摘 要：Cutting-edge technologies are extremely useful to develop new workflows in studying ecological data,particularly to understand animal behavior and movement trajectories at the individual *** parental care is a well-studied phenomenon,most studies have been focused on direct observational or video recording data,as well as experimental ***,what happens out of our sight still remains *** high-frequency GPS/GSM dataloggers and tri-axial accelerometers we monitored 25 Bonelli’s eagles Aquila fasciata during the breeding season to understand parental activities from a broader *** used recursive data,measured as number of visits and residence time,to reveal nest attendance patterns of biparental care with role specialization between *** data interpreted as the overall dynamic body acceleration,a proxy of energy expenditure,showed strong differences in parental effort throughout the breeding season and between ***,males increased substantially their energetic requirements,due to the increased workload,while females spent most of the time on the ***,during critical phases of the breeding season,a low percentage of suitable hunting spots in eagles’territories led them to increase their ranging behavior in order to find food,with important consequences in energy consumption and mortality *** results highlight the crucial role of males in raptor species exhibiting biparental ***,we exemplify how biologging technologies are an adequate and objective method to study parental care in raptors as well as to get deeper insight into breeding ecology of birds in general.
