Eagles
Introduction

Their fierce portraits stare out from cave paintings crafted by long-forgotten Stone Age masters. Their hooked beaks and deadly claws have adorned flags that led armies from Rome to Germany into battle. The spot on which one landed dictated to the ancient Aztecs the place where they were to build a city.

    

Humans have long revered eagles.

Eagles. For centuries, these seemingly larger-than-life birds have fascinated and inspired us.

We venerate them as living symbols of power, freedom, and transcendence. In some religions, high-soaring eagles are believed to touch the face of God. Legend holds that Mexico’s Aztecs so revered the birds that they built Tenochtitlan, their capital, at the spot where an eagle perched on a cactus.

Behind this extraordinary reverence, however, is the even more remarkable story of how Earth’s 59 species of eagles live their high-flying lives. That story is told in the NATURE program Eagles, which gives a rare bird’s-eye-view of these masters of the sky. Eagles documents the stunning acrobatics and the ferocious hunting skills that have made these birds the nobility of feathered society, from the plains of Africa and the rivers of Alaska to the forests of the Philippines and the seas off Japan.

When eagles come to mind, people commonly imagine some enormous hunter soaring above wide-open spaces on outsized wings. Indeed, eagles are among the world’s largest birds of prey. The largest, including the Harpy Eagle and the Philippine Eagle, can weigh more than 20 pounds and have wings that spread eight feet across. Using their massive, sharp talons, these giants can kill and carry off prey as large as deer and monkeys.

But not all eagles fit this stereotype: some are just small balls of feathers content to flap short distances, dining on insects or even fruit. The Crested Serpent Eagle, for instance, is no bigger than a pigeon and spends its days walking and climbing through its African forest home in search of snakes. And the African Vulturine Fish-Eagle is primarily a vegetarian, eschewing meat in favor of rich oil palm fruits.

Overall, scientists recognize four groups of eagles: The world’s 12 species of “serpent eagles” (also called “snake-eagles”) typically perch on trees and feed on snakes, frogs, and lizards. The six buzzard-like eagles are forest-dwelling giants, such as the Harpy and Philippine eagles, and prey on large mammals like deer.

    

Eagles glide for hours at a time.

The thirty “booted” eagles, so-called because feathers grow down the legs and cover the toes, include the widest-ranging eagle of them all: the Golden Eagle, which is found around the world and has learned to feast on an assortment of prey. In Greece, Golden Eagles even eat turtles, dropping them from great heights onto rocks to break open their armored shells. The eleven sea eagles, which include America’s beloved Bald Eagle, tend to specialize in eating fish and water birds — some even hunt flamingoes and poisonous sea snakes.

Biologists also recognize another significant difference among eagles: some are built to hunt in the tight confines of a forest, while others are designed to soar high above open plains and water with nary a wing flap.

The forest eagles, such as the Crested Serpent Eagle, have short wings and long tails that enable them to twist and turn easily — an advantage when chasing prey at high speed through tree trunks and branches. In contrast, soaring eagles, such as the Golden Eagle and Africa’s Bateleur Eagle, have short, wide tails and broad, long wings that enable them to glide effortlessly on rising air currents. There is a tradeoff, however: soaring eagles tend to be poor flyers, making every takeoff and landing an adventure! As a result, soaring eagles often hunt from high perches, where they can literally “fall” into the air and swoop down on unsuspecting fish and mammals. Still, soaring provides an efficient means of covering ground — a necessity for eagles living in areas where food may be scarce. Golden eagles nesting in Wyoming, for instance, often have foraging areas that cover 100 square miles.

To defend these territories and attract a mate, soaring eagles put on spectacular aerial displays. The airshows include death-defying swoops and seemingly suicidal dogfights — undertaken against both rivals and potential partners — that involve locking talons with the other bird and free-falling in a death spiral. The great American poet Walt Whitman, witnessing one of these breathtaking displays by Bald Eagles, described it as “a living, fierce, gyrating wheel,/ four beating wings, two beaks, a swirling mass tight grappling,/ in tumbling turning clustering loops, straight downward falling.” Sometimes, the dogfights end only when the great birds crash into a treetop or, in rare instances, one dies from hitting the ground.

    

Eagles are known for their sharp vision.

Usually, however, eagle eyes are too keen for the birds to fly blindly into danger. In fact, eagles’ vision is among the sharpest of any animal. Wedge-tailed Eagles, for instance, can see twice as far as people. Studies suggest that some eagles can spot an animal the size of a rabbit up to two miles away.

In part, eagles have excellent vision because their eyes, which are very large in proportion to their heads, are densely packed with sensory cells. While humans typically have 200,000 light-sensitive cells per square millimeter of retina, eagles may have 1 million — five times more. Similarly, while humans have only one fovea, a funnel-shaped part of the retina where vision is sharpest, eagles have two. Finally, where people see just three basic colors, eagles see five, enabling them to pick out even well-camouflaged prey.

Unfortunately, even such remarkable traits have not protected eagles from harm. Around the world, many eagle populations are dwindling as a result of habitat destruction, hunting, and pollution. But conservation efforts are helping some species. In the U.S., for instance, the Bald Eagle has made a dramatic comeback over the last few decades. And on the island of Madagascar, the dramatic 1993 rediscovery of the Madagascar Serpent Eagle has raised hopes that its population also can be protected and restored.

    Philippine eagles are known to carry off heavier prey than Harpy eagles and more ferocious like large snakes, monitor lizards and macaques large male monkeys can weigh as much as 20 lb. It was even documented to take a small deer to its nest about 14 kg and also documented to attack a large python.

    The eagle truly is a great bird. Just as God is a great God. We as God’s mouth piece must learn to ride out the storm. We must learn to soar above the trials that we face daily and realize that God is still on the throne, and still answering prayers. If my people who are called by my name would humble themselves pray and seek my face then will I hear from heaven and heal the land. The land needs healing and protection just as the eagles needs protection.

    great to have found this website while I was searching for some information on eagles lifespans. I received an e mail that had information that I wanted to check on. Do eagles go through a plucking and shedding process in old age that helps them to live longer? Being a conservationist, it sounds a bit unusual to me, but stranger things do happen. Can anyone shed some light on this?

  • Glenda

    I am also curious to know if it is true that eagles pluck their feathers, pull out their talons and shatter their beaks, at apparently age 30 or 40 years. Then a new beak, new talons and new feathers grow (approx 150 day peroid).This process allows them to live for another 30 odd years!?! Any comments?

    Regal Eagles are majestic and stoic creatures. They should not be caged, but should be allowed to fly free. Fly on eagles, fly on.

  • Derek Bibber

    I have been fortunate to live in Italy (serving in the US Air Force). My wife and I are raptor photographers on the side, and we’ve been blessed with seeing MANY different eagles… Short-toed Snake Eagles, Greater Spotted Eagles, Golden Eagles, Booted Eagles, Tawny Eagles, Stellar Sea Eagles, American Bald Eagles,Spanish Imperial/Eastern Imperial Eagles, Bataleur Eagles, African Fish Eagles and Steppe/Lesser Spotted Eagles. With exception to Golden, Short-toed Snakes and Greater Spotted Eagles, the above were seen at aviary centers (namely Burg Landskrom, and Burg Guttenberg in Austria and Germany, respectively.) It’s a blessing to see these creatures in real life and then captured on a show like this. Thank you so much PBS for educating all of us on these magnificant creatures!

  • joshua arogunyo

    i really want to know more about the eagle. i have seen an eagle just once in nigeria. i hope to still study more. thanks.

  • lobohawk

    Would you pull out your finger/toenails to have new ones grow in? Think about it – what garbage would anyone want to spread? Raptors moult (shed) feathers once a year for new ones to grow in – they do not pluck them. The beak and talons are constantly growing. Shattering their own beaks would do nothing for them except help them to starve to death. Large raptors such as eagles already have lifespans to 50+ years, longer in captivity (away from predators or natural dangers). Hope this helps.

  • Matonsky

    The eagles are symbolically recognized. They are well talked about in the bible too, of how great and mighty this animals are. They are not just any regular bird, like a goose, and ostrich, chicken and so on. It has a life span of 50 years, and more.

  • rudo

    i think you should post more information about eagles on my email. these animals are so wonderful. ask yourself this question why does God liken us to eagles in the bible. it’s because all the facts that you have read. have a vision of an eagle, soar like an eagle i think its amazing staff for those who do not believe it it’s your own loss

    It is pure internet-myth that Eagles shatter their beaks or pull out their talons.
    It’s a fabrication with the original intent of encouraging and strengthening people. Good intentions, for certain. But it has a totally opposite boomerang-effect once the truth is known.

    Especially if one has already incorporated the lie into their beliefs.

  • d2ba98

    excuse me uhhmm to lobohawk, I think eagles shatter their own beaks for survival and pluck their feathers because the feathers of the eagles at maybe 30-40 years it will be much heavier and it will be very hard and difficult for them to fly and they shatter their beaks because their beaks don’t grow straight, it grows pointing the heart of the eagle so if the eagles turn 50 years old, they can die because their beaks are sharp and it points their heart.. And also, the one you just said earlier, uhhhhmmmmmm, we cut our fingernails for new ones to grow isn’t that right? But for the point of view of the eagles, they can’t just shatter their beaks after a month or two just like our fingernails so they do it when it’s really abundant (at the age of 30-40). lobohawk, try not cutting your fingersnails for 30 years and we’ll see what happens… I’m sorry. I just want to correct what is wrong…=)

    I am aware of Eagle Hunters in Kazakhistan and seen videos how they hunt foxes and wolves. I am on the verge of abandoning my small orchard / farm operations in the Himalayan foothills because monkeys have become a big menace and do not allow any fruits or vegetables crops to grow. Dogs are not effective and electric fencing besides being non viable in my particular location, is too expensive. Can anyone suggest if a trained eagle could be a solution and how it can can be procured / purchased in India to scare / drive away the monkeys?

    Thanks for your article. My partner and i have usually observed that a lot of people are eager to lose weight because they wish to appear slim as well as attractive. Having said that, they do not always realize that there are many benefits to losing weight as well. Doctors claim that overweight people suffer from a variety of illnesses that can be perfectely attributed to their own excess weight. Fortunately that people who definitely are overweight along with suffering from several diseases are able to reduce the severity of their illnesses by losing weight. It is easy to see a progressive but identifiable improvement with health while even a negligible amount of weight-loss is realized.

  • Resilient Heart

    I have a facination for eagles…the most amazing bird of prey…It is full of strength..and independance…beautiful and amazing. I reside in Pakistan and where I live I see eagles almost everywhere..you lift your eyes upwards and see them soaring away..interestingly enough I happen to have build an affiliation with 2 eagles who spend their entire time either perched on high where they can watch me going about my chores..waiting impatiently for their food of the day….I have penned down a poem on them which I would like to share with you all cos this is just the right platform that I luckily happen to bump in today while I was searching for something on eagles.

    ~I hear him ..the whistling sound
    I know..I can tell..when he’s around..
    perched up high..pruning feathers
    as strong as steel,,
    waiting anxiously for his morning meal..
    I pack his favourite bite in a plastic wrap
    fling it accross..high up in the air ..
    in seconds he takes his regal flair..
    zooming down gracefully he clutches his scrap
    heads toward his usual kingly abode
    starts nipping ..devouring the long awaited food..
    And as I watch him soar above high
    looking above at the sky
    marvelling at the lightening speed of his pace
    my magnificient eagle and his flight of grace.
