On Indonesia’s Seram Island, the Huaulu Indigenous community has adapted a centuries-old coming-of-age ritual to reduce hunting pressure on the endangered salmon-crested cockatoo.
asserted
community → adapt → cockatoo
The Cidaku ceremony marks young men’s transition to adulthood and traditionally involved hunting the cockatoo for its distinctive crest feathers, which are worn in a ceremonial headdress called the puheliam.
asserted
which → mark → headdress
A new study in the Journal of Ethnobiology titled
Sacred Rituals and Endangered Birds: A Biocultural Approach to Cockatoo Conservation on Seram Island, Indonesia, documents how the community, working with researchers and conservation authorities, agreed to replace hunted feathers with naturally moulted ones collected from rescue and rehabilitation centres and zoos.
asserted
community → title → centres
The change allows the ceremony to continue while removing the need to kill wild cockatoos for feathers.
asserted
ceremony → allow → feathers
Researchers say the approach illustrates how conservation can work with Indigenous cultural traditions rather than simply imposing outside restrictions.
asserted
conservation → say → restrictions
However, they stress that the arrangement addresses only one source of pressure, while illegal wildlife trafficking and habitat loss remain much larger threats to the species.
asserted
trafficking → stress → species
Why the Cidaku ceremony traditionally used salmon-crested cockatoo feathers
For generations, young Huaulu men demonstrated their passage into adulthood through the Cidaku ritual, in which salmon-crested cockatoo feathers formed an important part of the ceremonial puheliam headdress.
asserted
feathers → use → headdress
The symbolism is deeply rooted in Huaulu spiritual traditions: the community views the forest as a living realm inhabited by powerful spirits, and hunting is understood as a sacred exchange rather than simply a means of obtaining an animal or its feathers.
asserted
hunting → root → animal
The cockatoo became one of the ritual’s important animal targets after earlier traditions associated with head-taking were suppressed by colonial authorities and Christian missionaries in the early 20th century.
asserted
traditions → become → century
The research describes the subsequent adaptation as part of a much longer history of cultural change, with the ritual retaining its spiritual significance while its specific practices evolved.
asserted
practices → describe → significance
Why conservation laws created a conflict with the tradition
The salmon-crested cockatoo (Cacatua moluccensis) is endemic to the Maluku Islands and is classified as Endangered on the IUCN Red List.
asserted
cockatoo → create → List
Its populations have declined sharply, with researchers identifying demand from the illegal wildlife trade as the primary driver, alongside habitat loss from logging and agriculture.
asserted
researchers → decline → logging
The species has disappeared from the nearby islands of Haruku, Saparua and Nusa Laut, leaving Seram as its main remaining stronghold.
asserted
species → disappear → stronghold
Indonesian law also gives the bird strict national protection, prohibiting its capture, possession or killing, including for ceremonial purposes.
asserted
law → give → purposes
That created a difficult conflict for the Huaulu: enforcing wildlife law protected the cockatoo but could also threaten a ritual central to the community’s cultural and spiritual identity.
uncertain
enforcing → create → identity
The researchers therefore explored whether the material used in the ceremony could change without removing the ceremony’s deeper meaning.
uncertain
material → explore → meaning
Researchers worked with the Huaulu community in two main periods, from March to November 2019 and again from July 2024 to May 2025 after the COVID-19 pandemic interrupted the project.
uncertain
pandemic → work → project
They interviewed community members, surveyed households and consulted traditional leaders, hunters and conservation authorities.
asserted
They → interview → leaders
The resulting agreement uses naturally moulted cockatoo feathers obtained through rescue centres, rehabilitation facilities and zoos instead of feathers taken from hunted birds.
asserted
agreement → result → birds
The study describes this as a form of symbolic substitution: the feathers retain their cultural and ceremonial importance, while the hunt itself is no longer necessary to obtain them.
asserted
hunt → describe → them
The agreement also revives traditional forest taboos and customary rules against commercial wildlife exploitation.
asserted
agreement → revive → exploitation
Researchers caution, however, that this solution does not by itself resolve the cockatoo’s wider conservation crisis.
asserted
solution → caution → crisis
Illegal wildlife trafficking and habitat loss remain major threats, meaning long-term protection will require both community-led conservation and broader action against commercial exploitation.
asserted
protection → remain → exploitation
