Jacko is an Australian informal nickname for the laughing kookaburra (Dacelo novaeguineae), one of Australia's most iconic birds, famous for its distinctive call that sounds uncannily like loud human laughter. The nickname follows the Australian tradition of giving birds and animals friendly, shortened nicknames — similar to 'maggie' for magpie or 'cockie' for cockatoo. The kookaburra's call is so strongly associated with Australia that it is a standard sound effect in Hollywood films to indicate jungle settings worldwide.
Every morning jacko would start up at dawn, and after a few days you stopped even noticing it.
