Scientists are getting creative to save this muppet-faced, flightless parrot

https://www.nationalgeographic.com/animals/2019/03/endangered-kapako-breeding-technology/?cmpid=org=ngp::mc=crm-email::src=ngp::cmp=Editorial::add=Animals_20190307::rid=27536634995

Priceless quote (emphasis added): '...a team of scientists, rangers, and volunteers are working around the clock during the current breeding season, using 3D-printed smart eggs, activity trackers, and a sperm-toting drone nicknamed the "cloaca courier"...'


A female kakapo sits with her chick on Whenua Hou/Codfish Island in New Zealand. Nocturnal and flightless, these unusual parrots are critically endangered, with only 147 adults left in the world.
