I can't remember where I read this but apparently coyote, hogs, etc can add to or reduce their breeding cycle to offset hunting pressure. Maybe it was this thread but I didn't find it on a fast look thru.
At 1,500 yards?
Idk... my .338 Edge 300 SMK's still have 1342 fps / 1199 fpe at 1,500 (using Bullet flight to calc based on actual load velocities). My .308 loads (168gr SMK) are at 895 fps / 299 fpe at 1,500 yards.
Yes diapause is when they delay development of the embryo until conditions in the uterus are exactly right. Stress and food sources can cause them to do it but it's not a conscientious thing, it just happens when their body isnt up to it. I think science believes all mammals can do it but it's usually not necessary, or it happens in a few animals of a herd because they're competing for food. I think it's only believed to be able to put it off a couple of months and then the embryo dies and is flushed or absorbed.In 30 years of doing predator control work I have kept records that show coyote have more pups when their numbers are lower and fewer when their numbers are higher . This also correlates to the food base being higher or lower . I suspect that this will apply to hogs as well more food more piglets less food less piglets . I haven't seen where the coyote bread earlier or latter depending on hunting pressure but then where I live there hasn't been less hunting pressure on the coyote in my life time . The coyote in sheep country is probably the most persecuted animal on earth with a reason for it . Peoples livelihood .
Someone mentioned pigs were practically blind, I have not found this to be the case as we have watched them watching us as we approach from ~500 yards away. They look up until we stop moving then go back to feeding and when we move again they watch us. They may only see an off color blob in a hillside of grass or think we are a cow but they can definitely see us. I would say they have eyesight more like a human and not as good as a coyote or a hawk. They can see good at night but feel more relaxed from my experience.
That's funny right there!There is another kind of cattle. We hunt PA for deer in cattle fences. We park really low and hunt high. When we got back to the truck they had licked the whole truck to get the salt from the roads.
