Transcript

  • 1. THE BEAVER<br />
  • 2. The beaver lives near wooded streams. Beavers are found in a lot of parts in Canada<br />Where is the beaver live?<br />
  • 3. This creature is considered as A professional engineer and A hard worker at the same time that it makes its nest and establishes A dam to prevent water from destroying it<br />It spends a super effort to finish its job in a several stages. <br />it collects a huge amount of tree branches for its food and to build its home and dam. <br />The Beaver's Nest<br />For this purpose it gnaws the surrounding trees .<br />scientific searches proved that it makes great calculations to choose which branches it needs and which would be suitable for its project and also it was proven that it prefer to work on the river's banks to make the water help him in collecting the branches which it already cut.<br />
  • 4. The beaver builds a home (lodge) made of mud and branches. <br />The inside of the beaver's home is distinguished by a fabulous design with Tow underwater passages, a feeding area above the sea level and a dry area above it for the nest in addition to a fresh air hole at the top (roof) of the lodge. <br />Beaver also make a food store under the nest to be fed from along the winter season and make another passages net-like in shape to lead him to the land and the trees which is its food<br />most lodges are about 5 meters wide and 2 meters high<br />
  • 5. Mud is plastered on the outside of the lodge to make it strong<br />Beaver gather branches with each other to form the outside structure carefully using small branches and mud in order not to leave any holes or gaps in it.<br />This prevents enemies from breaking in. <br />The mud also helps keep the inside warm during the winter although it's too cold in winters up to -35 C degree it keeps the temperature warm inside above zero C all the time <br />
  • 6. Beavers may also build dens or burrows along river banks. <br />Sometimes they live in these bank burrows while they are building their lodge to hide from enemies.<br />It also builds a dam which is made of branches, mud and rocks by gathering them above each other the same way like it builds its nest. <br />This dam holds back the water and a deep pond is formed. The pond must be deep enough so water will not freeze to the bottom<br />
  • 7. The beaver is the largest rodent in North America. A full grown beaver can weigh from 16 to 32 kg. It can be from 60 to 80 cm. in length. Beavers have long sharp front teeth.<br />A beaver's tail is flat (about 30 cm. long) and covered with scales. The beaver uses the tail to steer when swimming or for balance when sitting on land. If an enemy is near, the beaver slaps its tail on the water to warn other beavers. The tail is not used to plaster mud on dams or lodges. <br />Appearance<br />
  • 8. The beaver's legs are short. It is not able to move quickly on land. But the beaver is a strong swimmer under water and on the surface of the water. <br />The front feet have sharp claws. The beaver uses the claws for digging up mud and stones. The beaver uses its front feet for carrying mud and branches. With its back feet the beaver spreads waterproofing oil on its fur. The beaver's fur has to be oily to keep the animal waterproof. <br />
  • 9. Food<br />Beavers eat the bark and leaves of trees. Their favorite tree is the aspen. Beavers also eat grasses, berries and water plants. <br />
  • 10. The beaver is well adapted for swimming. It can see well under water over its small eyes. The beaver's nostrils and ears can be closed when swimming. <br />Adaptations<br />The front teeth are very strong and sharp for gnawing and cutting down trees. Beavers pull smaller branches with their teeth. Bigger logs are rolled down to the pond with their front paws or their nose or the top of their heads.<br />
  • 11. Beavers mate for life. Early in the summer (May or June) the female has a litter of three or four kits.<br />The newborn have fur, teeth and can see and walk. The babies remain inside for about a month.<br />Beaver’s Family<br />The yearlings act as babysitters for the new litter. During their second year, young beavers help their parents repair the dam and lodge and gather food for winter.<br />Young beavers stay with their parents until they are two years old. <br />
  • 12. Wolves, coyotes, bears, and lynx are the enemies of the beaver. <br />Beavers can be easily caught when they are on land. <br />Enemies <br />River otters have been known to slip into the lodge and kill the kits. <br />In the winter when the water is frozen, predators can walk right up to the lodge. These animals may try to break into the lodge.<br />
