The BBC's Natural History Unit also featured the kakapo, including a sequence with Sir David Attenborough in "The Life of Birds". It was also one of the endangered animals Douglas Adams and Mark Carwardine set out to find for the radio series and book "Last Chance to See". An updated version of the series has been produced for BBC TV, in which Stephen Fry and Carwardine revisit the animals to see how they are getting on almost 20 years later, and in January 2009, they spent time filming the kakapo on Codfish Island. Footage of a kakapo named Sirocco attempting to mate with Carwardine's head was viewed by millions worldwide, leading to Sirocco becoming "spokes-bird" for New Zealand wildlife conservation in 2010. Sirocco became the inspiration for the party parrot, a popular animated emoji frequently associated with the workflow application Slack.
