Tune into Nature with Karthic

Cryptic Birds and How to find them?

Tune into Nature with Karthic

Show Notes

In the southern corner of New Zealand, a team is working to detect secretive, cryptic wetland birds… using sound.

Matuku Hūrepo Australasian Bitterns are so shy and cryptic, that they are rarely seen. They are wetland birds and with a 90% loss of wetland area in New Zealand, their populations are in steady decline. A collaborative project is underway in the Otago region to understand more about these birds by detecting them using acoustic recorders.
