Bald Eagle Scientific Name: Haliaeetus leucocephalus Bald Eagles are the national bird of the United States. They can grow to be 30-43 inches and have a wingspan of 6-8 feet. Their distinct white head and tail allow spectators to determine which type of bird it is from a distance. Preferred Habitat: 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.

eats a variety of smaller birds and fish. In certain circumstances these animals will also act as scavengers and eat roadkill. How it Modifies the Abiotic Environment: Bald Eagles modify their abiotic environment in many roundabout ways. One of these includes nesting. They often use human trash such as string, straws, or paper to help them build a nest. They also regurgitate some of their food in the form of pellets, much like owls. These pellets are left around wherever the animal last ate or is currently living. Native Range of a Bald Eagle: The following information is a key to what the colors on the map correspond to. Pink= Uncommon breeding areas of all seasons Dark Purple= Where the bird can be found in all seasons Light Purple= Uncommon places to find the bird in all seasons Blue= Uncommon places to find the bird in the winter season Symbiotic Relationships: A symbiotic relationship can be a series of different interactions between two or more different species. Such relationships include predation, commensalism, mutualism, and parasitism. Predation: one organism consumes another Commensalism: one organism is benefitted by the interaction and the other is neither harmed nor benefitted Mutualism: both organisms are benefitted by the interaction Parasitism: one organism uses another as a host site to obtain energy, the host organism is harmed Parasitism in Bald Eagles Helminth parasites are often found living on bald eagles presenting a parasitic relationship.
A Bald Eagle Ecology article states that Helminth parasites live on bald eagles to receive nourishment while disrupting nutrient absorption. The following photo shows an enlarged image of a Helminth parasite. Commensalism in Bald Eagles Bald eagles create nests in a variety of trees, according to an article on symbiosis on Weebly, one of the most popular trees that they nest in is a Acacia tree. This is a commensalistic relationship because the bird benefits by having a location to live and the tree is neither harmed nor benefitted by the nest on it. Mutualism in Bald Eagles Mutualistic relationships occur between eagles and farmers when farmers begin to plant crops in their fields. When crops are planted, prey are attracted to the field to eat. Bald eagles will surround fields to prepare to eat the prey that come in. The eagle will eat the prey that are coming into the field benefiting it by providing energy to the bird, and the farmer benefits because his crops are protected and have the ability to
grow. Predation in Bald Eagles: A bald eagle can eat a snake to obtain energy and nutrients from it. The eagle is the predator and the snake is the prey. This relationship represents predation.

The Pacific Northwest is perhaps most commonly known for its awe-inspiring old growth forests that have been gracing the land for hundreds and hundreds of years. The land in British Colombia, Canada, Washington state, Oregon, and parts of Northern California are the only areas in the world where these forests exist. One of the most unique and amazing inhabitants of this age-old forest is the Northern Spotted Owl. The Northern Spotted Owl has been on the endangered species list for over ten years now. The Northern Spotted Owl can only be found in these old growth forests. The northern spotted owl requires many acres old forests to survive, due to its scarce food supply. They are very sensitive to their habitat, and simply cannot survive in any other environment. These owls, as well as the forests have been disappearing at an alarming rate due to the immense logging industry in its area.
In 1927, Charles Elton took niche theory a step further and included food. He defined the niche of an animal as its place in the biotic environment and its relations to food and enemies (Elton, 1927). Grinnell also wondered if food was a limiting factor to the California Thrasher’s niche, but since the bird is omnivorous, it could find food in other habitats such as a forest floor or a meadow. There had to be other factors that restricted the bird to the chaparral bushes (Grinnel, 1917). Elton believes that the niche of an animal can be defined by its size and its food habits. It is important to study niches because it enables ecologists to see how different animal communities may resemble each other in the essentials of organization (Elton, 1927). For example, in a forest there could be a niche of owls that feeds on small animals such as rats. This same carnivore niche is filled with kestrels in the open grasslands. This carnivore niche is then dependent on the small animals in the herbivore niche (Elton, 1927). Hutchinson also discusses niche theory in his “Concluding Remarks” paper. His theory seems to combine some of the ideas
One of them is called a parasitic relationship this is when the tapeworm is benefited by eating the Red Pandas food but, the Red panda is hurt by the tapeworm eating all of its food. Another Symbiotic relationship is called a Commensalistic relationship this is when the red panda is benefited by getting protection from a tree while the tree is unaffected. The last relationship is the mutualistic relationship this is when the Red panda gets help from say a raccoon the raccoon bumps a bird’s nest down the Red panda eats the bird the racoon eats the eggs both are benefited. The Red panda has a variety of relationships but how does the Red panda do with the the harsh conditions of its
Rhetor’s since the days of Aristotle and Isocrates have been using their rhetorical situations to deliver messages with a sense of urgency and persuade others to see their point of view. In 1933, Luther Standing Bear published his book “Land of the Spotted Eagle”. In this book, he talks about the terrible conditions under which his people live and how it needs to change. He speaks specifically to this in the excerpt “What the Indian Means to America”. Here he is referencing the Great Depression and the Dust Bowl. Standing Bear talks about how the European Americans caused these disasters and how the Native American could be the solution to these problems. He uses his rhetorical situation to try and convince the American government to listen
They use their large wings to fly around and spot carcasses below. “There are about 435 California condors in the world today, in which 237 are living in the southwestern part of California. They live in California, Arizona, and Baja California, Mexico.” (Defenders of Wildlife, 2013) They’re as north as Big Sur to Ventura County and as east as the Sierra Nevada Mountain range, with other populations inhabiting the Grand Canyon in Arizona.
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.

White-tailed deer, also known as the whitetail, is native to the United States, Canada, Mexico, Central America, and South America as far south as Peru and Bolivia. What are the things called antlers and what are they made of? Deer antlers are made of bone. They grow from pedicles, bony bumps found on the heads of all deer, and they drop off after the mating season ends.
It's been an interesting last.. Hmm? 40 years I would say, for the Sea Otter. Sea otters, are a
“‘Farewell,’ they cried, ‘Wherever you fare till your eyries receive you at the journey 's end!’ That is the polite thing to say among Eagles. ‘May the wind under your wings bear you where the sun sails and the moon walks,’ answered Gandalf, who knew the correct reply.” (J.R.R. Tolkien, The Hobbit, or There and Back Again) For those reading this who are familiar with Lord of the Rings, one has heard the classic “Eagles theory.” This theory states that before Gandalf died, he had planned for the Fellowship to take the Eagles to Mordor, and when he came back as Gandalf the White he had forgotten about it (Covucci “A Thorough Rebuttal to the ‘Why Didn’t the Eagles Just Fly Frodo to Mordor’ LOTR Complaint”) While this theory makes sense for those
American Crows (Corvus brachyrhynchos) are a species of bird found in the family Corvidae, a family that also includes magpies, nutcrackers, and jays (Eastman, 1997). According to Eastman’s book Birds of Forest, Yard, and Thicket, there are around forty-two Corvus species, and most of them live in the Northern Hemisphere (1997). American Crows in the United States usually do not migrate, but they do migrate to Canada. Not all American Crows migrate, but they are social birds who form wintertime flocks that sometimes reach over 200,000 birds (Burton et al., 2010). American Crows have a number of features that make them identifiable, and to help keep them from being confused with another member of the Corvus genus, the Common Raven (Marzluff et al., 2013).
In North America the golden eagle occurs as far south as Mexico, but it is most common in the mountainous areas of the western United States and Canada; east of the Mississippi it is relatively rare. Females attain a length of about 1 m (about 3 ft) from the tip of the beak to the tip of the tail, and have a wingspread of about 2 m (about 7 ft). Males are smaller, as is true for most of the birds of prey. A characteristic of the genus is the feathering of the legs down to the toes; in other eagles the lower part of the leg is bare and scaled, as in most birds. The body plumage is dark brown, with a distinct golden wash over the back of the head and neck, giving the species its name. The tail of adults is brown with several indistinct pale bands; that of immature birds is white with a dark brown terminal band.
It lives throughout the U.S. and parts of Canada. You can probably find Bald Eagles near lakes, reservoirs, rivers, marshes, and coasts.The bald eagle has been the U.S. National bird since 1782, Bald eagles are one of many of the large birds native to North America, with a wingspan of about 7 feet (2 meters). (They are second in size to the native California condor and are almost the same size as the golden eagle.) a Bald Eagles length is around 30.4-36.4 inches, as its weight is about 6.6-13.9 lbs. Young bald eagles have mostly dark heads and tails, their brown wings and bodies are combined with white in varying amounts.
The hornbill has a casque on top of its head, giving it its name. The casque is made of the same material of the bill itself. It is a black bird with a white stomach. The bottom of the wings are white as well. It has white around its eyes. The bird is typically 55-60 cm long. The male is 680-907 g in weight. Those are just a few of the characteristics of the hornbill.
