The 2019 kākāpō breeding season was one for the record books, but it had more than its fair share of problems, including the fact that more than half of the eggs laid were infertile.
It’s an ongoing issue, not helped by the birds’ low genetic diversity. The Kākāpō Recovery team are using artificial insemination as part of their genetic matchmaking efforts, and have turned to a drone to speed the process of sperm delivery.
Join Alison Ballance on an audio adventure through the biggest kākāpō breeding season on record.
