They vary from light brown to black, with short hair and a light belly. The ears and tail have little hair. The hind feet are short compared to Apodemus mice, only 15–19 mm long; the normal gait is a run with a stride of about 4.5 cm, though they can jump up to 45 cm. The droppings are blackish, about 3 mm long, and have a strong musty smell. The voice is a high-pitched squeak.

− | ;Weasels: Weasels vary in length from 15 to 35 centimeters (6 to 14 inches), and usually have a light brown upper coat, white belly and black fur at the tip of the tail; in many species, populations living at high latitudes moult to a white coat with black fur at the tip of the tail in winter. They have long slender bodies, which enable them to follow their prey into burrows. Their tails are typically almost as long as the rest of their bodies. As is typical of small carnivores, weasels have a reputation for cleverness and guile. They also have tails that can be any where from 22-33cm long and they use these to defend the food they get and to claim territory from other weasels.

| |
− | | description = Adult frogs are characterized by long hind legs, a short body, webbed digits, protruding eyes and the absence of a tail. Most frogs have a semi-aquatic lifestyle, but move easily on land by jumping or climbing. They typically lay their eggs in puddles, ponds or lakes; and their larvae, called tadpoles, have gills and develop in water. Adult frogs follow a carnivorous diet, mostly of arthropods, annelids and gastropods. Frogs are most noticeable by their call, which can be widely heard during the night or day, mainly in their mating season.

They range in size from the relatively small jackdaws (still larger than most other passerines) to the very large Common Raven of the Holarctic region and Thick-billed Raven of the highlands of Ethiopia. <br><br>
| |
− | Crows have three toes that point forward and one that points backwards. The front middle toe curves inward and like the rear toe, is longer than the two on the side. The tracks are typically between {{units|5-8cm|2-3 inches}} long and {{units|10 cm|4 inches}} apart. Crows often drag their feet when they walk, so you may find the drag marks as part of the track. Their talons (claws) may also print. Their foot prints will alternate, as their gait is somewhat human-like.

| |
| | | |
− | These birds feed mainly on vegetation, but also on insects, especially when feeding young. Several of the forest-living species are notable for eating large quantities of conifer needles, which most other vertebrates refuse. In all but one species (the Willow Grouse, called Willow Ptarmigan in America), males are polygamous, and many species have elaborate courtship displays. These heavily built birds have legs feathered to the toes.

Sometimes the fourth toe will print too, extending from the metatarsal print towards the back. Sometimes the claws will also print. If made in soft mud you may be able to make out the pebbly texture of the foot in the track.

− | ===Trailing and Identifying===
| |
− | This is a perfect activity for an afternoon hike during a campout. Bring a tape measure so that you can measure the tracks. Bring some powdered plaster of Paris, and a mixing bowl so that you can make casts. You can also bring water, though it is better to keep that for ''drinking'' rather than mixing with plaster. You can probably find some water along the way, but just to make sure, you should bring ''some'' water for the plaster. You can refill a bottle for plaster making without treating it as long as you make it obvious that it is not fit for drinking (mud is a good indicator).
| |
| | | |
− | Instruct your Pathfinders that they are to look for animal tracks along the way. When they find some (or when you do), try to figure out the species by comparing the track to those in a field guide or those depicted in the answers to requirement one. See if you can find more tracks nearby. Which way was the animal moving? How far can you track it?
| + | {{clear}} |
| | | |
− | ===Walking vs Running===
| + | {{clear}} |
− | If the tracks are far apart relative to the size of the animal, it was most likely running. Another indicator of running is that the tracks are deeper than those made by a walking creature (running makes the feet strike the ground with greater force).
| |
− | ===Measuring Tracks===
| |
− | There is nothing in this requirement to suggest that the tracks of one animal made while running and walking has to be a wild animal, or even that you have to find a set of tracks like these pre-made. If you or a person in your group, or a person you know has a dog, take it to a sandy area and have it walk and run. Then get a tape measure and determine the distance between the tracks.
| |
| | | |
− | You can also do this in a parking lot, but in order for the dog to leave tracks, you will need to dip its feet in tempera paint (which is non-toxic and water soluble). It is best to pour some paint in a paper plate. Use two colors - one for the front feet, and one for the back. This will make it a lot easier to tell the front prints from the hind. Lift the dog, and have a helper wet the dog's pads. Then put the dog down and walk it (use a leash). Re-apply the paint, and then allow the dog to run. You should now have two sets of prints from a single animal. Get out a tape measure, and take the measurements.
| + | {{clear}} |
| | | |
− | The standard way to do this is to measure the distance between tracks made by the same foot. The distance between the left rear and the right front is almost meaningless.

− | Do not select a space ''too'' close to your campsite, because you do not want to attract them into your camp. Animals need water, so a really good place to select is around a source of fresh water. River banks, stream banks, near ponds, and the shores of lakes are all good places to find animal tracks. Pigeons often congregate under bridges or parking garages, so that is another good option. However, the place you select must be quiet. Avoid places that are frequented by people.

− | There may already be some tracks in the area, but you are interested in fresh tracks. Smoothing the ground erases them and allows for fresh prints. A mason's trowel works very well for this in mud. You can also use a trowel on sand, but be careful not to pack it down. The smoother you can make the surface, the finer tracks you will be able to see.
| |
| | | |
− | For dirt, it helps if you can sift it onto a flat surface and then lightly wet it. If your garden hose has a "mist" setting, use that after sifting the dirt onto a flat surface.

− | Some animals can become dangerous if they become habituated to acquiring food from human sources. This is especially true of bears. When this happens, it is often futile to attempt to relocate the animal, as they are very clever and can (and do!) find their way back to their home range. The only way to keep the public safe under these conditions is to destroy the animal. A common saying among wildlife control officers is "a fed bear is a dead bear."
| + | {{clear}} |
| | | |
− | Furthermore, relocating the animal puts it in a new environment where it does not know where to find the resources it needs to survive, so it may suffer greatly while it adapts, or it may fail to adapt and starve to death.
| + | {{clear}} |
| | | |
− | Many animals are also territorial, so relocating an animal may put it in conflict with members of its own species. They will attempt to drive the newcomer off, or may even kill it.

− | When camping, remember to store your food in a place where the animals cannot get to it. Seal it tightly and place it out of the reach of raccoons and bears (both of which are very clever at getting food). Under no circumstances should you store food in a tent - especially in one that people will be sleeping in. A tent poses no barrier to a hungry skunk.

− | The morning is the best time to check for tracks. Most forest creatures are nocturnal, so in the morning the tracks will be freshest. Also, human visitors are less likely to trample the tracks before you get a chance to observe and if necessary, cast them.
| + | {{clear}} |
| | | |
− | If you wish to photograph your tracks, it's best to do that in the early morning when the sunlight comes in at an angle. If you wait until the sun is high overhead, the track will not cast a shadow and it will be difficult to see. Turn off your camera's flash or it will completely wash out the shadows and the track will not show up in the photo. If you want to experiment with artificial light, use a flashlight to illuminate the track from the side. Place a coin or a ruler (for scale) next to the track before taking the picture. Take lots of photos (digital cameras are ''great'' for this) and hope that at least one of them turns out. It takes a lot of practice!

− | Animals leave many indications that they were present. These are collectively called ''sign''. Sign includes:
| |
− | ;Tracks: Not only footprints, but marks left on the ground by the tail or by other body parts. Beavers, muskrats, mice, and rats all leave tail marks on the ground.
| |
− | ;Scat: Scat is another word for animal droppings or manure.
| |
− | ;Fur and antlers: Animals may leave bits of fur behind if it gets caught in a tree's bark, or in thorns. In the fall deer drop antlers.
| |
− | ;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. Porcupines will eat the bark all the way around the trunk of a conifer, often killing it.
| |
− | ;Damage to trees: beavers especially, but also other animals will damage trees by breaking branches, chewing twigs, and gnawing bark.
| |
− | ;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: Once a predator has had its fill of a kill, it will leave the carcass. Some animals will guard their carcasses though so they can feed on them again after they've digested some of the previous meal, so be careful if you find one.

− | ===Rabbit vs Squirrel Tracks===
| |
− | Rabbits leave a distinctive pattern when they bound along. The front feet are thrown between the hind feet, but one of them is almost invariably thrown farther back, and the two forefeet often print one behind the other (though sometimes they print side-by-side). A rabbit's hind feet leave larger oval-shaped prints about the size of a man's thumbprint. Since they use the hind feet rather than their forefeet to leap forward, they will push out some material behind them. It may be difficult to make out individual toes in a rabbit print.
| |
| | | |
− | Squirrels are also bounders, and like the rabbit, they throw both forefeet between their hind feet. But unlike the rabbit, the squirrel's forefeet generally print side-by-side. The hind feet should print five toes (four finger-like and one thumb-like) and no claws. The forefeet should print only four toes.
| + | {{clear}} |
| | | |
− | In general, a rabbit's pads are shaped like an oval while a squirrel's pads are shaped like a human hand.
| + | {{clear}} |
| | | |
− | If you're lucky enough to find a large set of tracks in the snow, and they lead to the base of a tree, it is almost certainly a squirrel, as rabbits cannot climb trees. The only way a rabbit could leave such a trail is if it had been abducted by aliens (or by an owl!)
| + | {{clear}} |
| | | |
− | ===Dog vs Cat Tracks===
| + | {{clear}} |
− | Unlike dogs, cats can retract their claws, and they do so when walking. Therefore, you should expect to find claw marks present in dog tracks, but absent in cat tracks. In general dogs tracks are larger than cat tracks, but you cannot rely on this alone, as there are some very small dogs and some very large cats.

Then they digest the soft portions (such as meat) leaving the hair and bones behind to collect into pellets. They cough up these pellets which can be found by the astute observer.

− | Tracks for these animals are described in an earlier requirement. Perhaps the easiest of these three to find are the tracks of the frog. Find a pond where frogs live, and smooth the mud as described in requirement 4. Another technique is to visit a frog pond and watch as they leap into the water at your approach. Look carefully at the spot from which they leap, and you may be able to see the track. If you have any Pathfinders brave enough, have one capture a frog, and then gently transport it to a muddy area where it can leave tracks. Put it in the center of this area and observe the tracks it makes. Recapture the frog and return it to its home when you are finished.

− | When most people think of mollusks, they think of clams and mussels. For this honor, it is beneficial to remember that snails and slugs are also members of the mollusk family, especially since they leave easily followed trails.
| |
| | | |
− | The best time to find snail or slug tracks is in the early morning. Look on the sidewalk near flower beds for the tell-tale slimy trails these creatures leave as they slip along. As these slime trails dry, they turn white and flaky, often curling at the edges.

− | Find a place where you have seen earthworms in the past, preferably where the dirt is bare (i.e., no grass). Soak the area with water to drive the worms out of the ground. Worms need air, so when it rains (or when a Pathfinder soaks the ground with a hose), they will come to the surface. They might not come out immediately, so you should plan to return a day later to look for tracks in the mud you've made.
