The first ever successful captive holding program for Palauan Megapodes has concluded with a release of the birds to their home, Ngeanges Island. The success of the captive holding program is a major milestone for the restoration of the ecosystem on Ngeanges, and paves the way for future restoration work in Palau’s stunning Rock Island Southern Lagoon.
The story began in May 2016 when we collaborated with the Koror State Department of Conservation and initiated the Ngeanges rodent eradication project. To safely carry out operations, we needed to house the island’s sensitive native megapodes. To this end a planning committee was formed including Island Conservation, Palau Conservation Society, the Balau National Museum, and the Palau International Coral Reef Center. The group designed and built aviaries on a nearby island with careful consideration to create a habitat these birds would feel comfortable in. The Conservation Officers worked days and nights to capture megapodes from Ngeanges; they used a variety of different methods to safely trap the birds. Once they were transported across the lagoon on boat and placed in their aviaries, the birds were monitored and fed by the Koror State Rangers who worked around the clock to ensure the preservation of the Rock Islands.
During post-implementation monitoring, and on subsequent visits by our partners in Palau, the Department of Conservation and the Belau National Museum observed an apparent increase in the activity of megapodes on Ngeanges. There was no shortage of megapode sightings, and observers noted what they perceived to be more abundant signs of megapodes scratching through leaf litter and nest mound building activity. Although it is still too soon to confirm the long term success of the rat removal, these sightings could very well be due to the lack of competition from the invasive rats that abounded on the island only months before.

Megapodes are fascinating birds; the subspecies we are working with is endemic to Palau and listed as Endangered. The name is descriptive of the massive size of their feet and legs in comparison to the size of their body. They use their powerful feet to build giant nest mounds on the forest floor by “kicking” soil and leaf litter into a pile that sometimes exceeds six feet in height!
The females lay and bury their eggs in a hole that they dig into the center of the mound. The egg is then incubated by the heat produced by the microbial decomposition of the leaf litter. When the chicks hatch, they dig their way out of the mound and are on their own to fend for themselves. They must forage for food alone and one day build nest mounds of their own.
Megapodes share their island home with a variety of wildlife; the forest is flush with songbirds, Palau Fruit-doves, terns, fruit bats, Emerald Tree Skinks, and the occasional nesting sea turtle.This project marks a huge success for Island Conservation and our work in Palau in both restoration and capacity-building.

We are excited to keep the momentum going and we are already making progress towards planning a rat eradication on the main island of Kayangel Atoll in the North of Palau.
