Thermal drone observations capture fine‐scale population decline of short‐tailed shearwaters
Remote Sensing in Ecology and Conservation, Volume 11, Issue 6, Page 773-789, December 2025.Researchers used thermal drone technology to monitor short‐tailed shearwater colonies in Tasmania from 2019 to 2024, discovering a concerning 27% decline in chick numbers during this period. The study estimates that the global population of these seabirds has dropped dramatically by 41% since 1985, falling from 23 million to approximately 13.5 million ...
