Spotlight on the Matuku: Hosting Wendy Ambury from the Love Bittern Project

At Okarito Boat EcoTours, we were thrilled to recently host Wendy Ambury from the Love Bittern Project. Wendy’s passion and deep knowledge of the matuku (Australasian bittern) brought a new level of appreciation for this cryptic and elusive bird.
The matuku is a type of heron, but vastly different from the striking and elegant kotuku (great white heron). Preferring the dense cover of reeds in wetland habitats, bitterns are masters of camouflage. If startled, they can launch themselves into flight with surprising speed, landing moments later among the reeds where they blend seamlessly into their surroundings by pointing their bill skyward, mimicking the reeds themselves.

​Protecting a Disappearing Species

Despite their remarkable adaptations, the matuku is in serious trouble. Wetland loss in New Zealand is a major factor contributing to their decline, with over 90% of the country’s wetlands having been drained or degraded. Remaining wetlands often lack the abundant food sources these birds need, leaving many matuku at risk of starvation.
During her visit to Okarito, Wendy was delighted to observe the intact wetlands of the lagoon—prime habitat for the matuku. While we didn’t spot a bittern during her tour, she was thrilled to hear the distinctive booming call of a male echoing across the wetland. This haunting sound is one of the few ways to confirm their presence, as they are rarely seen.

​A Call to Protect Our Wetlands

Wendy’s visit was a poignant reminder of the urgent need to protect and restore New Zealand’s wetlands. Without these vital ecosystems, the future of the matuku is at serious risk. At Okarito, we are fortunate to host a habitat that provides a haven for this remarkable species.
And yes, while sightings are rare, we do occasionally see matuku during our tours! In November, a lucky group had an unforgettable encounter with a large male bittern right beside the boat—a truly memorable experience.

​Join the Effort

We all have a role to play in preserving wetlands and the unique species that depend on them. By protecting these habitats, we can give the matuku a fighting chance to thrive once more in New Zealand.
If you’d like to learn more about the matuku, the Love Bittern Project, or our wetlands, join us on an Okarito EcoTour. You might just hear the booming call of a matuku or, if you’re very lucky, spot one in its natural habitat. Together, let’s celebrate and protect the incredible biodiversity of Okarito Lagoon.
