30 Amazing Facts about Beaver | Amazing Facts 4U

  1. Beavers are semi aquatic rodents usually found by streams, ponds, rivers and lakes.
  2. Beaver is the Canadian national animal and is depicted on the Canadian five cent piece.
  3. Beavers were plenty in England until they  were hunted to extinction in the 12th century.
  4. An adult beaver is approximately 3 feet long.
  5. Beaver has a thick brown fur coat and a soft grey undercoat that protects it from all climates.
  6. An adult beaver can weigh between 30 and 70 pounds. Female beavers are larger.
  7. The beaver can live 15 – 21 years in the wild and much longer in captivity.
  8. Beavers are nocturnal creatures working at night.
  9. Beavers are in fact the second largest rodents on earth. Their large front teeth never stop growing. The beavers constant gnawing on wood keeps their teeth from growing too long.
  10. Beavers are second only to humans in their ability to manipulate their environment mainly because of their amazing “dam construction projects”
  11. A stick-and-mud dam built across a stream at the edge of a lake can tell you a beaver is nearby.
  12. The beaver is an industrious creature and their dam building creates wetlands that support other wildlife. A beaver will fell a particular tree with their sharp teeth for a particular reason; a larger mature tree will be felled to form the basis of a dam. A young, second growth tree will be felled for food.
  13. As well as wetland, beavers create standing dead wood (by drowning some trees) which is inhabited by insects, and in turn attracts bird life.
  14. There are two species of beaver; the North American beaver and the European beaver. Although very similar in appearance and behaviour, the two species are totally incompatible. They have a different number of chromosomes and  they do not cross breed with one another.
  15. Beavers usually have one mate for life! The gestation period of beavers is 105 days.
  16. Baby beavers are called Kits. Once a beaver is two-years-old, it leaves the family. It reaches sexual maturity by 3 years.
  17. Beavers are territorial. They mark and protect their space.
  18. Beavers have poor sight but a strong sense of smell and good hearing.
  19. Beavers are herbivores. They feed on trees and tree bark; common favorites are cherry, maple, birch and aspens. Beavers also feed on water lilies, pondweed and leaves.
  20. A common belief about beavers is that they eat wood, when in fact it’s only the bark they eat.
  21. Beavers move slow on land but are good swimmers and can swim up to 5 mph. Beavers can stay underwater for up to 15 minutes.
  22. Beavers homes, called lodges, are domelike constructions built from branches and mud. They are positioned in open water for protection from predators and have underwater entrance holes leading to the main living chamber.
  23. Their lodges typically contain two dens, one for drying off after entering the lodge under water, and a second, dryer den where the family will live and socialize. Beavers do not hibernate and lodges need to be built in deep enough water so the entrance does not freeze in the winter.
  24. Their ears and noses have valves that they can close before submerging themselves under water.
  25. Their front teeth stick out of their closed mouths so that they may work underwater without swallowing water. When they fell a tree they waste nothing, systematically eating the bark and buds before cutting up branches and sections of the trunk to carry for use in dams or lodges.
  26. They use these dams as protection from predators and as shelter throughout the winter. If a predator destroys part of the dam, it will be fixed overnight.
  27. They are amazing lone engineers and generally work independently with little contact with each other.
  28. What is believed to be the world’s largest beaver dam has been built in Wood Buffalo National Park in northern Alberta , Canada. It is an 850-metre long beaver dam . It is located about 190 kilometres northeast of Fort McMurray, AB. Beavers are the only creatures on earth, other than humans, that build structures visible from space.
  29. Beavers possess a set of transparent eyelids which enable them to see under water.
  30. A beaver’s broad stiff tail about a foot long is a little like a Swiss Army knife: it is used as a rudder to steer under water , a third leg while standing upright, as a lever to drag branches and can be slapped on the water to warn other beavers of danger.
