| Summary: | 1. Human activities can influence the movement of organisms, either repelling or attracting individuals depending on whether they interfere with natural behavioural patterns or enhance access to food. To discern the processes affecting such interactions, an appropriate analytical approach must reflect the motivations driving behavioural decisions at multiple scales. 2. In this study, we developed a modelling framework for the analysis of foraging trips by central place foragers. By recognising the distinction between movement phases at a larger scale and movement steps at a finer scale, our model can identify periods when animals are actively following moving attractors in their landscape. 3. We applied the framework to GPS tracking data of northern fulmars Fulmarus glacialis, paired with contemporaneous fishing boat locations, to quantify the putative scavenging activity of these seabirds on discarded fish and offal. We estimated the rate and scale of interaction between individual birds and fishing boats ... : Fulmar tracking dataThe spreadsheet contains the fulmar tracking data used for the study, collected on Eynhallow (Scotland) in July 2009. The data were filtered and interpolated at a 10-minute resolution using R, as described in the paper. The data set includes: the bird and trip ID numbers, the longitude and latitude coordinates of a bird at each time step of a trip, the corresponding date and time, the step length (in degrees), the bearing (measured from 0 radians), and the closest boat's longitude, latitude and distance (in km) from the bird.Fulmar_trackingData.csv ... |
