Adventist Youth Honors Answer Book/Nature/Animal Tracking - Advanced

2. What is the difference between positive and negative casts of animal tracks?
When the first cast of an animal track is made by pouring the casting material into the track, the result is a negative cast. It is called a negative cast, because rather than looking like the animal's track, it takes the shape of the animal's foot which made the track. A positive cast can be made by casting a negative track, and the result looks like the track left by the animal.

3. Make at least one positive cast from a negative cast or rubber mold.
To make a positive cast from a negative cast, you will need a container at least the same size as the animal track. Lubricate the negative cast with petroleum jelly so that it does not stick to the positive cast. Then mix up some plaster, pour it into the container, and place the negative cast on top of the plaster. Press it in and vibrate it so that all the air pockets are removed and all the spaces filled. Leave it alone while it sets. If it was lubricated sufficiently, the casts should come apart easily after the plaster sets.

4. What is scatology and why is it important in the study of animals?
Scatology is the study of feces. Scatological studies allow one to determine a wide range of biological information about a creature, including its diet (and thus where it has been), healthiness, and diseases such as tapeworms. Animal feces dries, cools, and decays as it ages, so it can also tell the careful observer how long ago the animal was present. The presence (or absence) and type of insects "feasting" on scat is another important clue to when it was deposited.

5. Find at least one trace of an animal other than its tracks. Through careful observation and/or analysis determine as many conclusions as possible from the evidence.

 * Scat: As discussed in the previous requirement, scat can tell many things about an animal.
 * Fur, feathers, skin, and antlers: Animals sometimes leaves bits of themselves behind. Birds drop feathers when they molt, or when they are torn from them by a predator.  Egg shells are kicked from nests.  Animals catch their fur in trees and thorns.  Snakes and other reptiles shed their skin, and deer and moose shed their antlers in the fall after the rut.
 * Cuttings: Cuttings are things such as acorn shells which have been nibbled on. Deer and squirrel often leave them behind.
 * Scratches on trees: Bears, members of the cat family, and other predators will sharpen their claws on tree trunks. Sometimes they will do this to mark their territory.
 * Scent Posts: Many animals mark their territory by urinating on trees or other prominent items. If you are walking through the woods and smell a strong musky odor, look around — you may find other sign.
 * Carcasses: A half eaten carcass must have been eaten by something! Large predators sometimes eat their meals infrequently, so when they bring down large prey, they will gorge themselves on it to the point where their stomachs will take no more.  They will sometimes hide the rest, or rest nearby while they digest what they have eaten, and then come back for more.  If you find a half-eaten carcass, be careful - its owner may be near by and will not want you to disturb it.

==6. With a partner set up a track and trail course covering at least one mile (1.6 km) which will include at least four change-of-directions utilizing traditional native signs and have at least two other persons successfully follow the route. Successfully follow a one mile (1.6 km) route set by someone else. == Here are a few traditional markers constructed with rocks. Note that the "turn" markers are constructed so that the smaller rock on the ground points in the direction of the trail.
