%X The kagu (Rhynochetos jubatus) is an iconic endemic flightless bird from New Caledonia, red-listed as endangered according to the International Union for Conservation of Nature (IUCN) criteria. Feral cats are among the most successful and damaging invaders for island biodiversity. They have been directly responsible for the extinction of numerous birds worldwide, especially small- and medium-sized flightless species. Our study evaluates the feral cat threat to the kagu by analysing 772 cat scats from the two main sites housing major remaining populations (eight quarterly sampling sessions conducted per site over 2 years). Surprisingly, we detected no predation evidence against this endangered species (including chicks) although it falls within the cats' prey size range and exhibits life-history traits typical of island endangered naive birds. We recommend a multi-species approach to invasive mammal management to mitigate direct and indirect pressures against remaining kagu populations.
