3. Emu


Like a smaller, but shaggier ostrich, the Emu is a 5 to 6-foot bird known as one of the largest birds on the planet (as well as a goofy and impressive spokes bird for insurance).

When it’s the breeding season, the female emus will fight enthusiastically over the available unattached males.

6. Mute Swan

The mute swan is one of the largest and heaviest birds that fly in the skies. mute swans are so cute and look harmless as they glide over lakes, rivers, and ponds.

But don’t be fooled as mute swans are far from being silent birds when it comes to defending their territory and families. Male swans are known to warn interlopers when they’re getting too close with a loud hiss.

After the warning, they can then launch a straight-up assault, which will see them bashing the intruder with their large wings. They’ll even go as far as attacking canoeists, kayakers, and random people who are just minding their business.

7. Andean Condor

Andean Condor

This is a freakishly large vulture that isn’t satisfied with any random carrion —it prefers large carcasses like deer and cattle for dinner. Maintaining its average body weight of 25 pounds demands a lot of calories.

Its wingspan is slightly shorter than that of its northern cousin, known as the California condor. However, it still gets to a crazy wide 9 to 10 feet; and one of the biggest and largest birds in the world.

8. Cinereous Vulture

Cinereous Vulture

Another largest bird in the world that comes with a 10-foot wingspan is the Cinereous Vulture. This vulture from the old world comes with excellent vision to notice carrion while it flies high up, and a bald featherless head that fights against the accumulation of gore when it eats.

Though it is quite intimidating and ugly to look at, the cinereous vulture is known to play an essential role in its ecosystem as it cleans up roadkills and other lifeless animals.

9. Marabou Stork

As if the red-tinged wattle, dagger-esque bill, and black back weren’t alarming enough, the bold marabou stork is often known as the “undertaker bird” thanks to its Dracula-like look. It is also known to eat other birds.

So far, the largest verified wingspan on any marabou stork measured as massive 10.5 feet. However, some unverified reports claim a specimen with a vast 13.3-foot span.

10. Shoebill


Shoebill storks may be cute in cartoons and may also not be the world’s heaviest, tallest, or widest-winged birds, but they sure are one of the biggest and largest birds in the world with scary looks.

On top of having a wide and flat nutcracker for a face, the shoebill with its 5-foot-tall self leads a very fearsome lifestyle.

The shoebill stands absolutely still for many hours to hunt its prey. It watches for baby crocodiles or lungfish, then spreads its broad wings and collapses over the victim while trapping the target in its big flat bill.
