Status of the Endangered Yellow Chat Epthianura crocea tunneyi on the western South Alligator River floodplain, Kakadu National Park

A significant decline in the population of the Endangered Yellow Chat (Epthianura crocea tunneyi) subspecies on the western South Alligator River floodplain, Kakadu National Park, was observed between 2004 and 2014. While the 2004 survey recorded 65 individuals across five areas over two days, the 2014 survey, conducted over four days and nearly 40 hours, detected only 27 Yellow Chats in a single area, suggesting a potential long-term population decrease. The study employed intensive field surveys during the late dry season (September–October) to compare habitat use and feral animal impacts between the two periods. Feral pigs (Sus scrofa) were noted as a significant threat, causing damage to wet floodplain areas. The findings underscore the need for comprehensive monitoring across all floodplains within the subspecies' range to assess overall population status and inform conservation strategies.
