The variation in dimensions and weights across birds is one of the fundamental sources of diversity among birds, and even Within species, dimensions may vary across populations within species , between the sexes and depending on age and ...

Ape index, ape factor, [1] or gorilla index is slang or jargon used to describe a measure of the ratio of an individual's arm span relative to their
The next largest living species is the king penguin, which grows to a maximum of 1 m (3.3 ft) in height and 18 kg (40 lb) in weight. [139] Now extinct, Anthropornis nordenskjoeldi, is believed to have reached a height of 1.8 m (5.9 ft) and a weight of up to 108 kg (238 lb). [140] The Eurasian eagle-owl is one of the biggest owls.

The common ostrich is the largest and heaviest living bird. Males stand 2.1 to 2.75 m (6 ft 11 in to 9 ft 0 in) tall and weigh 100 to 130 kg (220 to 290 lb), whereas females are about 1.75 to 1.9 m (5 ft 9 in to 6 ft 3 in) tall and weigh 90 to 120 kg (200 to 260 lb). [20]
A bird strike was recorded at this height in 1973. Common crane: Grus grus: Gruidae: 10,000 metres (33,000 feet) This height was recorded above the Himalayas. [2] This great height allows them to avoid eagles in mountain passes. [2] Bar-headed goose: Anser indicus: Anatidae: 8,800 metres (29,000 feet) [2] [4] [5]
The emu is the second tallest bird in the world, only being exceeded in height by the ostrich; [32] the largest individuals can reach up to 150 to 190 cm (59 to 75 in) in height. Measured from the bill to the tail, emus range in length from 139 to 164 cm (55 to 65 in), with males averaging 148.5 cm (58.5 in) and females averaging 156.8 cm (61.7 ...
They ranged in height from 1 to 3 m (3 to 10 ft). One of the largest specimens from the Early Pleistocene of Uruguay, possibly belonging to Devincenzia, would have weighed up to 350 kilograms (770 lb). [5] [6] Their closest modern-day relatives are believed to be the 80-centimetre-tall (31 in) seriemas.
