Which Bird Can Not Fly
Many domesticated birds, such as the domestic chicken and domestic duck have lost the ability to fly for extended periods, few particularly bred birds, such as the Broad Breasted White Turkey, have become totally flightless as a result of selective breeding. The birds were bred to grow massive breast meat that weighs too much for the bird's wings to support in flight.
List of bird that can not fly
Penguin
Penguins are classified as birds (Aves) in zoological terms. They are black and white flightless seabirds of the family Spheniscidae which are found in the southern hemisphere, chiefly in the Antarctic (although several species live in more temperate regions).
Ostrich
Common Ostrich or simply Ostrich is a species of large flightless bird native to certain large areas of Africa. It is one of two extant species of ostriches, the only living members of the genus Struthio in the ratite order of birds. It is also known as the largest, (both heaviest and tallest) flightless bird which is also the largest living bird, it's a speed 70 km/h (Maximum, Adult, Running), height Male: 2.1 – 2.8 m (Adult), Female: 1.7 – 2 m (Adult) and weight is Male: 120 kg (East African race), Female: 100 kg (East African race).
Rhea
Rhea either of two species of large, flightless birds in the family Rheidae, order Rheiformes. Both species are considerably smaller than the ostrich; the common rhea stands about 120 cm (4 feet) tall and weighs about 20 kg (50 pounds). The common rhea has brown or gray, upperparts and whitish underparts while Darwin’s rhea is somewhat smaller in size, and its brownish plumage is tipped with white.
