OS-Prey (Omnibus study of prey) V2

The diet composition of a predator is a direct reflection of its role in a food web, resulting from interactions with prey species. Raptors (including hawks, eagles, owls, and falcons) are ubiquitous predators with diverse diets. We present a database of over 2000 raptor diets, representing 130 raptor species from across the world. The database comprises published records of raptor diets from pellets, prey remains, direct or photographic observations, prey DNA, and raptor gut contents. For each diet, we present the amounts and proportions of consumed prey as well as metadata such as location, habitat, and season.
