the auburn study on ft rucker 2013-14 over half the fawns drop were killed by hog or yotes.
That would be pretty close with what happened at our place. 4 dropped 2 left.

I bet coyotes have less of an impact on the deer population in AL than most think. I bet they have more of an impact than you think. Doubtful

I personally think habitat and available food sources have a larger role in deer population than predation. That being said once you've done all you can do to improve habitat and increase the carrying capacity of your property then it's time to manage predators.

the auburn study on ft rucker 2013-14 over half the fawns drop were killed by hog or yotes.
Over half the fawns that were collared on Ft Rucker died...true. We did not document any wild pigs killing fawns...but it has been documented as happening...although it hasn't been documented often. The reality is that every deer population (no matter how healthy or how few predators) has >50% mortality of the fawn crop each year. Does on average will produce 1.7 fawns each year (100 does will drop 170 fawns). Extremely high recruitment rates (fawn:doe ratios when the fawns are about 6 months of age) are around 0.7...meaning only 70 fawns are around for every 100 does. This means that 100 ourt of 170 fawns die (just shy of 60%). Marginal recruitment rates are about 0.5 (50 fawns/100 does...70% mortality rate). If you can keep your mortality rate less than 70%, then you are probably OK. Mortality rates >70% is where we are likely getting into trouble. Keep in mind that fawns die due to LOTS of things other than coyotes and other predators. Malnutrition, abandonment, accidents, parasitism, disease, and others are all significant factors of mortality in even healthy populations...but obviously worse in overpopulated herds. The point is, just because you see fawns disappearing, or you know that coyotes are predating some fawns doesn't mean that your herd is being negatively impacted. It's only when that predation starts to cause overall fawn mortality rates to exceed 70% that you start run into problems.

so its kinda like they don't kill most calves they just find them dead ??? it looks like they killed them ??? I'm not sure what you're seeing...I'm not there. But, I can tell you that counting dead fawns doesn't tell you anything, because you don't know how many you started with. The top deer minds in the country are all saying that fawn recruitment rates are the best information you can collect regarding your fawn crop. And...it can be done with game cameras...which most people have.

Shoot the yotes when you can but trap 'em year-round or let someone do it.
Hunting them is fun. Trapping them is more effective and beneficial in the long run, just like with hogs. Do both.

Steve Ditchkoff,, NightHunter , Matt or who ever .
do you think coyotes or more of a scavenger or a predator when they utilize deer meat as a diet source .
