Abstract

We present the first report of the trophic ecology of Northern Crested Caracara Caracara cheriway in Ecuador, from the analysis of pellets collected at Jambelí archipelago, province of El Oro. The most representative prey were mammals (39.4%), followed by insects (29%), reptiles (13.2%) and birds (10.5%). Mammals contributed the highest percentage of biomass (83.3%), followed by reptiles (8.5%) and birds (7.3%). Although C. cheriway is a highly opportunistic generalist consumer, its diet was mainly constituted by living prey in our study area, leaving carrion consumption as a complementary feeding strategy.
