maybe the deer don't go nocturnal but in December they sure show up later in the evening, like closer to dark.
No-one is hunting my property or the property that borders my property. My son and family live on our property. Spoke with him today. Seeing very few deer, late and closer to dark.
I would call that, going nocturnal.
I think most everyone who has been hunting for years knows that the later in the year it gets the later the deer come out especially after gun season and in December.
