There are folks in Jakarta, Indonesia that raise and train roosters to mimic the sound of human laughter so they can enter them in a very competitive ‘laughing cock’ contest. In this video from 2011 by Barcroft Media, you can listen to the birds ‘laughing’ at the contest.
A total of 187 chickens took part in a laughing contest during the exhibition of flora and fauna in Jakarta, Indonesia on 16 July 2011. Contestants were divided into four categories; a category for novice chickens under the age of 1, a category for chickens with a routine or crowing sound, a category for chickens with a unique sound and a category for chickens and a category for chickens with low voices, and these chickens are seen as the most prestigious and most expensive (and can be sold for up to tens of thousands of US dollars!).
