Blood Stain Pattern Interpretation The average amount of blood in a deer is 1 ounce of blood per pound of body weight. Example 160lb. = 5 quarts of blood.<Live weight> The amount of blood loss to affect a deer not including any body injury is approximately 32 ounces with death coming at about 45 ounces of blood loss. Most likely they are going to die from trauma injury rather than bleed to death. Spot size how big is the drop? The more impact energy the smaller size the blood drops. IMPACT SITE PATTERNS High Velocity Impact Splatter caused by gun fire will leave blood drops at site of impact about 1 MM OR .03937 INCHES in size which is almost invisible even in the snow. DO NOT BE FOOLED INTO THINKING THAT THE ANIMAL WAS MISSED. Medium Velocity Impact Splatter caused by bow and arrow impacts will, on the other hand, will leave a droplet of almost 3 MM in a smaller area that gun shot splatter, but is still going to be hard to see in most cases. From here we have a trail in many or most cases of a running animal. Running does raise blood pressure increasing blood flowing from wound, but it spreads this blood over a larger area. A deer that is running full speed 35 mph can cover 188.22 yards in 11 seconds. How long did it take your deer to die? If you have a choice stay off the trail and away from the spot of impact for at least 20 minutes most unfound deer are pressured into running and also into HIDING making for a very difficult recovery. Wipe Pattern – Do not make one, as it will alter the facts! If you walk on the trail the animal takes you will alter the blood pattern making it even more difficult to follow. Always walk on the side of the trail if you have a narrow space walk around and pick up the trail on other side of the obstacle. Always mark your trail. Toilet paper works well, but do not use white if you can help it or be very careful not to wave it around making you look like a fleeing deer. A pattern with lots of large drops most likely come from mouth or from standing animals. The largest amount of blood loss from impact is from the side of animal that has the exit wound. Many times we have a trail that has a small amount of blood then a trail of twice as much blood and then nothing many times what has happened is the animal has revisited the trail IE… Made a 180-degree turn and walk both directions on the trail and made a cut off. Many times an animal will come to a field, road, person or has a reason not to go any farther. Animals have a tendency to try to go back to where they were before being wounded because they were safe there. IE… <Bedding area> usually in curved or arcing trails. Blood droplets that are round fall at a 90-degree angle to the terrain. Blood droplets that are tear drop shaped fall onto a surface that is not flat or from a moving animal the point on the teardrop will indicate direction of travel. Remember that a surface that has a slant or angle will cause tear dropping as the blood rolls or slides down from gravity. Angle of impact can change blood patterns. Horizontal shots leave less blood then vertical. There is less resistance to blood traveling in a downward motion than a horizontal motion also there is less chance of blood build up in the body cavity. Lung shots and arterial shots have the most blood loss. Many times from forward splatter. About 4 to 7 seconds after a lung shot, blood will expel out of the mouth and nose if there is enough volume. This makes it harder to get oxygen into the body as lung volume is greatly reduced causing cramping, light headedness, confusion and even drowning. Arterial bleeding in many cases will cause gushing and fine mist spraying, so be careful as this can also happen with a leg wound. Neck wounds are usually a case of very heavy bleeding and a lot of side to side movement when moving. Transfer patterns happen when the animal rubs against something like trees, fences, grass, and the ground when they fall or lay down these are important because the animal is in panic or leaning against the trees and fences or just running into them. When they lay down they are having trouble traveling or are hiding. If in doubt of a clean hit or if the trail is less than 1 hour old stop and think about waiting when an animal lays down and then moves. The animal, in most causes, has been pushed it WILL LIE DOWN AGAIN SOON. Maybe for the last time. People have a hard time tracking because they have pushed the animal into fleeing farther. Even if darkness is close there is no reason to push. Products have become available to find even blood washed away by rain. Again rarely do animals die from blood loss. They die from trauma many times the blood can not even be seen. Don’t be fooled. Turn doubt into success by checking every trail with BlueStar®. It will immediately tell you if there was a hit. |
