Females are slightly larger than males. Today, the Emu is endemic to Australia. The Tasmanian emu and King Island emu subspecies became extinct after the European settlement of Australia in The Northern cassowary Casuarius unappendiculatus is a large, bulky bird native to northern New Guinea.
Females can weigh up to 70 kg lb , with an average weight of 58 kg lb. Males are smaller. Despite its stocky build, a Northern cassowary can sprint up to 50 kilometers per hour 31 miles per hour.
The southern cassowary Casuarius casuarius is distributed in tropical rainforests of Indonesia, New Guinea, and northeastern Australia, and it prefers elevations below 1, m 3, ft in Australia and m 1, ft in New Guinea.
In general, the bird ranges from to cm in and weighs around 36 to 50 kg males and 68 kg females. The maximum size recorded was cm 75 in tall and 83 kg lb weight. The southern cassowary is the largest extant Asian bird since the extinction of the Arabian ostrich, and previously the moa of New Zealand and the largest extant Australian bird though the emu may be slightly taller. The second-largest living bird on Earth, Somali ostrich Struthio molybdophanes is a large flightless bird native to the Horn of Africa, especially in north-eastern Ethiopia and across all of Somalia.
It was previously considered a subspecies of the common ostrich but was identified as a distinct species in The ostrich or common ostrich Struthio camelus is the largest living bird on Earth. It is native to Africa. They usually weigh from 63 to kilograms lb , or as much as two adult humans. Exceptional male ostriches can weigh up to Male ostriches can be from 2. Ostriches have large, powerful legs. Although its bulky body means that flying is out of the question, the ostrich has adapted to life on the ground with impressive agility.
This also makes the ostrich the fastest animal on two legs. Measuring from 2. Wandering albatross is also one of the most far-ranging birds. Some individual wandering albatrosses are known to circumnavigate the Southern Ocean three times covering more than , km or 75, miles in one year.
The Philippine eagle Pithecophaga jefferyi is considered the largest of the extant eagles in the world in terms of length and wing surface. It is typically reported as measuring cm 2 ft 10 in-3 ft 4 in in total length. It also has a wingspan of to cm 6 ft 0 in to 7 ft 3 in. Among condors, which are also considered birds of prey though they are primarily scavengers, the title goes to the Andean condor. Until recently, the Aepyornis maximus , a bird endemic to Madagascar until its extinction about A.
D was regarded as the largest bird of all time. However, in the largest aepyornithid specimens, weighing up to kilograms 1, lb , were moved to the related genus Vorombe.
Vorombe is one of three genera of elephant birds. But, in a study, James Hansford and Samuel Turvey, two researchers from the Zoological Society of London, found that it was sufficiently distinct from Aepyornis and allocated it in the new genus Vorombe. They also recognized Aepyornis ingens as a synonym of Vorombe titan. Vorombe titan weighed to kg mean: Though they live at opposite ends of the Americas, both are long-living animals that scavenge on dead mammals.
In terms of body length, the California condor is around 1. However, when it comes to weight 15 kilograms and wingspan 3. What do you think — did any of the giant birds on this list surprise you?

Domestic turkey — too fat to fly! With near constant wind in their environment, albatrosses are able to "lock their elbow joints and literally just fix their wings [in place] and just glide," Angel said.
The birds also use something called "dynamic soaring," which involves changing the angle of their wings relative to the wind, to maximize the lift generated — a similar technique could help unmanned research aircraft stay aloft for months, the Independent reported. Related: A hot blob in the Pacific Ocean caused 1 million seabirds to die. An albatross can go a year or more without setting foot on land, Angel said, although the birds do touch down in water in order to feed on the squid and fish that make up their diet.
In fact, it's the tiny alpine swift, not the albatross, that holds the record for non-stop distance flying, as reported in a study published in the journal Nature Communications. As for sleep, Angel said that it's very likely that albatrosses sleep on the wing. A study published in Nature Communications described how a distant cousin of the albatross, the frigatebird, has many, seconds-long periods of sleep while flying, suggesting that sleeping in the air is definitely possible for other long-distance traveling seabirds.
And, based on microchip-tracked movements of albatrosses, "they can [fly] for hours on end, and so it is theorized that they do sleep on the wing," Angel said.
All albatrosses are very long-lived. The oldest wild bird in the world is a Laysan albatross Phoebastria immutabilis named Wisdom, who was tagged in at the Laysan albatross colony at Midway Atoll in the North Pacific Ocean when she was already a mature adult. That makes her at least 66 years old, but she's likely older, and she's still going strong — as of she was still raising chicks, NPR reported.
According to Breck Tyler, a lecturer at the University of California, Santa Cruz and retired research scientist who studied the Laysan albatross colony on Midway Atoll for decades, there are other Laysan albatrosses just a few years younger than Wisdom, so "she's probably not an outlier.

The wandering albatross can only dive about 2 to 3 feet 0. Trumpeter swans weigh slightly less at A Polish mute swan cob Cygnus immutabilis , a morph of the mute swan, and a pure white version with pink legs instead of the usual black colour, has been verified as the largest bird to take flight weighing in at 23 kg.
Great bustards Otis tarda weigh on average Great bustards were driven to extinction in the UK by trophy hunters in the s but have recently been introduced and are breeding on Salisbury Plain.
The wandering albatross Diomedea exulans is also known as the snowy albatross, the white-winged albatross and the goonie. It weighs an average It has the longest wingspan of any living bird ranging from 2. Wandering albatrosses spend most of their life in flight and can remain in the air without flapping for several hours at a time. Albatrosses have some of the longest ranges of all birds and some individual wandering albatrosses have been known to circumnavigate the Southern Ocean three times in one year.
The Dalmatian pelican Pelecanus crispus is the largest member of the pelican family and perhaps the largest freshwater bird in the world rivalled in length and weight by swans. It has a wingspan similar in size to the great albatrosses and is one of only 4 species of birds having verified wingspans of over cm, the others being the wandering albatross, the southern royal albatross and the great white pelican. Dalmatian pelicans are found in lakes, rivers and estuaries in south east Europe, Russia, India and China.
During the 20th century the population underwent a drastic decline in numbers most likely due to habitat loss caused by the drainage of wetlands. Never realised penguins were so big. Thought they were small birds until I read this. Is it ok to share on my Facebook? Thanks in advance. Your email address will not be published.
