🌿 HELP SUPPORT OUR AMAZING NATIVE BITTERN! 🌿
Have you heard the deep “boom” of a matuku-hūrepo (Australasian bittern) around the Rotorua lakes and wetlands?
The last known flock in the Rotorua district was seen rising from raupō, but it is believed that bittern are still using wetlands and freshwater habitats around our lakes.
How many are still out there is unknown.
Matuku-hūrepo are just one step from extinction, with the national population thought to be fewer than 1,000 birds. With numbers this low every bittern counts.
We’re supporting Love Bittern / Community Conservation Action Aotearoa in raising awareness locally and encouraging people to take part in The Great Matuku-hūrepo Muster, a nationwide synchronised count where people listen for and record the distinctive booming call of male bittern.
Last year, a small group of people and a couple of recorders detected bittern near Lake Ōkāreka, and two young bittern were also sighted near Lake Rotoehu.
Imagine what we might discover with more people listening!
Matuku Mingle:
Saturday 10 October | 2–4pm�Boyes Beach�Postponement: Sunday 11 October
Come along for an informal afternoon to learn more about bittern, meet others interested in helping, and, weather permitting, enjoy a walk and talk through nearby restored wetlands. Training will also be available for those interested in taking part in the Muster.
☕ Bring a drink and a plate to share for afternoon tea.
🎧 The Great Matuku-hūrepo Muster:
The Muster is your chance to help find out where bittern are still living around our lakes and wetlands by listening for their booming calls and recording what you hear.
If you’re a local who would like to learn more or help with the count, please check out the event details and get in touch via the website link below. You don’t need to be a bittern expert, just a willingness to listen and help!
Every pair of ears could help with the discovery of another matuku-hūrepo. 💚
