Maleo Research


Investigating what we need to know to recover the Critically endangered maleo


AlTo’s maleo research program is aimed at learning essential facts about the maleo’s biology and ecology that must be discovered in order to ensure the maleo’s long-term survival in a human-dominated landscape.

AlTo’s research program began in 2017, and is being carried out in collaboration with Indonesian maleo experts and local people, including former poachers, under a research permit from BRIN (Indonesian National Research and Innovation Agency). It includes the following components:

 -A Sulawesi-wide survey of all known active maleo nesting grounds (manuscript currently in preparation)

 –A systematic assessment of the drivers of maleo nesting ground decline
