People often disagree about the beaver. Some think this master dam builder is the smartest thing in fur pants, and they use such words as intelligent, energetic, and helpful when speaking of it. Others claim the paddle-tailed engineer is dumb, stubborn, and destructive. A look at the beaver and its lifestyle may show why opinions are so different.
No other creature besides humans controls its environment as completely as the beaver — changing the surroundings to meet its needs. The chubby beaver is slow and clumsy on land, waddling along at the mercy of its predators. However, in water it becomes a sleek, stream-lined swimmer that can travel at five or six miles an hour. No wonder the beaver chooses to surround itself with water and builds a dam to make sure there's Spokane rescue mission. Water provides protection as well as an easy way to travel.
As water backs up behind the dam, it brings the beaver's food supply within reach of the water. Raising the dam deepens the water and spreads it to new food sources as old ones are used. Going back in time a million years or so, we discover the beaver is the descendant of an pound prehistoric rodent.
Adult beavers, which average between 30 and 60 pounds, may seem rather puny by comparison, but they still rank as the second largest rodents in the world, right behind the South American capybara kap-ah-BARE-ah.
A record beaver found in weighed pounds, and heavyweights that tip the scales between 80 and pounds still are caught occasionally. The beaver has been described by some as a "furry hunk of homeliness. Its fur coat, which looks messy when wet and ungroomed, has an outer layer of long guard hairs that cover an inner layer of wooly underfur. The underfur is so thick and well oiled that water usually cannot reach the skin beneath it.
Those who have felt the beaver's fur underwater describe it as smooth and slippery. This slickness keeps water drag to a minimum as the animal swims. The dark chestnut brown of its winter fur may fade to a golden tan by spring. Frequent grooming is necessary to keep the fur tidy. Each hind foot has a split or double toenail that serves as a comb.
Drawing the hairs through these double nails removes excess water and straightens any tangles. Despite its large size, the beaver can twist and bend to reach every part of its wet fur with these toenail combs.
The toenails also serve as toothpicks to remove wood splinters left between its teeth. Once the fur is combed, it must be oiled. The beaver does not always sit on its tail during the combing process, but it cannot oil itself until it does. Sitting back with its tail folded under its body exposes the opening at the tail base in which the beaver's sex organs and its large oil glands are located. Using its front feet, the beaver reaches down, scoops up the strong-smelling oil released from the glands, and rubs Beaver spead wide on the fur.
The toenail combs then spread the oil evenly through the fur. This grooming process takes place right after the beaver leaves the water Escort big clit requires about ten or fifteen minutes to complete.
The yellowish oil, called castoreum, is also used by the beaver to mark its territory. Using its front feet, the beaver rakes together a mud patty, which often contains wood chips and other debris, and places it in a highly visible spot. It then soaks the patty with castoreum. Researchers have found that this oil contains at least forty-five chemical ingredients, and humans have used the oil in making perfumes. The scented patty reveals the sex of the beaver that made it and many other messages only another beaver Free virgin anal mpegs understand.
It serves as a chemical communication system. Although the water's surface seldom freezes around its lodge, the southern beaver still gathers and stores a cache of twigs and branches under water for winter food. The adult's tail is about a foot long, six or seven inches wide, and less than an inch thick.
The base is covered with the same type of fur as the body, but the flat, scaly part of the tail has only a few short, bristly hairs. The tail serves as a prop on dry land, bracing the beaver as it cuts down a tree and helping the beaver sit up so it can use its front feet for various chores. At any sign of danger the beaver slaps its flat tail on the water's surface with a loud smack, creating a big splash before it dives to safety. Some observers believe that slapping the tail in water and on land not only is a warning signal for fellow beavers, but also may be a sign of anger or an attempt to frighten away an approaching predator.
A downward thrust of the tail as the beaver submerges helps push its body under. Once underwater, the tail acts as a diving plane, determining the angle of descent. It also serves as a rudder, keeping the beaver on a straight course, especially when the animal is towing a tree or large branch. Seldom, if ever, is the tail used for actual swimming. Large, webbed hind feet deliver the powerful strokes that push the beaver through the water.
The webbing folds together ducklike as the foot is brought forward and spreads wide for the backward thrust. If the beaver is in no particular hurry, its back feet stroke at the same time, sending it forward in a smooth glide. As the forward movement slows, the feet stroke together again. But when the beaver needs to turn on the speed, it switches to alternate foot strokes.
Since each foot is six or seven inches long and spreads to a width of about six inches, each individual kick produces quite a bit of forward thrust. To further streamline its shape in the water, the beaver hugs its front legs to its chest. The front feet are clenched into fists and serve as bumpers.
Even though the beaver doesn't have thumbs, it has five fingers that are able to pick up and grip objects with ease. While the beaver is underwater, its heartbeat slows so less oxygen is needed. An extra large liver and big lungs make it possible for the beaver to store air and oxygen-rich blood for long dives.
Three minutes is the beaver's usual time underwater, but it can stay down for as long as fifteen minutes. It's not unusual for the beaver to travel as far as half a mile underwater before surfacing, especially if frightened.
The beaver has several waterproofing devices that go into operation as it submerges. Valves in the ears and nostrils snap shut and membranes slide over the eyes like goggles to protect them and increase their underwater vision. Folds of skin meet tightly behind the large front teeth to seal off the mouth.
These folds of skin also prevent splinters from entering the mouth as the beaver chomps away on land or in the water. Speaking of chomping, another unmistakable feature Beaver spead wide the beaver's large, orange Gay japense men. As with other rodents, these front teeth grow continually and are kept worn down by constant gnawing.
The front surface is very hard enamel that wears slowly. The backs are of a softer material that wears faster. This unequal wear gives the teeth a chisel-like edge, and the angle the edges form makes it possible for the beaver to sharpen them against each other. The sixteen molars used to grind the beaver's woody food seldom show any sign of wear. Small twigs are fed into the mouth with the front feet, nipped into small pieces by the front teeth, chewed by the molars, and swallowed.
When eating bark off larger sticks, the beaver picks up a piece about a foot long. One "hand" closes around it and the other grips it between the little finger and the other four. The stick is turned quickly and evenly by the fingers and moved slowly sideways.
The sharp front teeth strip off the bark as you might eat corn off a cob. When its mouth fills with bark, the beaver pauses, chews, swallows, Beaver spead wide its teeth, and then continues eating. Upon nearing the end, it holds the stick against the "palm" of its "hand" so the teeth can eat right up to the edge.
The cleaned stick is then tossed aside and another is picked up. Later these cleaned sticks will be used to reinforce the beaver's dam. A beaver dam is a remarkable structure, but the builder's reputation for engineering intelligence may be slightly exaggerated. In many cases a dam that would hold the same amount of water could have been built with only a fraction of the work if it had been placed either upstream or down-stream from the chosen site.
But whether the location seems ideal by human standards or not, once the Old women lesbos has been selected, the beaver stubbornly refuses to build elsewhere. Why the beaver chooses one site over another has puzzled people for years. This untidy pile of sticks is a beaver dam. It is remarkably strong and leak-proof as long as a beaver is using it and keeping it repaired. Beavers observers don't always agree on the way the dam is started.
One explanation for the different methods observed may be that beavers are adaptable. Some claim beavers cut down a tree so that it falls across a creek. Logs and branches are then floated downstream to catch in the fallen tree. According to Swedish researcher Lars Wilsson, who spent several years studying a beaver colony and experimenting with its residents, dam building is an instinctive action triggered by the sound of running water.
He discovered that when plenty of water is available, beavers may live in an area for some time without starting a dam. But if the water level drops low enough to ripple between or over some rocks or debris, the sound of the Vista wont find external hard drive, running water attracts the beavers and triggers a building urge. His captive beaver tried to build a dam in a bathtub full of water when a recording of running water was played beside the tub.
In the wild his beavers pushed or carried mud and rocks from the bottom of the stream to the low spot where the sound was occurring naturally. The low spot was built up with these materials until water no longer flowed over the top. The only problem was the water now flowed around either side of it, continuing to make the sound. This, too, had to be stopped, so the barrier was extended on each end. There is no mistaking the presence of a beaver in the neighborhood.
The distinctive work done by its powerful incisors gives it away.

The actions of beavers for hundreds of thousands of years  in the Northern Hemisphere have kept these watery systems healthy and in good repair. The North American beaver Castor canadensis , also called the Canadian beaver which is also the name of a subspecies , American beaver, or simply beaver in North America, is native to Canada, much of the United States and the states of Sonora and Chihuahua in northern Mexico. The " Lincoln Park beaver " has not been as well received by the Chicago Park District and the Lincoln Park Conservancy, which was concerned over damage to trees in the area. Beavers are able to enlarge their dams quickly. Bemrick Young from the previous year are about 22 months of age at this time and they are evicted from the colony to relocate and seek mates of their own. In the United States and Canada , the species is often referred to simply as "beaver", though this causes some confusion because another distantly related rodent, Aplodontia rufa , is often called the " mountain beaver ".
