<\/p>\nBald eagles are powerful symbols of America\u2014but there\u2019s a whole lot more to these quirky\u00a0birds.<\/p>\n
So obviously adult bald eagles aren’t really bald, either\u2014their heads have bright white plumage that contrasts with their dark body feathers, giving them a “bald” look. But young bald eagles have mostly brown heads. In fact, for the first four or five years of their lives, they move through a complicated series of different\u00a0plumage patterns; in their second year, for instance, they have white bellies.<\/p>\n
<\/p>\n
It’s a scene you\u2019ve probably seen countless times in movies and on TV: An eagle flies overhead and emits a rough, piercing scream. It’s a classic symbol of wilderness and adventure. The only problem? Bald eagles don’t make that sound.<\/p>\n
Instead, they emit a sort of\u00a0high-pitched giggle or a weak scream. These noises are so unimpressive that Hollywood sound editors often\u00a0dub over\u00a0bald eagle calls with far more impressive sounds: the piercing, earthy screams of a smaller bird, the red-tailed hawk. If you were a fan of\u00a0The Colbert Report<\/em>, you might remember the show’s iconic\u00a0CGI eagle\u00a0from the opener\u2014it, too, is making that red-tailed hawk cry.\u00a0Listen\u00a0for yourself and decide who sounds more impressive.<\/p>\n Picture a majestic bald eagle swooping low over a lake and catching a fish in its powerful claws. Yes, bald eagles eat a lot of fish\u2014but they don’t always catch them themselves. They’ve perfected the art of stealing fish from other birds such as ospreys,\u00a0chasing them down\u00a0until they drop their prey.<\/p>\n Bald eagles will also snack on gulls, ducks, rabbits, crabs, amphibians, and more. They’ll scavenge in dumpsters, feed on waste from fish processing plants, and even gorge on carrion (dead, decaying animals).<\/p>\n Trash and carrion aside, they’re pretty romantic animals. Bald eagles tend to\u00a0pair up for life, and they share parenting duties: The male and the female take turns incubating the eggs, and they both feed their young.<\/p>\n Those romantic partnerships are even more impressive because bald eagles can survive for decades. In 2015, a wild eagle in Henrietta, New York, died at the\u00a0record age of 38. Considering that these birds pair up at 4 or 5 years of age, that’s a lot of Valentine’s Days.<\/p>\n Bald eagles build enormous nests high in the treetops. The male and female work on the nest together and this quality time helps them cement their lifelong bond. Their cozy nurseries consist of a framework of sticks lined with softer stuff such as grass and feathers. If the nest serves them well during the breeding season, they’ll keep using it year after year. And, like all homeowners, they can’t resist the thought of renovating and adding to their abode. Every year, they’ll spruce it up with a whopping foot or two of new material.<\/p>\n On average, bald eagle nests are\u00a02-4 feet deep and 4-5 feet wide. But one pair of eagles near St. Petersburg, Florida, earned the\u00a0Guinness World Record\u00a0for largest bird\u2019s nest: 20 feet deep and 9.5 feet wide. The nest weighed over two tons.<\/p>\n In many animal species, males are (on average) larger than females. Male gorillas, for example, dwarf their female counterparts. But for most birds of prey, it’s the opposite. Male bald eagles\u00a0weigh about 25 percent less\u00a0than females.<\/p>\n Scientists aren’t sure why there’s such a size difference. One reason might be the way they\u00a0divide up their nesting duties. Females take the lead in arranging the nesting material, so being bigger might help them take charge. Also, they spend longer incubating the eggs than males, so their size could intimidate would-be egg thieves.<\/p>\n If you’re trying to tell male and female eagles apart, this size difference may help you\u2014especially since both sexes have the same plumage patterns.<\/p>\n People often get excited about a big soaring bird and yell “It’s an eagle!\u201d just before it swoops closer and \u2026 oops, it’s a vulture. Here’s a handy identification tip. Bald eagles usually soar with their wings almost flat. On the other hand, the turkey vulture\u2014another dark, soaring bird\u2014holds its wings up in a shallow V shape called a\u00a0dihedral. A lot of large hawks also soar with slightly raised wings.<\/p>\n Before European settlers arrived, bald eagles were abundant across the U.S. But with settlement came habitat destruction, and the settlers viewed the eagles as competition for game and as a threat to livestock. So many eagles were killed that in 1940 Congress passed an act to protect the birds.<\/p>\n Unfortunately, another threat rose up at about that time. Starting after World War II, farmers and public health officials used an insecticide called DDT. The chemical worked well to eradicate mosquitos and agricultural pests\u2014but as it traveled up the food chain, it began to heavily affect birds of prey. DDT made eagle eggshells too thin and caused the eggs to break. A 1963 survey found\u00a0just 471 bald eagle pairs\u00a0in the lower 48 states.<\/p>\n DDT was banned in the early 1970s, and conservationists began to breed bald eagles in captivity and reintroduce them in places across America. Luckily, this species made a spectacular recovery. Now the lower 48 states boast\u00a0over 9700 nesting pairs.<\/p>\n You’ve probably heard of America’s other eagle: the golden eagle. This bird lives throughout much of the northern hemisphere. But the bald eagle\u00a0is only found in North America. It lives across much of Canada and the U.S., as well as northern parts of Mexico.<\/p>\n Though it may be North American, the bald eagle has seven close relatives that are found throughout the world. They all belong to the genus\u00a0Haliaeetus<\/em>, which comes\u2014pretty unimaginatively\u2014from the Latin words for “sea” and “eagle.” One relative, the African fish eagle, is a powerful symbol in its own right. It represents several countries; for example, it’s the national symbol of Zambia and graces the South Sudanese,\u00a0Malawian, and\u00a0Namibian\u00a0coats of arms.<\/p>\n It seems too weird to be true: While flying, bald eagles sometimes grab each other’s feet and\u00a0spin while plummeting\u00a0to the earth. Scientists aren’t sure why they do this\u2014perhaps it’s a courtship ritual or a territorial battle. Usually, the pair will separate before hitting the ground (as seen in this remarkable\u00a0set of photographs). But sometimes they hold tight and don’t let go. These two\u00a0male bald eagles\u00a0locked talons and hit the ground with their feet still connected. One subsequently escaped and the other was treated for talon wounds.<\/p>\n What if you could close your eyes and still see? Besides the usual pair of eyelids, bald eagles have a see-through eyelid called a\u00a0nictitating membrane. They can close this membrane to protect their eyes while their main eyelids remain open. The membrane also helps moisten and clean their eyes.<\/p>\n Eagles also have sharper vision than people, and their\u00a0field of vision\u00a0is wider. Plus, they can see ultraviolet light. Both of those things mean the expression “eagle eye” is spot-on.<\/p>\n If you’re a bald eagle that nests in northern Canada, you’ll probably head south for the winter to avoid the punishing cold. Many eagles fly south for the winter and return north for the summer\u2014as do plenty of other bird species (and retired Canadians). But not all bald eagles migrate. Some of them, including individuals in New England and Canada’s Maritime provinces,\u00a0stick around all year. Whether or not a bird migrates depends on how old it is and how much food is available.<\/p>\n There are several\u00a0videos online\u2014like the one above\u2014that shows a bald eagle swimming in the sea, rowing itself to shore with its huge wings. Eagles have hollow bones and fluffy down, so they can float pretty well. But why swim instead of soar? Sometimes, an eagle will swoop down and grab an especially weighty fish, then paddle it to shore to eat.<\/p>\n Note that the announcer in the video above says that the eagle’s talons are “locked” on a fish that’s too heavy to carry. In fact, those lockable talons are an\u00a0urban legend.<\/p>\n","protected":false},"excerpt":{"rendered":" Bald eagles are powerful symbols of America\u2014but there\u2019s a whole lot more to these quirky\u00a0birds. 1.
