Which animals eat beavers

As horrible as it sounds, it remains that humans are the greatest threat to the North American beaver. Both black and brown bears will hunt beavers if hungry and given a chance. This fact is true for humans, and unfortunately, beavers. Though beavers spend a lot of time in the water, they often fall prey to big cats like Mountain Lions, Lynx, and Bobcats! Owls can easily pick off a small beaver, especially babies. Depending on its size, there are few things that birds of prey fear going after.

Beavers tend to blend in with their surroundings, but birds like eagles and hawks have the advantage of a good vantage point and incredible eyesight. Birds of prey, especially in the mountains, grow large and robust if healthy.

Details on North American Beavers and Predators Predation is especially prevalent in the youngsters, as they are physically much smaller and therefore easier to attack than their fully grown counterparts.

Details on Eurasian Beavers and Predators As with North American beavers, Eurasian beavers often can stay safe and sound away from menacing predators simply by remaining inside their sturdy, well-crafted lodges.

North American beavers are the largest rodents in North America and the second largest in the world South America's capybaras being the heaviest.

They weigh between 35 and 65 pounds 16 to 30 kilograms , with the heaviest beaver on record weighing pounds 50 kilograms. They are 3 to 4 feet 1 to 1. The shape of the beaver's tail varies but, in general, is about 2 inches 5 centimeters thick at the base and tapers to about 0.

Beavers are found throughout North America with the exception of the California and Nevada deserts and parts of Utah and Arizona. They live in ponds, lakes, rivers, marshes, streams and adjacent wetland areas.

Beavers are one of the few animals that modify their habitat; they build watertight dams of sticks woven with reeds, branches and saplings, which are caulked with mud.

Dams reduce stream erosion by forming slow-moving ponds. These ponds serve as habitat for a wide range of small aquatic life and also provide water and food for much larger animals. By building dams, beavers create new habitats that can support an incredibly diverse biological community. Beavers also build dome-like lodges that rise 6. A lodge can have one or more underwater entrances and living quarters are located in the top of the lodge above the water line.

Often built away from the shore, these lodges form islands that can only be entered from underwater. The lodge chamber may be 4 feet 1. Beavers spend the summer and fall building dams and gathering and storing food for the winter. One important communication signal among beavers is a tail slap on the surface of the water, indicating danger.

Typically performed by an adult, this alarm signal alerts others in the area to seek refuge in deep water.

It may also frighten a predator. Beavers communicate outside of their family unit by depositing scents around the edges of their territory. The beaver is unique among rodents in that it builds scent mounds — heaps of mud, sticks and grass up to one-third of a meter high and about a meter wide on which they deposit scents from their anal glands. Beavers have important castor and oil glands near the anus. Castor, a very pungent, thick liquid, is produced for scent marking and leaves a long-lasting odor.

The oil glands produce the oil used to waterproof a beaver's fur. The oil is slightly different between the sexes and is used in reproductive communication. Within the lodge, beavers employ various vocalizations though their voice box is rudimentary and postures to communicate with family members. At the Smithsonian's National Zoo, beavers have occasionally been heard hissing if they are unhappy. Beavers are herbivores, eating leaves, woody stems and aquatic plants.

Their chief building materials are also their preferred foods: poplar, aspen, willow, birch and maple. In cold climates, they spend the winter inside their lodge chamber, feeding on branches they have stored on the muddy pond floor as a winter food supply. The water acts as a refrigerator, keeping the stems cold and preserving the nutritional value.

Beavers hold their food with their front paws, eating corn-on-the-cob style. They breed in February and gestation takes about days 4 months. They only produce one litter per year which consists of an average of three kits.

Females can begin breeding at 32 months about three years. Kits leave the colony at 2 years of age. Average weight for an adult beaver is 40 — 60 lbs 18 — 27 kg.
