Example: Kakapo[]

The Kakapo is a type of bird, more specifically, a parrot, and one of the rarest parrots in the world according to Kakapo Recovery. They do not fly, they are the heaviest parrot in the world, found in New Zealand, and they use a mating boom which can be heard for kilometers.

Their breeding behaviors are unique-males can inflate their bodies like a balloon and send a low, boom noise to attract females. Males congregate (in a lek), to compete for females (usually in December).
