Bald eagles are found in many environments in the United States. Those environments include deserts, mountains, freshwater, and marine areas. Bald eagles are known to build very large nests in treetops and always near water. The main source of food for bald eagles is fish, but they will sometimes eat other small animals.
In the 1900s the population decreased because of the DDT ( DDT: dichlorodiphenyltrichloroethane) sickness with the eagles. Hunters are a treat to bald eagles because they will shoot them out of the sky. If a bald eagle eats a duck that has been eating lead shots that
How do hunters help the population? Several natural predators of white-tailed deer occur. Wolves, cougars, American alligators, jaguars, and humans are the most effective natural predators of white-tailed deer. These predators frequently pick out easily caught young or infirm deer, but can and do take healthy adults of any size. Bobcats, Canada lynx, bears, wolverines, and packs of coyotes usually prey mainly on fawns. Bears may sometimes attack adult deer, while lynxes, coyotes, and wolverines are most likely to take adult deer when the ungulates are weakened by harsh winter weather. Many scavengers rely on deer as carrion, including New World vultures, raptors, foxes, and corvids.By the early 20th century, commercial exploitation and unregulated

Intro A wild mustang’s responses to abiotic and biotic factors can either be forced or an inclination. Their natural instinctive responses come out with mating, climate, competition, defense, food availability, and communication, while they are forced to respond to climate, and pollution. Wild mustang’s behaviors towards biotic factors have only somewhat changed over the years, as some biotic factors have not changed, while some have.
The bald eagle is the national symbol of the United States and was on the endangered list due to eggshell thinning which was caused by DDT. “DDE and its parent pesticide DDT were used to control mosquitoes and other insects. The chemical was linked to egg shell thinning in bald eagles. It was banned in 1972” (Murray). In 1995 the bald eagle was moved to the threatened species list and was removed from the list in 2007.
Bald eagles are known as the symbol of America, but they are also a symbol of adventure. In Yellowstone there are currently eighteen active nest. Female bald eagles are larger than their male counterparts, and they both have dark feathers and white heads. Juvenile bald eagles often have lighter colored feathers. Bald eagles nest is tall trees located near a water source, and during the spring and summer months they hunt waterfowl and fish. The winter months test the eagles’ survival. Bald eagles feed on animal carcasses during the harsh winters of Yellowstone. Bald eagles form life long bonds and lay two to three eggs a year that hatch in the spring. Yellowstone’s bald eagles stay in the park year round (Nat'l Park Service U.S Dept. of the
The gray wolf 's expressive behavior is more complex than that of the coyote and golden jackal, as necessitated by its group living and hunting habits. While less gregarious canids generally possess simple repertoires of visual signals, wolves have more varied signals which subtly inter grade in intensity. When neutral, the legs are not stiffened, the tail hangs down loosely, the face is smooth, the lips untensed, and the ears point in no particular direction. Postural communication in wolves consists of a variety of facial expressions, tail positions and piloerection. Aggressive, or self-assertive wolves are characterized by their slow and deliberate movements, high body posture and raised hackles, while submissive ones carry their bodies low, sleeken their fur and lower their ears and tail. When a breeding male encounters a subordinate family member, it may stare at it, standing erect and still with the tails horizontal to its spine. Two forms of submissive behavior are recognized: passive and active. Passive submission usually occurs as a reaction to the approach of a dominant animal, and consists of the submissive wolf lying partly on its back and allowing the dominant wolf to sniff its anogenital area. Active submission occurs often as a form of greeting, and involves the submissive wolf approaching another in a low posture, and licking the other wolf 's face. When wolves are together, they commonly indulge in behaviors such as nose pushing, jaw wrestling, cheek rubbing and facial
National Wildlife Federation is a wildlife organization founded by Ding Darling. The Wildlife Federation works to protect the ecosystem that is crucial to the native wildlife. The National Wildlife Federation took part in the passing of clean water act, clean air act, and endangered species act. In 2007 the water resources development act was successfully passed thanks to the help of the Wildlife Federation.
The United States of America abounds with beautiful scenery, amazing natural resources, and fascinating animals. Each state can boast of its unique natural resources. The state of Alaska provides an abundant habitat for numerous species of mammals, fish, and birds.
Desert bighorn sheep are the parks largest and most magnificent animals. They are always on the move, and very mobile (so they can go form water source to water source.) This is surprising as they have to carry up to 30 pounds of curling horns. Their agility is a critical factor for surviving in death valley. Along with the fact that they have a high ability to travel to water and high mountain slopes.
