3) Low & Slow
Now you have no idea where it went?? Everything that walks, leaves a trail. The trick is finding it!
Blood can be anywhere. Blood soaks the hair, long before it hits the ground. Squat or kneel (sit? Hey, I'm old)
and look 2-3 feet off the ground in every direction. Many times, you will find more blood on trees and leaves, than you will on the ground. Once an animal gets into heavy cover, they brush against all kinds of things. Blood gets transferd to trees, sticks, logs, leaves, etc.
4) Not just blood!
Remember, you are following a trail. Any animal walking through the woods, will leave sign that it has been through there. The easiest to find and see is overturned leaves. Get your head a foot or so off the ground, and you can easily see a trail of overturned leaves, going in a certain direction. I have actually laid on the ground, and picked up a trail of overturned leaves! Also, The sign has told you, that this animal is hit hard... A hard hit, hurting animal will stumble!! This will be easy to see once you know what you're looking at. ALWAYS remember!! Look around, left & right, you should be scanning a half circle in front of you the entire time...
5) Mark the trail
I have never carried TP or surveyors tape, to mark trails. IT IS a good idea, should you choose to do so!!
I have always marked my sign, buy simply breaking a small branch. The important thing, is to make a mark, and that YOU know what it is and what it means!!
If you loose the trail? If you loose the trail, go back to your last mark, and make widening half circles in the general direction the animal was traveling. Another thing to remember is, ALWAYS look behind you!! By lineing up your marks, you will be able tell the direction of possible travel.
6) When in doubt, Down Hill
In my 40+ years of doing this... I have NEVER seen a fatally hit animal, go up hill for a long distance.
I have seen them go up hill to get to thick cover, and up hill because they were pushed that way.
7) WATER
A hard hit, fatally wounded animal, always heads for water!
When all else fails... Check every spring, brook, creek, pond, etc. you can think of!!
This is just one old woodchuckers experience.... OMMV
