After looking at moon conditions and hunter sightings for many years, I suspect the moon has an influence on deer movement, but it is probably one of the weakest of all the environmental influences. The strongest correlation between moon conditions and hunter sightings is simply the difference between a waxing moon and a waning moon. When comparing identical "percent of the moon's face illuminated" numbers for waning versus waxing moons, waning moon days produce higher sighting rates. Why this is, I have no idea. Early on, I suspected the difference was that a waning moon is up in the sky at sunrise, while a waxing moon is in the sky at sunset. So I looked at morning versus evening hunt data for the two different conditions. Turns out waning moon sightings were higher both for morning and evenings compared to a waxing moon. Again, no idea why.
