Requisitos

1

Tener la especialidad de Huellas de animales.

Para consejos e instrucciones, véase Huellas de animales.

2

¿Cuál es la diferencia entre moldes positivos y negativos de las huellas de animales?

3

Hacer al menos un vaciado positivo de un molde negativo o un molde de goma.

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.

¿Qué es la coprología y por qué es importante en el estudio de los animales?

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

Encontrar al menos un rastro de un animal que no sean sus huellas. A través de una cuidadosa observación y/o análisis, determinar el mayor número posible de conclusiones de las pruebas encontradas.

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 or damage 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. Beavers, natures engineers, extensively rearrange their surroundings to the benefit of other wildlife and sometimes frustration of humans.

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 - it's owner may be near by and will not want you to disturb it.

Con un compañero, crear una ruta y pista a seguir que abarque por lo menos una milla (1.5 km) de distancia que incluya al menos cuatro cambios de dirección, utilizando las señales tradicionales y que por lo menos dos personas puedan seguir la ruta con éxito. Seguir con éxito una ruta de una milla (1.5 km) establecida por otra persona.

This requirement is a group activity requiring at least 3 (and preferably 4 or more) people. Choose a suitable large park, field, campground, or urban environment (or combination thereof). Divide the group into at least two teams. Each team should set off in a different direction to plot a course that returns to the starting point. When everyone is back, each team follows the other team's course, perhaps with the team who set the course following behind. Remember the point is to correctly guide others through a specific route, not to frustrate the other team and get them lost.

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.

• 

  This is the Trail

• 

  Trail turns left

• 

  Trail turns right

• 

  Danger ahead

Other traditional markers include broken tree branches pointed in the direction the follower is supposed to go. You can also use sticks on the ground to make arrows. Breaking tree branches may not be appropriate in some areas but if breaking the branch helps keep the trail clear it is usually acceptable.

One of the challenges of this requirement is that doing it along an established trail may be somewhat pointless. A large field might make more sense. It could also be completed in an urban area where travel in various directions is very possible but the markers can direct the correct course. On an urban course you can require that the followers provide addresses or record some feature at each turn of the route so you can verify they actually completed the correct path.

It is best if the trail is marked so that each market can be seen from the next, or at least every intersection of trails/roads/paths is clearly marked. Placing the marker a few feet beyond the intersection helps indicate the correct path more clearly.

Have fun.
