The data were collected using GPS loggers deployed on incubating and/or chick-rearing birds. Data were partitioned into non-flight (i.e. foraging and resting), relevant to displacement effects, and flight, relevant to collision risk (barrier effects are relevant to both categories). The data required processing in two steps. First, all locations recorded at the colony were removed from the data set. Second, locations recorded during flights were partitioned from locations recorded during non-flight periods (which constitute foraging or resting). This partitioning was achieved by plotting a histogram of speeds, which was typically bimodal with the different peaks representing flight and non-flight respectively.
