[1] 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.
[3] The book tells the story of three English brothers which all enlisted in the French Foreign Legion and ended up in a desert battle against a Tuareg army.
They were greatly outnumbered, and in order to create the illusion that they had more men than they actually had, they took whatever dead soldiers they could find and propped them up along the walls of the fortress.
[citation needed] There has been mention of this hypothesis in places such as research into amphibian vocalizations in the Boophis madagascariensis, an endemic species of tree frog found in Madagascar,[4] where the Beau Geste hypothesis is used to give one explanation of why the species has such a large vocal repertoire.
