It is just my observations from the field and nothing to prove it scientifically, but I tend to see a lot of deer during new moon times. I see them lateer after sunrise (morning hunt) and see then earlier at sunset (evening hunt). I suspect that it has to do with the lack of light to forage by. Have you ever notice how freaking dark it is at 12pm without a moon??? Gotta effect a deers vision to some degree.
