Name: Golden Eagle
Biome: Golden Eagles are commonly found in the temperate grasslands, savannas and shrub land, coniferous forest, and desert all year round. They are found in the boreal forest, and tundra during their breeding season in the summer, and the temperate broad leaf and mixed forest, coniferous forest and grasslands during the winter.
Habitat: Partially or completely open country, around mountains, hills, and cliffs. They use many different habitats ranging from arctic to desert, some include tundra, shrub lands, grasslands, coniferous forest, farmland and rivers or streams. They can be found in Mexico, North America, Alaska, and sometimes Asia, northern Africa, and Europe. They nest in high places such as cliffs, trees, or human structures. They build huge nests that they may return to for several breeding years.
Interacts with each of the 4 Spheres:
Atmosphere: The atmosphere affects the temperature and wind which are both things that are a large concern for the Golden Eagle. The temperature and the change between cold winter months and warm summer months changes wh...
The bald eagles can be found anywhere across the U.S and Canada. They can typically be found along rivers, coasts, lakes, in mountains, and in the open country. The availability of food in the area that the eagle is currently living in determines whether or not it will migrate during the winter months.
The Northern Spotted Owl can only live in old growth environment, it is considered an “indicator species”: The health of the Northern Spotted Owl population indicates the health of the old-growth forest ecosystem. An individual Northern Spotted Owl needs more than 3,000 acres of old growth to survive, because of its scarce food supply. The Northern Spotted Owl is found in the cool, moist woodlands on the Pacific Northwest. The habitat of the Northern Spotted Owl can be described as trees relatively large in diameter in the stand, multi-layered canopy, large tall live trees with cavities, broken tops, mistletoe, or platforms of branches capable of holding accumulated organic matter suitable for use as a nest, dead standing trees and fallen decayed trees to support abundant populations of prey species, especially northern flying squirrels and woodrats.

In 1782, the bald eagle was elected as the national symbol of the United States of America, yet by the early 1960’s, it was nearly extinct in the Continental United States. A combination of many dangers, with the main danger being the pesticide DDT, the bald eagle was on the verge of extinction. Yet, through conservation measure applied by the United States government the bald eagle cam back from the brink and was taken off of the endangered species list in 2007.
While driving On Rte10 through the town of Hamden what seems to be an ordinary ride can become a scenic view of our nation’s bird. On a tall skinny Birch tree over 40 ft in the air is lives a bald eagle in its natural habitat. In this nest lives a male adult and female adult with an Eaglet. The nest is located in a farming open field along a river bank. This field and river provides the eagles with a source of food. The eagles mostly eat fish, the adult eagle will swoop down to the water and grab a fish all in one motion flying the meal back to the nest to feed its family. The field is posted to prevent people from ruining the habitat, since the natural reproduction of this eagle is very important to its recovery from being endangered. I was able to view this community form the road and was able to watch the nest and occasionally watch the adult eagle fly away most likely looking for food to feed his family. The nest form my view was huge at least 3 feet in diameter perched up about 40 ft high on a birch tree. The surrounding area of the nest was clear of any branches or trees creating a clear access way for the birds to land. Below the nest was a large open field on the bank of an active river.
The habitat of the Arctic wolf is a very harsh place. The temperature must be below zero degrees. There are tundra, rolling hills, glacier valleys, ice fields, shallow lakes, and green flatlands (Arctic/Antarctic: The Arctic Wolf). These snowy white creators don’t have that many places to live. Arctic wolves used to be everywhere in North America, but sadly now they are reduced to Canada, Alaska, Idaho, Michigan, Minnesota, Montana, Wisconsin, and Wyoming (Arctic/Antarctic: The Arctic Wolf). Arctic wolves are one of the most dangerous types of wolves; people need to find a way to save them and their habitat before they disappear forever.
Barred owls tend to favor dense forests with large trees for nesting and allow for a relatively open under story. The owls use this under story to stalk and catch their prey from high above. The availability of perch sites and large trees for nesting have been found to be the most important factors in habitat selection. The Barred Owl can live in a variety of habitats including urban areas, swamps, oak savannas, marshes, and forests located next to fields that provide prey animals (Dark, Gutierrez, and Gordon, 1998).
Throughout this book, we will discuss the lifestyles and habitats of these three species as these are the most common in human surroundings.
Some birds in the eagle community are African fish eagle, Stellerís sea eagle, white-bellied sea eagle and the palm-nut vulture. Bald eagles, out of all eagles are carnivores; they eat fish, there is no such thing as a herbivore or even an omnivore Eagle. The young of a bald eagle are fully fledged (just like their parents and ready to live in the world) at about the age of 4 months. After hatching, newborn eagles are all white and blind.
The eastern gray squirrel live in various habitats all over the world, from woodlands, suburban, and urban areas, and they are most commonly found in North America. They also live in regions in Europe such as England and Scotland. The eastern gray squirrels lives in nests and dens; nests, made up a combination of sticks and leaves, are situated

Long-tailed weasel can live in a lot of different habitat types. In Maryland marshland, in the woods, grasslands and rocky places in Maryland are all long-tailed weasel habitats. The long-tailed weasel also lives in open areas covered with brush or tall grass near the water. Weasels live in dens made from hollow logs, tree stumps, rock piles or in burrows that it has taken over by killing the animals that use to live in the burrow.
States and southern Canada. In the west, the species was found from Mexico to California.
Their nest was an abandoned hawk's nest, high in a tree. It was made of sticks, twigs, and lined in bark. It had a spongy bed made from corn cobs. It was extremely comfortable, strong and much larger than they needed.
They Hyena mostly live in Africa, south of the Sahara, but except in the Congo Basin. Also large numbers of Hyenas live in Ethiopia, British Somalialand, and Ngrongoro Crater. Their habitat is usually a flat grassland. It is mostly dry and sometimes rocky area. There are few trees or plants. Mostly there are shrubs. There are also some mountains in the region.
