Description

Little is known about the ecology of Christmas Island’s 2 endemic apex predators – the Christmas Island hawk-owl (Ninox natalis) and Christmas Island goshawk (Accipiter fasciatus natalis). This impedes the effective conservation management of these threatened and ecologically important species.

The hawk-owl (boobook) and goshawk are integral parts of the island’s ecosystem. Christmas Island as a priority place under the Australian Government’s Threatened species action plan 2022–2032, and the goshawk is listed as a priority species under the same plan.

To conserve these species, this project is collecting new data on their population sizes, habitat preferences, diet and genetic diversity.

This information is critical for supporting effective management of the 2 species. In the case of the hawk-owl, it’s also relevant to understanding the importance of hollow-bearing trees for some other bird species on Christmas Island. For the goshawk, this information will help to resolve its taxonomic relationship with other Accipiter species.

This project is combining field-based and lab-based methods to determine the status, health and critical habitat requirements of these species and developing robust designs for monitoring population trends. Results will inform the spatial targeting of habitat management on Christmas Island, the management of invasive prey species (i.e. black rats), and direct conservation interventions for the 2 raptors.

Key research areas

To address the challenges on conserving apex raptor species on Christmas Island, this project is:

  • collecting data on the distributions, abundances, demographics, individual health, spatial ecology diet and genetics of the Christmas Island hawk-owl and goshawk
  • establishing robust monitoring design
  • providing important insights into how changes in populations of other species might affect these predatory birds
  • determining how urgently conservation actions may be required.

Pathway to impact

This project will support the long-term conservation of Christmas Island’s endemic raptors by:

  • providing a clear understanding of the population status, health and habitat needs of the Christmas Island goshawk and hawk-owl
  • guiding targeted habitat protection, restoration and invasive species management in a national priority area
  • strengthening long-term conservation through robust monitoring designs that detect population change early and support adaptive management.
