Which bird is the biggest
The answer to the question of which bird is the largest,not so unambiguous. The thing is that the largest bird that ever existed extincted several million years ago, and from living now - does not know how to fly at all.
The largest bird ever to exist on Earth
Historically, the largest bird everinhabited on the planet Earth - argentavis majestic. These huge flying creatures belonged to a group of Falconfishes and inhabited the planet about five to eight million years ago. They lived in the territory of modern Argentina. The wingspan of adults reached eight meters. The weight of these birds was not less than 70 kilograms, and the height was 1.5-1.8 meters. Despite the fact that the birds belonged to the order of the Falcon, their physique was more like the ancient storks. These ancient creatures were not scavengers and fed on rodents, absorbing them entirely, like modern owls. 
The biggest bird in the world
The largest of the living birds isAfrican ostrich. These creatures do not even know how to fly and can not boast of a giant wingspan. They have a muscular physique, a flattened head and an elongated neck. Their beak is wide and straight. These unusual birds belong to their own family and order - ostriches and ostriches. In height, they reach 2.7 meters and weigh up to 180 kilograms. Since these creatures do not fly, their chest and wings are not developed. However, these birds are real champions in the race - they can develop speeds of up to 70 kilometers per hour. This is due to well-developed legs, which have horns at the ends - they are supported by ostriches during movement. 
The habitat of African ostriches is the dry, impersonal savannas of Africa and the Middle East, mainly to the south or north of the African equatorial forests.
