The Dalmatian pelican Pelecanus crispus is native to Eurasia, usually found in rivers, lakes, and estuaries in southeastern Europe, Russia, India, and China. They are social birds, living and traveling mainly in flocks, and mating with one partner for life.
A smaller cousin of the southern cassowary, the northern cassowary Casuarius unappendiculatus is endemic to northern New Guinea. The females of the species are larger than the males, weighing up to 70 kilograms and standing 1. Despite their stocky build, the northern cassowary — also known as the single or one-wattled cassowary or gold-necked cassowary — can run in bursts at 50 kilometers an hour.
A mute swan — one of the heaviest flying birds. Both mute swans Cygnus olor and trumpeter swans Cygnus buccinator are similar build, height, and weight, and are two of the heaviest flying birds on Earth. These swans look graceful and elegant but have a dangerous side when defending their families or territories — standing up tall and hissing or assaulting intruders with their beaks and wings. Attacks on humans on water and land are relatively common. As with so many birds on this list, the greater rhea is flightless and fast, able to reach 35 kilometers per hour using their long, powerful legs.
Along with their high speeds, they protect themselves from predators by gathering in flocks of up to birds during the non-breeding season. Marabou storks Leptoptilos crumenifer are large wading birds found in Africa south of the Sahara — in both wet and arid habitats, often near human habitation, particularly landfill sites. Marabous are scavengers eating anything from termites, flamingos , and small birds and mammals to human refuse and dead elephants.
They also feed on carcasses with other scavengers such as vultures and hyenas. They have a wingspan of up to 3. Interesting maribou stork fact: they have hollow leg and feet bones, an adaptation to help them fly.
The solitary s hoebill stork Balaeniceps rex is a very large bird, growing up to 1. Males are usually taller than females and have much longer bills. All shoebills have a blue-gray, slaty plumage with black-tipped and green-tinted feathers. They are predominantly carnivorous birds, and their size — and enormous beak — allows them to hunt anything from water snakes to catfish, and even the occasional monitor lizard.
Wandering albatrosses feed by swooping down and skimming the surface of the water, which is the same place where they roost after the sun goes down. They eat a diet of fish and squid, and will sometimes follow fishing boats to eat discarded fish waste. For millions of years, the giant moa consisted of nine species of ostrichlike flightless birds native to New Zealand. While some species were about the size of a turkey, others stood as tall as 12 feet, Bird says, making it the tallest extinct bird.
Moas were mostly browsers and grazers, munching on seeds, fruits, leaves, and grasses. They were known to have swallowed four-inch stones to grind up their food, and females made one-egg nests in hollows in the ground. For millions of years, they marched through their habitat but suddenly went extinct about years ago. The largest falcon over most of North America, peregrine falcons are crow-sized raptors with long, pointed wings and a long tail. They are the fastest moving bird in the world, but not to be confused with the fastest flying bird, Bird says.
That title belongs to the red-breasted merganser. Adult peregrine falcons sport a coat of blue-gray feathers with barred white underparts. Medium-sized flyers, they can grow 14 to 19 inches long and weigh roughly three pounds. The falcons have yellow feet with hooked claws and sharp beaks, which they use to hunt pigeons, shorebirds, and ducks. They sit on high perches, waiting for the perfect moment to swoop down after prey. At one point, peregrine falcon populations were threatened because chemicals such as DDT were making their eggs so fragile that they would crack when the birds went to sit on them.
But today, with the passing of environmental regulations, peregrine falcon populations are thriving.
They can be commonly seen on skyscrapers, water towers, cliffs, and other tall structures. All rights reserved. Year of the Bird.

It breeds from southeastern Europe to India and China. Andean condor Vultur gryphus can reach a weight of 11 to 15 kg 24 to 33 lb for males and 8 to 11 kg 18 to 24 lb for females. Overall length can range from to cm 3 feet 3 inches to 4 feet 3 inches. It also has a very large wingspan, up to 3. Andean condor plays an important role in the folklore and mythology of the South American Andean regions. It is the national bird of Bolivia, Chile, Colombia, and Ecuador.
Trumpeter swan Cygnus buccinator is one of the heaviest flying bird species in the world. They are native to North America, and the heaviest birds living there. They also have a very large wingspan, which can exceed 3 meters 10 feet. The largest known male trumpeter attained a length of cm 6 ft 0 in , a wingspan of 3. At one point in history, the trumpeter swan was dragged to near extinction: in the 19th and early 20th centuries, they were hunted heavily. By , fewer than 70 wild trumpeters were known to exist in remote hot springs in or near Yellowstone National Park, and the extinction seemed inevitable.
This population provided critical genetic stock and with careful reintroductions by wildlife agencies, the Trumpeter Swan Society population gradually increased to over 46, birds by The Great bustard Otis tarda and Kori bustard are probably the heaviest living flying animal. A male Great bustard is typically 90— cm 2 ft 11 in-3 ft 5 in tall, with a length of around cm 3 ft 9 in , and has a 2. The male can range in weight from 5.
Females are much smaller, weighing from 3. The Kori bustard Ardeotis kori is native to Africa. The male kori bustard is to cm 3 ft 11 inches to 4 ft 11 inches , stands cm 2 ft 4 in-3 ft 11 in tall and may have a wingspan about to cm 7 feet 7 in ches to 9 feet 0 inches.
Male birds may typically weigh between 7 and 18 kg 15 and 40 lb. Females weigh an average of 4. The average weight of the King penguin Aptenodytes patagonicus is similar or just slightly higher than that of the largest living flying birds — the Great bustard and the Kori bustard.
They stand at 70 to cm 28 to 39 in tall and weighs from 9. Males are slightly larger than females. It is the second-largest species of penguin the largest is the Emperor penguin. The dwarf cassowary Casuarius bennetti is between 99 and cm 3. It is distributed throughout mountain forests of New Guinea, New Britain, and Yapen Island, at elevations up to 3, m 10, ft. Length is 92 to cm 36—39 in and weight is 15 to The domesticated turkey Meleagris gallopavo was probably domesticated in central Mesoamerica at least 2, years ago.
Weighing kilograms lb , the greater rhea Rhea americana is the largest bird on the American continent. The emperor penguin Aptenodytes forsteri is endemic to Antarctica. Reaching cm 51 in in height and weighing from 22 to 45 kg 49 to 99 lb , it is the tallest and heaviest of all living penguin species. The male and female emperor penguins are similar in plumage and size. Emus weigh between 18 and 60 kg 40 and lb. Today, they are considered Critically Endangered.
Harpy Eagle. Tipping the scales at 20 pounds — the approximate weight of two bowling balls — the Harpy Eagle is the largest hunting bird in the Americas. This apex predator, which is found in areas of extensive lowland forest in Central and South America, sports legs comparable in girth to a human arm and talons the size of Grizzly Bear claws. As if that wasn't enough, Harpy Eagles are equipped with owl-like facial disks that pick up even the faintest sounds, leading them to sloths, monkeys, and other prey.
These big hunters occupy vast hunting territories, sometimes exceeding 10, acres in size. But finding large, healthy forest tracts is becoming more difficult as tropical woodlands disappear — and the strain is showing as Harpy populations decline.
They are now considered Near Threatened. Luckily, they are not without defenders. Golden Eagle. With a wingspan topping seven feet, Golden Eagles are the largest hunting birds in North America. And they aren't just big birds — Golden Eagles are among the most formidable winged hunters in the world, capable of diving on prey at speeds approaching miles per hour.
While subsisting typically on rabbits, squirrels, and prairie dogs, Golden Eagles have been known to feed on much larger animals, including: seals, bighorn sheep, pronghorn, coyotes, and bobcats.
Their range, which wraps around much of the Northern Hemisphere, is the largest of any eagle. In North America, this includes everything from desert to arctic environments, although they are primarily found in the western United States.
Despite passage of protective legislation in the United States, these birds are not free of human threats. One of the biggest dangers comes from the ever-growing gauntlet of wind turbines built in critical habitat. The following year, ABC challenged the rule and scored a major victory for eagles when it was rescinded in Act by December 31! Donate Now.
