Beau Geste hypothesis
The Beau Geste hypothesis in animal behaviour is the hypothesis that tries to explain why some avian species have such elaborate song repertoires for the purpose of territorial defence. The hypothesis takes its name from the 1924 book Beau Geste and was coined by John Krebs in 1977.[1]
Background
The Beau Geste hypothesis which was coined by Krebs in 1977 to explain why various avian species have such large song repertories.[1] The hypothesis discusses that avian species utilize such large song repertories for potentially a number of reasons such as for territorial defence and to test the competition within a new habitat.[2]
The name of the hypothesis comes from the book which was originally published in 1924 "Beau Geste".
Non-avian species
There has been mention of this hypothesis in places such as research into
The Beau Geste hypothesis has also been found to explain vocalizations within some cricket species such as the bush cricket, where males use a wide variety of songs to access the amount of competition which is in a given area.[5] When males are present in an area with a large number of other males their vocal repertories are much smaller than when in an area with only a few males.[5]
