The common crane is a large, stately bird and a medium-sized crane. It is 100–130 cm (39–51 in) long with a 180–240 cm (71–94 in) wingspan. The body weight can range from 3 to 6.1 kg (6.6 to 13.4 lb), with the nominate subspecies averaging around 5.4 kg (12 lb) and the eastern subspecies (G. g. lilfordi) averaging 4.6 kg (10 lb).
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]

Bird measurement or bird biometrics are approaches to quantify the size of birds in scientific studies. 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 ...
Cranes are very large birds, often considered the world's tallest flying birds. They range in size from the demoiselle crane, which measures 90 cm (35 in) in length, to the sarus crane, which can be up to 176 cm (69 in), although the heaviest is the red-crowned crane, which can weigh 12 kg (26 lb) prior to migrating.
