Vegetarian Eagle Evolution

These birds have astonished scientists with an ability to apply complex social reasoning, incredible feats of memory, and an outstanding aptitude for crafting and using tools.

The second reason why the bald eagles became an endangered species is hunting. Before the bald eagle was declared an endangered species, they were hunted as any other animal was. Despite being the symbol of the nation, the eagles were still considered a nuisance and were shot on sight. This ignorance brought the bald eagle closer to becoming an endangered species.

Here is some of the biology of the Bald Eagle. Bald Eagles do a very good job at their part in the food web. Bald eagles also have an interesting name. The scientific name for bald eagles is Haliaeetus leucocephalus. The family order is accipitridae and falconiformes.

There are numerous counts of evidence showing the processes of evolution and how species ultimately evolved over millions of years. One of the most compelling hypotheses behind evolution was presented by Charles Darwin with his study of the Galapagos Islands. His study showing the various different birds and their different evolutions they went through to be able to survive the changes of weather and relocation. The birds he studied had to change in order to survive, or as he simply puts it: “Survival of the Fittest”. Evolution is the changing of past organisms to diversify and have the ability to fit better in their environment and survive. Diving into the dinosaur cladogram, studies have shown that ancient dinosaurs, over hundreds of millions of years ago, evolved into our modern day birds, and not lizards as many suppose. It became apparent that there would not be enough food for a 9 ton dinosaur to consume on a daily basis forever. So evolution occurred and dinosaurs evolved to become more efficient so they could survive more effectively in their

To compare the impact of evolution on different organisms a study was conducted by: carefully examining the species of birds with each other. This was accomplished through using a sample population of 200 birds. Moreover, there were other factors that were taken into account (in order to ensure objectivity and accuracy). The below table is illustrating those factors that were considered to be the most important during this study. ("Evolution Lab," 2012)

Ovid’s epic “The Essential Metamorphoses” and Ghandl’s poem “Goose food” present similar visions of women, and the writers show that men might not actually be superior, compared to women as they are often portrayed in myth. Moreover, in Ovid, there are numerous myths told, but in most of them, there is a recurrent theme of misogyny, and in the first myth of the epic – called “Origin of the World”–, on top of just describing the creation of the world, it is mentioned that man was first to be created and woman was made second. This could be because of numerous reasons; for example, Ovid could have been jealous that it was actually woman that was created first or maybe Ovid wanted to follow what the rest of society believed in order to be able to gain the trust of the readers so that he could then be able to put unrealistic views and that when reading the epic, the reader becomes skeptical of what seems so true to him at first and that maybe the whole principal of man being at the center of attention is not a true fact. Similarly, in Ghandl’s “Goose Food”, this story is told in a single way and man again is at the center of the attention, but this could be to give…(not good ). These stories portray women in a negative way in order to make readers realize that they are actually equal to men in real life and that they might even be superior to men. This statement can be viewed through the way women look physically, the actions they perform, how men interact in proximity to them

Bald eagles are birds of prey, mainly feeding on fish but they also may feed on other small birds. Eagles steal from other consumers quite often, attacking birds just to snatch a salmon from their talons. They also have been known to swoop down on otters to claim fish as the otters are eating it. An eagle's niche consists of praying and stealing food from the

One of its most important characteristics is its beak. The finch adapted to have a thin, long beak to probe through moss, bark and leaves in search of food (Wildscreen Arkive, N.D.). These finches have the thinnest beak out of the 13 finches; which aids them to find small insects. The Green Warbler finch are mostly found in humid highland forest where their primary food source is found. These adaptations made them more fit to survive on available food. Over the years the finch’s beak has evolved as the bird developed different taste for insects. Another famous adaptation is how they camouflage in their environment. The Green Warbler is restricted to the forest and is greener in body colouration, while the Gray Warbler is found in shrubby, dry thickets and is greyer and duller looking (Certhidea olivacea, 2010). Their coloration helps them camouflage in their own environments, and to hide from predators. Recent studies have found that there are in fact two separate species of the Warbler Finch, the Green Warbler Finch and the Grey Warbler Finch, but are considered as a single species (Wildscreen Arkive, N.D.). The Green Warbler finch mainly occupies larger, inner islands, while the Grey Warbler finch inhabits the smaller, outer islands (Green Warbler Finch,

For this week’s forum, I choose to talk about the bald eagle. The scientific name for the bald eagle is Haliaeetus leucocephalu and comes from the accipitrine family. With the bald eagle growing three feet tall had having a wing span of seven feet, this magnificent bird has few predator’s. Crow’s enjoy harassing the bald eagle, but pose very little threat. Animals such as the; great horned owl, squirrels, raccoons and ravens will try to snatch the eggs from the nest of the bald eagle. The one major predator of the bald eagle is humans, in the past farmers would kill eagles to protect their crops and livestock, bring the eagles almost into extinction. The bald eagle is no longer on the endangered species list, but it’s still illegal to

In 1977 a drought reduced the number of small seeds available for the birds, forcing them to rely on larger seeds and nuts, which were difficult for birds with smaller beaks to open. The number of birds unable to eat reduced as they died and gave way to harder beaked finches. Within a couple of generations they had evolved larger beaks. In 2003 another drought struck the Galapagos and as there were many large beaked finches, the food source of nuts dwindled, making the ability to eat smaller seeds an asset. The numbers of larger beaked birds dwindled as food became scarce, leaving the smaller birds to survive and reproduce. Darwin’s theory was not well received when first written in On the Origin of Species, though many scientists today use it as a basis for research in evolution.

Eagles have an external naris on both sides of their beak. An eagle's lungs and air sac system are adequate for its size.

Is your way of life unamerican? The bald eagle is one of the United States prized living organism and has been the national bird since 1783. However, in recent years these animals have been learning to cope with technological advances from humans. According to R. Russell and J. Franson the biggest causes of mortality in our nation’s bird is electrocution and trauma, poisoning, and disease.

Prior to the 1990’s the golden eagle didn’t exist on the channel islands probably because of the existence of the bald eagle on the islands ( they competed on the same habitats). The bald eagle prevented the golden eagle from nesting on the channel islands and unintentionally saved the lives of the island foxes. In the 1960s the pesticide DDT was introduced into farming and contaminated the fish that the bald eagle was feeding on, between the 1960’s to the 1990s bald eagles became endangered because of the pesticide. Bald eagles came to consume DDT because of how carelessly the humans used the pesticide, as a result the population of the Bald Eagle dropped dramatically. Ranchers from the mainland started bringing sheep and feral pigs to the

The pair of crowned eagles uses the same nest for a long time, until two new eagles inherit it. Their nest is made of sticks and twigs and lined with fresh branches. The eagles add new branches to the nest each year, and over time the nest can grow up to 7 feet across and 9 feet deep. It typically rests in about a 100 foot-tall tree. The female crowned eagle lays one or two eggs, which are white and speckled with a red-brown color. She incubates the eggs for about the next 50 days while her mate brings her food every 3 or 4 days. Sometimes they switch roles, the male incubating and the female hunting. When the chick (or chicks) hatches, it is covered in down feathers. the sad part is If there are two chicks, the stronger kills the weaker

The Jay Wolf is a mutation of a blue jay and a wolf. The Jay Wolf can run fast on the ground, smell danger from more than a mile away, and could fly. They were used as quick attacks on ground and air in small packs against the Capitol’s enemies.And they were used as trackers, guards, and as a search and rescue team. The Capitol created it to help save as much Capitol soldiers as they can.Their main goal was to be quick and unseen. The Blue Jay part of the Jay Wolf is different because the wings have a longer width span they fly for longer, faster, and they are stronger. The Wolf part of the Jay Wolf has bigger feet, a bigger leap, sharper senses and instincts, and they have more endurance and speed in running and flying.
