This evening Radio NZ rebroadcast a 2016 interview between host Jessie Mulligan and sound archivist Sarah Johnston, about the only recording we have of what the extinct huia bird sounds like.
We lost the huia in the early 1900s, before recording equipment was available, but what we do have is a recording from the late 1940s of Hēnare Hāmana mimicking the calls of the male and female huia. Some North Island Māori were expert at making huia calls, used to lure the birds in to catch them (in part for their valued feathers). Hēnare had been part of a (failed) expedition into the Ruahine Ranges around 1900 to try and catch huia to bring them into captivity to try and prevent their extinction.
While RNZ doesn't have the interview on its website "due to copyright restrictions", the original recording by Hēnare Hāmana is available below on the website of Ngā Taonga Sound & Vision.
It's sad but worth a listen. We came so close to still having these remarkable birds around.
