Grizzly bears, also known as brown bears, are among the largest meat-eating mammals. They can be found in North America in areas like Alaska, Canada, and the Rocky Mountains of Montana and Wyoming. An adult grizzly can grow to be 8 feet long and weigh about 900 pounds! Because of their size, grizzlies rarely climb trees, but they can reach speeds of 30 miles per hour for short distances.
Grizzly bears are opportunistic omnivores. They will search for and eat berries, plant roots, leaves, and fish and will hunt small animals, rodents, and even large animals such as the moose. Grizzly bears are solitary hunters that can pose threats to humans. They can be particularly dangerous if scared, surprised, or perceive a threat to their young. During the end of summer through fall, grizzlies eat an extra amount of food to build up fat in their bodies. They build up this fat for their bodies to use and to keep warm during hibernation.

Black bears are the most common bears in the world, and are one of only two bear species not classified as threatened or endangered. Despite their name, not all black bears are black in color. Their color can range from whitish to black as well as all shades of brown in between. Male black bears weight between 150-550 pounds, though much larger specimens have been found, including one male that weighed over 1,100 pounds in New Brunswick, Canada. Females are smaller and typically weigh around 200 pounds. Black bears are highly omnivorous in diet. While they will eat deer, elk, and moose, the bulk of their diet consists of roots, insects, larvae, grass, and other plants. Because of their versatile diet, they can be found in a variety of areas in North America from Alaska to Mexico. Black bears that live near humans must often be re-located because they become accustomed to feasting on trash and can cause serious damage to homes and cars. |

Description
The Great Gray Owl is the largest owl found in North America . Measuring 28 inches in length, the "Gray Ghost" is actually mostly feathers and is lighter than many smaller owls. Adults weigh between 1/2 and four pounds. Females are heavier and larger than males. The Great Gray Owl is unmistakable, with a large head, conspicuous concentric rings around the face, small yellow eyes, large gray body, streaked gray underparts, small white bill, and long tail. It lacks ear tufts.
The Great Gray Owl does not build its own nest; rather, it takes over an old hawk or crow nest. Nesting occurs any time between March and May. The female typically lays four eggs, which are incubated from 4 to 5 weeks. Young owls fledge about three to four weeks after hatching and begin to fly one to two weeks later.
Diet
Small mammals such as mice, voles, and hares. It will occasionally take grouse and other small and medium-sized birds. The Great Gray Owl hunts at night and takes it prey upon silent wings. Like all owls, the Great Gray has specially adapted feathers that allow for silent flight. Owl victims cannot hear the flapping of wings. The Great Gray Owl has superb hearing and can detect movement beneath two feet of snow.
Range and Habitat
The Great Gray Owl breeds across the taiga belt in the Northern Hemisphere. In North America, the owl breeds from northern Canada and Alaska, south to the Great Lakes region and northern parts of the mountain west (such as Yellowstone National Park). In winter, some birds may be found farther south. Great Gray Owls prefer thick coniferous and mixed forests, especially near swamps or bogs.
Status
The Great Gray Owl is uncommon, though populations are thought to be stable. Clear-cutting of boreal forests has a negative impact on these birds.
Northern Goshawk

The beaver, known for its distinctive flat tail and gnawing abilities, is one of the largest rodents in North America. With a lifespan of up to 20 years in the wild, these semi-aquatic mammals are known for their engineering skills and their ability to transform the environment around them. Physical CharacteristicsBeavers have a distinctive appearance, with dense brown fur covering their large, stocky bodies. They have a broad, flat tail that they use for balance and communication, as well as powerful, chisel-like incisors that can cut through trees with ease. Beavers can grow to be up to four feet long and can weigh up to 70 pounds, making them some of the largest rodents in the world. Habitat and DistributionBeavers are native to North America, but they can also be found in Europe and Asia. They are typically found near bodies of water, such as rivers, lakes, and ponds, where they build their homes, called lodges or dams. These structures are made from sticks, mud, and rocks, and can be quite large, with some beaver dams measuring up to 2,700 feet in length. Ecological ImportanceBeavers play an important role in their ecosystem, as they are known for their engineering skills and their ability to transform the environment around them. By building dams and lodges, they create wetland habitats that support a wide variety of plant and animal life. These habitats also help to filter water, reducing sediment and pollutants and improving water quality. In addition to creating wetland habitats, beavers are also known for their ability to modify the landscape by cutting down trees and shrubs. While this behavior can sometimes be detrimental to human interests, such as flooding roads or damaging crops, it is an important part of the natural ecosystem. Beaver activity can create new habitats for other animals, such as birds and fish, and can also help to prevent erosion and promote the growth of new vegetation. Conservation StatusWhile beavers were once hunted extensively for their fur and meat, they are now protected in most areas of North America. In some cases, beavers have even been reintroduced to areas where they were once extinct, in order to help restore wetland habitats and promote ecological diversity. Despite their protected status, beavers still face threats from habitat destruction, pollution, and climate change. As such, it is important to continue to monitor beaver populations and take steps to protect their habitats and promote their conservation.
