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
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]
