Journal of Animal Ecology, Volume 93, Issue 9, Page 1176-1191, September 2024.During fall migration, avivorous raptors and avian prey co‐occur across space and time. We used a novel approach—combining eDNA metabarcoding and eBird data—to investigate predator–prey interactions between an avivorous raptor and co‐occurring avian prey species. This approach revealed prey availability and traits influence raptor‐songbird interactions
