The enormous library of data they collected has not yet been fully published, but it is already shedding fresh airy on the movements of bucks during estrus and beyond.
