(WFRV) - The Wisconsin Department of Natural Resources (DNR) has collected data revealing unusual movement patterns in two GPS-collared white-tailed deer during the breeding season. The DNR says that this study may be beneficial for hunters gearing up for the fall hunting season, as many hunters keep an eye on specific bucks as their antlers grow and monitor the arrival of new bucks. The study, conducted from November 11 to 13, 2020, tracked two mature bucks within the Wisconsin DNR's Deer and Predator Study area. Over the 36-hour period, GPS data was collected every hour, monitoring Buck A (collar 40440, marked in blue) and Buck B (collar 29536, marked in pink). The data collected suggests Buck A was 4.5 years old and Buck B was 3.5 years old. According to the DNR, buck movement differs by age, which could reflect their breeding strategies and success. Buck Interaction Buck A vs Buck B - Wisconsin DNR The DNR's study states that at first glance the patterns look like "zig-zagging" tracks, but after breaking down the data, interesting behaviors emerge such as high activity at dawn and dusk, moving for periods of time without rest, and interactions between non-GPS-collared deer. The study shows the two bucks interacted as many as five times during this period. Buck A's movement stayed consistent during the day and night, on the move for almost 24 hours straight. DNR: Invasive fish species detected in Wisconsin Buck B's movements during the study, were more relaxed and short, showing he might have been following an estrous doe—a female deer ready to mate—likely competing with uncollared bucks along with Buck A.
