Top 10 Largest Birds on Earth | Wingspans

What birds have the longest wingspans?


B
irds are some of the most well-known animals on earth -- mainly because they are everywhere! Filling up otherwise empty places with life, color, and song. Have you ever wondered what the largest birds on earth are? Well, this page seeks to answer that question! The following is a list of the top ten longest WINGSPANS of living species. Please note that this is not a list by bird mass or body size. Some of these wingspans will truly amaze you! I have also included some interesting bird facts and information as well --- and please don't forget to sign the guestbook before you leave.
There are about 10,000 different bird species on earth. Since the year 1500 over 190 bird species have become extinct -- and extinction is on the rise.

New bird species are still being discovered today in remote places around the world.

I've been fascinated by birds since I was a little girl -- the diversity in bird size and shape is amazing! I am so interested in birds that I am currently in grad school studying avian migration biology. Now...time to learn about what bird species have the longest wingspans in the world....

Largest Bird on Earth:

The largest living bird species on earth is the Ostrich (Struthio camelus). Ostriches cannot fly, but are excellent runners!
Meanwhile, the bee hummingbird (Mellisuga helenae) is the smallest bird species in the world.
A wingspan is simply the measurement of a bird's wings from one primary feather tip to the other. Similar to this airplane photo from Wiki Commons:

Top 10 bird species with the longest wingspans

10. Golden Eagle

Aquila chrysaetos

Wingspan: 8.2 feet

Golden eagles are majestic and powerful hunters of the Northern Hemisphere and are one of the largest eagles in the world. Although they are powerful enough to kill a large deer, they most often hunt small mammals such as rabbits, ground squirrels, and prairie dogs. Golden eagles are the National Emblem of Mexico. Have you ever seen one? I was thrilled to recently see a golden eagle for the first time!

9. Grey Crowned Crane

Balearica regulorum


Wingspan: 8.2 feet (2.5 meters)


The grey crane is an inhabitant of the dry savannas in Africa. They have an elaborate courtship display which involves dancing, bowing, and jumping. An elegant bird that is only found south of the Sahara desert. I'd love to take a trip to Africa someday and hope to see these elegant cranes!

8. California Condor - the largest flying bird in North America

Gymnogyps californianus

Wingspan: 9.1 feet (2.8 meters)

The California Condor is one of the rarest birds in the world. Pushed to the brink of extinction, they are now slowly and steadily increasing in numbers with the aid of some excellent captive breeding programs. They are the largest flying bird in North America and feed on carrion. The number of California Condors was reduced dramatically by poisoning, both intentionally by farmers and unintentionally by the use of lead shot to hunt animals. Lead poisoning as a result of scavenging rendered many of these birds infertile. This is a story with a happy ending though!

Have you ever seen one of these magnificent birds?

7. Griffon Vulture

Gyps fulvus

Wingspan: 9.2 feet (2.8 meters)

This is a massive vulture which measures over three feet from beak to tail. It hunts for carrion by soaring high in the sky, either singly or in large groups. These birds inhabit the mountainous parts of Southern Europe, North Africa, and Asia. It breeds on high cliff edges - this is not a bird that's scared of heights! Noted as being a highly social species, these birds often nest in colonies of more than 100 pairs, with some colonies estimated to contain up to 1,000 birds.

Some people think that vultures are creepy, but I think they're a cool group of birds.

6. Bearded Vulture

Gypaetus barbatus

Wingspan: 9.8 feet (2.99 meters)

The Latin binomial for this species literally means "bearded vulture-eagle" and it is aptly named. This is a massive and majestic species! Sometimes known as the Lammergeier vulture. Unlike most vultures, this species does not have the characteristic bald head. It inhabits the crags in the high mountains of Europe, India, Pakistan, Africa, and Tibet. Like most vultures, they eat mostly carrion which they locate by sight while soaring high in the air. Amazingly, a bearded vulture has been reported at an elevation of 24,000 feet!

5. Whooper Swan

Cygnus cygnus

Wingspan: 9.8 feet (3 meters).

Some of the heaviest flying birds are our swans -- in the US the heaviest flying bird is the Trumpeter Swan, but the Whooper Swan is an elegant bird that winters in northern Europe and eastern Asia. They may fly hundreds of miles to reach breeding grounds in subarctic Eurasia. These birds are powerful flyers, despite weighing 18-44 pounds (8-20 kilograms)! They have a very deep call and are truly a remarkable bird to witness in flight.

4. Andean Condor

Vultur gryphus

Wingspan: 11 feet (3.4 meters)

This is a magnificent and humungous bird! These massive vultures spend the days soaring on updrafts in the Andean Mountains of South America. Most of its diet consists of carrion, but unlike most vultures, these birds will kill small to medium sized mammals as well. They do not reach maturity until they are around eight years old and can live 50 to 60 years in the wild. Males are larger than females and can weigh over 30 pounds. A remarkable sight when soaring!

It is sometimes difficult to imagine just how large these bird wingspans can be by simply reading a number. Here is a scale with a roughly 6 foot tall human to help put things into perspective (wow):

3. Marabou Stork

Leptoptilos crumeniferus


Wingspan: at least 11 feet (3.4 meters)

These unusual scavengers are a frequent sight on the African plains feeding on carrion alongside vultures. These impressive birds inhabit both wet and arid habitats south of the Sahara. They are often called "undertaker birds" because of their habits. They are gregarious and colonial breeders. They can weigh up to 20 pounds and can reach a height of 60 inches. Although they usually eat carrion, they will also eat small mammals, birds, and nestlings.

2. Great White Pelican

Pelecanus onocrotalus

Wingspan: 11.8 feet (3.6 meters)

These are large and distinct birds that inhabit the eastern Mediterranean to Vietnam and South Africa. Like all pelicans, these birds are adapted to aquatic life. They have webbed feet and feed on many fish per day, but like most birds are opportunistic feeders. They are known for forming huge aggregations, including a colony of around 75,000 in Tanzania. Please note that this is not the American White Pelican, which inhabits the states.

1. Wandering Albatross

Diomedea exulans

Wingspan: 11.8 feet (3.6 meters)

These are amazing and majestic birds. They spend their entire lives at sea and only come ashore to reproduce every other year. The Wandering Albatross breeds on South Georgia Island, Crozet Islands, Kerguelen Islands, Prince Edward Islands, and Macquarie Island. Although the largest confirmed report was around 12 feet, there have been accounts of Wandering Albatross wingspans as large as 17 feet across. Such long wings enable these birds to glide effortlessly over the ocean for hours at a time without flapping its wings. Its body length can reach close to five feet in length. Unfortunately, these majestic birds have declined by more than 30% in 70 years with their biggest threat being long line fishing practices. However, pollution, especially from plastic is also taking its toll. Adults unknowingly feed their chicks bits of plastic they find floating in the ocean, causing a slow death for the unfortunate chick.
