Rediscovery of the Manumea: Hope for the Last Living Dodo Relative

A recent field study conducted by the Samoa Conservation Society (SCS) has confirmed multiple sightings of the manumea (Didunculus strigirostris), a critically endangered bird often referred to as the "little dodo." This marks the first series of confirmed sightings in over a decade, occurring between October 17 and November 13, 2023, in the remote Uafato rainforest on Samoa's island of Upolu. The discovery has reignited hope among conservationists, as the manumea was long presumed on the brink of extinction. Moeumu Uili, a project coordinator with SCS, expressed concern about the bird's elusive nature, stating, “What happens if we can’t find the bird? Does that mean the manumea is no more?”

The manumea faces significant threats from habitat loss, hunting, and invasive species, particularly feral cats and rats, which have become major predators. Joe Wood, manager of International Conservation Programs at the Toledo Zoo, emphasized the catastrophic impact of these invasive species, noting that they not only prey on the manumea but also disrupt the ecosystem by decimating native invertebrates and seeds that the bird relies on for food. Despite awareness campaigns and hunting bans, the manumea remains critically endangered, necessitating urgent action to control invasive species and restore its habitat.

Efforts to conserve the manumea include expanding invasive species management programs and utilizing innovative technologies. The SCS is developing an app to identify the manumea’s call, which will aid in tracking and population estimates. Additionally, biobanking initiatives are being explored to preserve biological samples for potential captive breeding or genetic rescue. Organizations like Colossal Biosciences, known for their controversial de-extinction projects, are indirectly supporting manumea conservation by funding related initiatives.

The successful sightings of the manumea were made possible through international collaboration and local knowledge. The Uafato community, along with rangers and volunteers, played a crucial role in the search efforts. The SCS has acknowledged the contributions of various organizations, including Birdlife International and the International Union for the Conservation of Nature’s Pigeon and Dove Specialist Group, highlighting the collective effort required to protect this national symbol of Samoa.

While technological interventions offer promising avenues for conservation, some experts caution against relying solely on high-tech solutions. Nic Rawlence, an evolutionary biologist at the University of Otago, warned that genetic rescue efforts are futile without addressing the ecological infrastructure necessary for the species' survival. He stated, “It still comes down to the grunt work of predator control, habitat restoration, translocation.”

The recent sightings of the manumea provide a fragile but significant opportunity to save a species once thought lost. As conservationists work to protect this unique bird, the situation underscores the importance of immediate action to address the threats it faces. The manumea's survival is not only vital for biodiversity but also serves as a reminder of the delicate balance between human impact and the preservation of natural ecosystems.
