The bald eagle is the national bird as well as national animal of the United States of America. It's a uniquely North American eagle, ranging from northern Mexico through all of the contiguous United States, into Canada and Alaska. The only state the bird doesn't call home is Hawaii. The eagle lives near any open body of water, preferring a habitat with large trees in which it builds is nests. Bald eagles are not actually bald—by adulthood, they have white-feathered heads.
Mostly though, the fish eagles are Bald eagle sea are very near the surface of the water. Tree species reportedly is less important to the eagle pair than the tree's height, composition and location. Although we don't know precisely when the white-headed sea eagle our bald eagle evolved, there are numerous fossil remains, some from North Bald eagle sea as long as one million years ago. For example, eagles from South Carolina average 3. Now that we know how much What makes sexual atrraction themselves can weigh, we can use that to define how much they can lift. Wildlife Monogram.

Q: How much can a Bald Eagle lift? A: Bald eagles generally weigh between 4 - 6 kilograms, although some have been found both below and above this range, with some Alaskan eagles recorded with weights of well over 7 kg. Female eagles are the larger and heavier of the sexes. Now that we know how much eagles themselves can weigh, we can use that to define how much they can lift.
Of many prey items found in nests and weighed, a good general rule seems to be that eagles can carry up to half of their own weight. This obviously means female eagles are able to carry larger prey than the males. Sometimes, eagles have trouble judging the weight of prey. I've witnessed eagles in Alaska "lock on" to a large salmon, obviously heavier than could be carried away in flight, however the eagle is very capable of floating and "swimming" to shore with its prey, rather than give it up.
Then, dragged it up on shore, and the feasting began. Q: I have noticed in various books with photographs of Bald Eagles that their eye color can vary. I've seen blue, yellow, and brown. A: Generally, eagle eyes are pretty consistent in color.
Nestling eagles eyes are nearly black. Juvenile eagles first year birds just out of the nest , have brown eyes which can vary in how light or dark they are, but usually they are pretty dark. As they become immature eagles ages 2,3 , their eye lightens to a light brown.
As they get near sexual maturity age 4,5 , their eye turns yellow, and again can be in various shades of lighter to darker yellow, but usually quite light yellow. I believe that the darker eye color of juveniles and immatures may be a defensive mechanism, not seen as the threat yellow, adult eyes might be.
Similar coloration and gradual color shift to lighter and brighter are found in the bills of bald eagles as they age. I've never seen blue eyes in eagles though! Life Cycle. Q: In the wild, how long can Bald Eagles bear young? A: The life span of eagles in the wild is generally around 30 years. I can tell you that we captured one of our local breeders at her age 25 years, and she went on to breed and raise young successfully in her 26th year.
It is my opinion that eagles are probably productive until they die. It would be mal-adaptive for adult eagles to remain in the population as non-contributing members. Q: We know that dog life spans are 7 years to 1 human life span, so what is the eagle's life span to a human span? A: To answer that we have to explain how long eagles can live. In captivity a more coddled life But in the wild, their life is undoubtedly much shorter, either cut short by human beings, by other eagles, or by the rigors of their life.
In the wild, we believe eagles live around 30 years. Therefore, I guess you'd say an eagles life is about 2. Q: Do they reach a point like humans where they cannot bear young? For 3 years I have observed a nesting pair of Bald Eagles near my home. The pair has been nesting for 15 years in the same location. Last year the male crushed one egg in mid air.
The other made it to a first flight only, never to be seen after a few days. It stayed in a tree near the nest, but then died. The pair is currently nesting. A: I'm curious to know where you live! The mid-air egg-crushing you mention is quite strange and begs another question. I think, you are saying one young was fledged. Often, one of the adults will remove egg-shells from the nest after hatching; could you simply have seen egg-shells being "cleaned" out of the nest and dropped?
Adults will also sometimes remove whole eggs that don't hatch, fly from the nest with them and drop them they will also simply eat them in the nest. I have never heard of anyone witnessing "crushing" of an egg in mid-air. Perhaps it was one of these normal behaviors you witnessed. I have no idea what could have happened to the fledgling.
Again, after fledging, juveniles will often perch along the shore away from the nest for a long time, in hard to observe places. Were both adults present at the nest the whole season? Q: We live in Colorado and would like information on the migration path the eagles take in the mountain states and west coast. A: Colorado hosts a "winter" eagle population much larger than its summer breeding population, and most of these birds hail from Canada. Back in the 's and '80's an eagle researcher named Al Harmata captured wintering eagles in CO and studied their migration.
You might want to look up his work Ph. I believe some of his birds were tracked back to summering grounds in the Northwest Territories of extreme northwestern Canada and Saskatchewan. I would guess based on other studies and banding records that other CO wintering eagles come from British Columbia, Alberta, and perhaps Manitoba.
Also, a considerable amount of work on bald eagle migration in the western United States, particularly in Washington State, has been conducted by Jim Watson of the Washington State Department of Fish and Wildlife. Q: Who are their evolutionary ancestors? A: You mean besides reptiles? Only half-kidding. According to Mark Stahlmaster's wonderful book on bald eagles, the "sea eagles" of which the bald eagle is one of eight, began evolving tens of millions of years ago from a group of birds known as kites, which share many of the same characteristics of the sea eagles fishing, scavenging, breeding.
He states these ancient kites provided the genetic framework for an ancient sea eagle, which eventually evolved into eight separate sea eagle species. According to Mark, there are fossil remains of this ancient sea eagle at least 25 million years old. Although we don't know precisely when the white-headed sea eagle our bald eagle evolved, there are numerous fossil remains, some from North America as long as one million years ago.
Bald eagles are in the order " Falconiformes " including most raptors except owls , and the family " Accipitridae ", which includes species of eagles, hawks, kites, old world vultures and harriers. Our golden eagles are members of the "booted" eagles. Q: Where were the first sightings of the Bald eagle?
A: As mentioned above, bald eagles have been found in fossil remains in North America more than one million years old, including in tar pits in California and frequently in Indian middens throughout the continent.
The bald eagle is exclusively a bird of North America. I'm not sure what you mean exactly by "where were the first sightings", but I would bet that as early man crossed the land bridge from Asia through Alaska and migrated south, that they encountered eagles along the coastal areas not covered in ice. I'm sure native Americans living in New York and the east frequently encountered bald eagles, and surely captured and killed many for food and spiritual purposes. Later than that, on his journey up the Hudson River in , I'm sure Henry Hudson was privileged to observe bald eagles along the pristine shores of our Hudson River.
A: Golden eagle A20 was about 2 years old when he was captured, and is now 5 years old. Bald eagle V98 was a full adult when we captured it last March, so it was at least 5 years old.
We cannot say how old an adult is once it obtains its white head and tail adult plumage , unless it was previously banded. We recently trapped an eagle we had banded in , at 25 years of age.
Q: How many Bald Eagle eggs were laid in ? How many survived? A: In New York State, in , we confirmed 84 breeding pairs of bald eagles; 79 of these pairs laid eggs exact number unknown , and only 66 of these pairs were successful fledged young. A total of young were fledged, meaning that, on average, each of the 66 pairs fledged 1. Biologists believe that mostly, bald eagles lay two eggs, even if only one eaglet is hatched and fledged.
Of course, without numerous intrusions into the nests, we can't know exactly how many eggs are laid by every pair. Of the 13 of our pairs that failed, they laid at least 13 eggs, and possibly as many as About 5 percent of the time, eagle pairs will lay 3 eggs.
In addition, we recovered 10 unhatched eggs from 8 of the 66 successful nests. Every time I visit a nest to band young, I dig around the nest cup in search of buried, unhatched eggs.
These are valuable for contaminant and shell-thickness analysis. So, at least 23 more eggs were laid, and probably more, than the young we had this past year. Biologists believe that if eagles produce at least 1 young per breeding attempt, that the population will do fine and not decrease. Peter E. Nye New York State Dept. Bald Eagle.

Other Q: Who are their evolutionary ancestors?
The bald eagle, with its snowy-feathered not bald head and white tail, is the proud national bird symbol of the United States—yet the bird was nearly wiped out there. There are three additional bedrooms on this level. However, one nest in the Midwest was occupied continuously for at least 34 years. The Birds of North America Online.

DDT itself was not lethal to the adult bird, but it interfered with the bird's calcium metabolism, making the bird either sterile or unable to lay healthy eggs. Female eagles laid eggs that were too brittle to withstand the weight of a brooding adult, making it nearly impossible for the eggs to hatch.
In a New York City ornithologist wrote that in the state of Alaska in the previous 12 years approximately 70, bald eagles had been shot. Many of the hunters killed the bald eagles under the long-held beliefs that bald eagles grabbed young lambs and even children with their talons, yet the birds were innocent of most of these alleged acts of predation lamb predation is rare, human predation is thought to be non-existent.
In , the National Wildlife Federation listed hunting, power-line electrocution, and collisions in flight as the leading causes of eagle deaths. Bald eagles have also been killed by oil, lead, and mercury pollution, and by human and predator intrusion at nests.
The species was first protected in the U. Congress in , protected the bald eagle and the golden eagle , prohibiting commercial trapping and killing of the birds. The bald eagle was declared an endangered species in the U. Perhaps most significant in the species' recovery, in , DDT was banned from usage in the United States due to the fact that it inhibited the reproduction of many birds.
With regulations in place and DDT banned, the eagle population rebounded. The bald eagle can be found in growing concentrations throughout the United States and Canada, particularly near large bodies of water. In the early s, the estimated total population was , individuals, with ,—, by ;  the U. The most recent data submitted by individual states was in , when breeding pairs were reported. Today, the contiguous state with the largest number of breeding pairs of eagles is Minnesota with an estimated 1, pairs, surpassing Florida's most recent count of 1, pairs.
That number increased by about 30 per year, so that by there were occupied nests. Further population increases in Washington may be limited by the availability of late winter food, particularly salmon. The bald eagle was officially removed from the U.
In December , the U. Fish and Wildlife Service proposed quadrupling to 4, per year the amount of bald eagles that can be killed by the wind electric generation industry without paying a penalty.
If issued, the permits would last 30 years, six times the current 5-year permits. Permits are required to keep bald eagles in captivity in the United States.
Permits are primarily issued to public educational institutions, and the eagles which they show are permanently injured individuals which cannot be released to the wild. The facilities where eagles are kept must be equipped with adequate caging and facilities, as well as workers experienced in the handling and care of eagles. In Canada  and in England  a license is required to keep bald eagles for falconry. As a rule, the bald eagle is not the ideal choice for public shows, being timid, prone to becoming highly stressed, and unpredictable in nature.
Native American tribes can obtain a "Native American Religious Use" permit to keep non-releasable eagles as well. They use their naturally molted feathers for religious and cultural ceremonies. The bald eagle can be long-lived in captivity if well cared for, but does not breed well even under the best conditions. The bald eagle is important in various Native American cultures and, as the national bird of the United States , is prominent in seals and logos, coinage, postage stamps, and other items relating to the U.
The bald eagle is a sacred bird in some North American cultures, and its feathers, like those of the golden eagle , are central to many religious and spiritual customs among Native Americans. Eagles are considered spiritual messengers between gods and humans by some cultures.
Eagle feathers are often used in traditional ceremonies, particularly in the construction of regalia worn and as a part of fans, bustles and head dresses. In the Navajo Tradition an Eagle feather is represented to be a Protector, along with the Feather Navajo Medicine Man use the leg and wing bones for ceremonial whistles. In modern times, it may be given on an event such as a graduation from college.
During the Sun Dance , which is practiced by many Plains Indian tribes, the eagle is represented in several ways. The eagle nest is represented by the fork of the lodge where the dance is held.
A whistle made from the wing bone of an eagle is used during the course of the dance. Also during the dance, a medicine man may direct his fan, which is made of eagle feathers, to people who seek to be healed. The medicine man touches the fan to the center pole and then to the patient, in order to transmit power from the pole to the patient. The fan is then held up toward the sky, so that the eagle may carry the prayers for the sick to the Creator.
Current eagle feather law stipulates that only individuals of certifiable Native American ancestry enrolled in a federally recognized tribe are legally authorized to obtain or possess bald or golden eagle feathers for religious or spiritual use. The constitutionality of these laws has been questioned by Native American groups on the basis that it violates the First Amendment by affecting ability to practice their religion freely.
The National Eagle Repository , a division of the FWS , exists as a means to receive, process, and store bald and golden eagles which are found dead, and to distribute the eagles, their parts and feathers, to federally recognized Native American tribes for use in religious ceremonies.
On June 20, , the Continental Congress adopted the design for the Great Seal of the United States depicting a bald eagle grasping 13 arrows and an olive branch with thirteen leaves, with its talons. The bald eagle appears on most official seals of the U. Between and , the presidential flag but not the seal showed an eagle facing to its left the viewer's right , which gave rise to the urban legend that the flag is changed to have the eagle face towards the olive branch in peace, and towards the arrows in wartime.
Contrary to popular legend, there is no evidence that Benjamin Franklin ever publicly supported the wild turkey Meleagris gallopavo , rather than the bald eagle, as a symbol of the United States. However, in a letter written to his daughter in from Paris, criticizing the Society of the Cincinnati , he stated his personal distaste for the bald eagle's behavior. In the letter Franklin states: . For my own part. I wish the bald eagle had not been chosen the representative of our country.
He is a bird of bad moral character. He does not get his living honestly Franklin opposed the creation of the Society because he viewed it, with its hereditary membership, as a noble order unwelcome in the newly independent Republic , contrary to the ideals of Lucius Quinctius Cincinnatus , for whom the Society was named.
His reference to the two kinds of birds is interpreted as a satirical comparison between the Society of the Cincinnati and Cincinnatus. Largely because of its role as a symbol of the United States, but also because of its being a large predator, the bald eagle has many representations in popular culture.
Not all of these representations are accurate. In particular, the movie or television bald eagle typically has a bold, powerful cry. The actual eagle has a much softer, chirpy voice, not in keeping with its popular image; the call of the Red-tailed hawk is often substituted in movies and television.

Multiple birds of prey fall under the umbrella of "sea eagle", including African fish eagles, Steller's sea eagles, and bald eagles. Region: Arctic. Destinations: Greenland, North Norway.
Location : Close to rivers, lakes, and tidewaters worldwide except in South America. Conservation status : The eagles rank from Critically Endangered Madagascan fish eagle to Least Concern, depending on the species. Diet : Depending on location Fish, small mammals and birds, carrion, crabs, molluscs, sea snakes, crabs, tortoises.
Heads are either white or tan, depending on the species. All beaks feature a high arch. They will also steal food away from competitor birds like the osprey. If they catch a fish that is too heavy for them to fly away with they will swim all the way back to shore. It depends on the species, but for example the Bald Eagle travels at speeds between 30 to 50 km per hour, and can burst up to speeds of km per hour.
Like most bird species, Sea Eagles will mate for life, one of the pair only taking on a new mate if the other half of the pair dies. Nests are generally built in trees, the taller the better. If suitable trees are not available for example, for the Bald eagles found in Alaska the eagles may build their nests on a cliff.
Nests range in size from about 1. The nests are built so large because the hatchlings will grow to almost their full adult size before they leave. During this time they will start to practice their flight mechanics, which involves a lot of hopping up and down, so the nests have to be sturdy enough to take the repeated beatings. Females will lay from 1 to 3 eggs. The eggs are off-white and are about 7.
The parents will trade off incubating the eggs for a little over a month. Once hatched, the hatchlings generally have grey down feathers not flight feathers and weigh somewhere around 85 grams, depending on the species. The first egg that was laid is usually the first egg that hatches. The hatchlings known as eaglets will stay in the nest for about another 13 weeks.

Jump to navigation. Order Accipitriformes raptors and relatives , Family Accipitridae eagles, hawks, and relatives. The bald eagle is a large bird of prey that lives along the coastlines of freshwater and marine waterways throughout North America. It is an iconic symbol of the United States and is known for its dark brown or black body but solid white head.
Like the rest of the body, the head is covered with feathers. Bald eagles eat mostly fish, with a variety of coastal and freshwater species included in their diet. In other areas, the species takes advantage of the locally common fish species. They are also known to eat other birds, especially seabirds and waterfowl. Though bald eagles have a reputation for being impressive predators, they often scavenge dead animal matter or steal kill from other predators.
Like all water birds, bald eagles nest on land. They reproduce via internal fertilization and lay eggs in very large nests. In fact, their nests are the largest tree nests in the world. They use the same nest year after year, and over time, these nests end up being at least 13 feet 4 m deep and 8 feet 2.
Clutch size ranges from one to three, but two is the most common number of eggs that a pair of bald eagles cares for at a time. After hatching, juveniles receive some form of parental care for at least five months. Bald eagles cannot be legally hunted anywhere throughout their range, and populations are currently thought to be stable or even increasing. It is a species of least concern. This species has not always been in such good shape, though, and during the early to middle 20th century, bald eagle numbers plummeted, a result of intense directed hunting and significant accidental poisoning.
Poisoning by the common pesticide DDT was considered one of the primary reasons that numbers in the U. By the time the government of the U. Fortunately, conservation and management efforts have been successful, the species is expanding rapidly, in both numbers and geographic area, and it is no longer threatened by endangerment or extinction.
