December has always been a challenge where I hunt. It appears to be the beginning of the breeding season, where coyotes are starting to pair up and stake out a territory.
I've written about this in the past, but will repeat my observations:
Mid-December, while goose hunting, I see spots in the snow way to the N of me. Bino's show it is 2 groups of coyotes, about 50-100yds apart. Each group has multiple coyotes in it, with 2 coyotes about 10yds from each group.
I tried distress calls, with no success, just a couple of looks in my direction. Switching to vocals, the same thing, not one came to investigate.
I watched them off and on for a few hours. The only movement was when a coyote from a large group got up and walked around the 2 a few times, then went back to the big group and laid down. This happened repeatedly.
The next year, about the same time frame, at about the same place, the coyotes were doing the same thing. And, still no interest in my calls, distress or vocals.
I suspect, but can't prove, that the larger groups were males and the smaller groups were females. A male would get up, circle the girls, and do a 'sniff' check to see if the girls were ready for mating.
Thinking back to my single male years, the possibility of having sex far outweighed any desire for food, and I believe this is what I was watching.
By late December or early January, the calling success goes back to normal, but this time I'll get more pairs coming in.
