I used a moon-phase calendar to record the days that should have yielded the most mature buck movement (with “mature” defined as an estimated 3 ½ years or older), according to Day’s theory, and then charted every sighting of a mature buck for the last two years. My findings support Day’s theory. This admittedly small sample, limited to Georgia, showed that 37.5 percent of all mature buck sightings occurred on the days predicted, which make up roughly 10 percent of a given month. In other words, the evidence shows that a big buck is 3.75 times as likely to move during daylight on waxing-moon days compared to non-waxing-moon days. The results were even more dramatic for September, when 47.8 percent of all daytime mature buck sightings occurred in the three-day window that Day’s theory predicts.
