We tell our hunters to stay in sight of their blind when going after deer or hogs that they have shot. We do it for a couple reasons; so they don't get lost and two so they don't walk into another hunters area. Several weeks back we had a gentleman and his son shoot a nice 8-point with a 270 Win. The deer ran out of their sight and they followed the rules. They marked blood at the sight of the hit, trailed the buck about 150yds, and stopped when they lost sight of their blind. They then got on the cell phone and called for help.
We called in a neighbor with a tracking dog who arrived in 20mins and we were on the blood trail about an hour later. We left the dog in the truck so not to ruin the dog putting him on a deer that was alive and running and the blood trail was easy to follow.
The buck had lay down another 50yds away but after the man and his son walked back to the blind, the coyotes jumped him up and ran him to death another 100 or so yards down into the ravine. They gutted him, ate both hams, liver, and part of the back strap before we could recover him.
I've never seen them get on a deer so fast you can see in the pictures that the hunter made a great shot.
If you have hungry coyotes, get on the trail fast and stay on it.
Off season predator hunts are in order Or we won't have fawns next year.
