Top 10 largest flying birds from around the world

10 – Kiwi – Average Weight: 3.5 kg (7 lb, 12 oz – Average Height: 55.9 cm (22 inches)

DNA sequence comparisons yielded the surprising conclusion that the kiwi bird is more closely related to the extinct Malagasy elephant bird than to the shared New Zealand moa.

There are five recognized species, two of which are currently endangered, another two of which are vulnerable, and one of which is near threatened.

9 – Kagu – Average Weight: 5.1 kg (11 lb, 0 oz – Average Height: 59.9 cm (23 inches)

It has long been one of the most enigmatic birds and in more recent times usually affiliated with the Gruiformes.

8 – Kakapo – Average Weight: 2.5 kg (5 lb, 8 oz) – Average Height: 66.0 cm (26 inches)

The kakapo is critically endangered; as of April 2018, the total known adult population was 149 living individuals, as reported by the Kakapo Recovery program, most of whom have not been named.

Due to Polynesian and European colonization and the introduction of predators such as cats, rats, ferrets, and stoats, the kakapo was almost wiped out.

7 – Fuegian Steamed Duck – Average Weight: 5.5 kg (12 lb, 2 oz – Average Height: 84.0 cm (33 inches)

The wingspan is 85-110 cm (33-43 in), the wings are too small to functionally allow the birds to fly.

Instead, the wings are used like paddles to help skim quickly across the surface of the water.

This species outnumbers any other wild species called “duck” and is about the same mass as the world’s largest wild goose, although this species is only distantly related to most true ducks.

Online game Cormorant that does not steal

6 – Stealth cormorant – Average weight: 4.5 kg (9 lb, 15 oz – Average height: 95.0 cm (37 in)

The cormorant that does not fly is also known as the Galapagos cormorant, is a native cormorant of the Galapagos Islands, and an example of the very unusual fauna.

It is unique in that it is the only cormorant that has lost the ability to fly.

It was once placed in its own genus, Nannopterum or Compsohalieus, although current taxonomy places it in the genus with most of the other cormorants, Phalacrocorax.

Emperor penguin

5 – Emperor Penguin – Average Weight: 29.4 kg (64 lb, 13 oz – Average Height: 114.0 cm (45 inches)

The emperor penguin is the tallest and heaviest of all living penguin species and is endemic to Antarctica.

Like all penguins, it does not fly, with a streamlined body, with stiff wings and flattened fins for a marine habitat.

4 – Rhea – Average Weight: 33.5 kg (55 lb, 2 oz) – Average Height: 137.1 cm (54 inches)

The genus name was given in 1752 by Paul Möhring and was adopted as the English common name.

3 – Cassowary – Average Weight: 33.5 kg (73 lb, 14 oz – Average Height: 152.4 cm (60 inches)

Cassowaries feed mainly on fruit, although all species are truly omnivorous and will take a range of other plant foods, including grass shoots and seeds, in addition to fungi, invertebrates, and small vertebrates.

Cassowaries are very shy, but when provoked they can inflict injuries, occasionally fatal, on dogs and humans.

2 – Emu – Average Weight: 40 kg (88 lb, 3 oz – Average Height: 152.4 cm (60 inches)

The emu range covers most of mainland Australia, but the Tasmanian emu and the King Island emu subspecies disappeared after the European settlement of Australia in 1788.

The bird is common enough to be considered the smallest species by the International Union for Conservation of Nature.

1 – Austria – Average Weight: 156.5 kg (345 lb, 0 oz – Average Height: 274.3 cm (108 in)

The diet of the common ostrich consists mainly of plant matter, although it also eats invertebrates.

It lives in nomadic groups of 5 to 50 birds.
