Timor Green Pigeon Facing Imminent Extinction, Urgent Conservation Needed

By Published

The Timor Green Pigeon (Treron psittaceus), an endemic bird species of the island of Timor and nearby islets, is critically threatened with extinction. Studies based on over 1,400 field days between 2002 and 2025 show that the global population has plummeted from previous estimates of up to 2,000 individuals to as few as 100-500, mostly confined to Timor-Leste’s Lautem District, especially within Nino Konis Santana National Park. The species is considered functionally extinct in Indonesian West Timor since 2005. The primary threats are hunting for meat and loss of habitat due to deforestation and land conversion. Scientists are advocating for uplisting the pigeon’s conservation status from Endangered to Critically Endangered on the IUCN Red List to prioritize urgent conservation measures involving governments, local communities, and conservation organizations.

Key Facts

  • Scientific Name: Treron psittaceus
  • Endemic Range: Timor Island, with presence also on nearby Rote, Semau, Atauro, and Jaco Islands
  • Population Estimate (2026): Approximately 100 to 500 individuals globally, with likely numbers at the lower end
  • Main Sightings: Concentrated in Lautem District, Timor-Leste; especially within Nino Konis Santana National Park
  • Status in Indonesia: Considered functionally extinct in West Timor since around 2005
  • Primary Threats: Hunting for meat and habitat loss primarily due to deforestation and land conversion
  • IUCN Conservation Status: Currently listed as Endangered; researchers propose uplisting to Critically Endangered based on rapid decline
  • Study Duration: Over 1,400 days of fieldwork conducted between 2002 and 2025
  • Lead Researchers: Dr. Colin Trainor (Charles Darwin University), Alex Berryman (BirdLife International)

Background & Context

The Timor Green Pigeon is a fruit-eating bird endemic to the Wallacea region, which serves as a key biodiversity hotspot lying between Asia and Australia. This pigeon is unique to Timor and its nearby smaller islands, thriving historically in forested habitats. Despite the proclamation of Nino Konis Santana National Park in 2008, which aimed to protect forest habitats in Lautem District, the bird’s population has drastically declined, underscoring the severity of threats such as hunting—a culturally ingrained practice—and ongoing habitat destruction. The species' contraction to increasingly restricted forested areas in Lautem is a strong indicator of ecosystem distress.

Why This Matters for Exams / Exam Relevance

The Timor Green Pigeon exemplifies concepts crucial in environmental science and biodiversity sections of competitive exams: endemic species conservation, effects of anthropogenic pressures like hunting and land conversion, and the role of international conservation frameworks such as the IUCN Red List. Understanding regional biodiversity hotspots like Wallacea provides important context for biogeographical studies. Additionally, the case highlights the intersection of ecology, culture, and conservation policy, topics frequently covered in general studies and environmental science syllabi.

Points to Remember

  • The Timor Green Pigeon is endemic to Timor and a few surrounding islands, highlighting island endemism and vulnerability.
  • Population decline from prior estimates of up to 2,000 individuals to a critically low figure of 100-500.
  • Functionally extinct in Indonesia’s West Timor since 2005, survival depends on Timor-Leste populations.
  • Most remaining individuals found in Lautem District, particularly in Nino Konis Santana National Park.
  • Primary threats include hunting for subsistence and traditional practices, and habitat loss due to forest clearance.
  • Urgent conservation actions are needed, including community engagement and legal protection enforcement.
  • Researchers propose elevating conservation status to Critically Endangered to reflect imminent extinction risk.
  • Research was led by Dr. Colin Trainor and Alex Berryman, published in a May 2026 study in the peer-reviewed journal Oryx.
  • Study spanned over two decades with over 1,400 field survey days, involving comprehensive data compilation including historical records.
