Feral cat GPS tracking and simulation models to improve the conservation management of night parrots

چکیده
Context Night parrots (Pezoporus occidentalis) are one of Australia’s most endangered birds, and there is evidence suggesting feral cats (Felis catus) a major cause decline. However, because night currently have restricted distribution, little known the ecology around their remaining populations. This limits development effective management strategies. Aims The aims this study were to understand cat movement habitat selection parrots, then estimate effectiveness possible actions. Methods Research was conducted only confirmed parrot population in eastern Australia. In 2019 2020, we obtained GPS data from nine cats, used step functions assess preferred habitats. Management options simulated based on data, including altering trap numbers layout, changing routes for spotlight shooting (using existing roads, random walking or creating new roads habitats). Key results Feral alluvial riparian habitats avoided rocky woodlands roads. Simulated control efforts more successful if traps placed at ‘pinch points’ where drainage lines converged, created near creek Conclusions move last Australia, travelling through using many shared Targeting areas operations would improve potentially reduce predation impacts parrots. Implications Conservation birds like can be enhanced understanding threats such as develop locally tailored operations.
