Resum:Predators are an essential component of past and present ecosystems and trophic networks. In addition,
their role as bone bio-accumulators may at least partly determine the richness of fossil sites. Prior to
human arrival, terrestrial mammals were absent from the Pityusic Archipelago (Eivissa and Formentera
islands, Western Mediterranean Sea), a feature that represents an ecological singularity in the
Mediterranean islands. The diurnal and nocturnal predatory bird guild from the Upper Pleistocene and
Holocene of the Eivissa Island is approached here through the study of Accipitridae, Falconidae and
Strigidae from Es Poua` s, an extraordinarily rich fossil site that provided more than two thousand bones of
birds belonging to these three families. The importance of each species as bio-accumulator and a
comparison with current fauna are outlined.
