| Summary: | 1. Animal populations are often comprised of both foraging specialists and generalists. For instance, some individuals show higher foraging site fidelity (spatial specialisation) than others. Such individual differences in degree of specialisation can persist over timescales of months or even years in long-lived animals, but the mechanisms leading to these different individual strategies are not fully understood. 2. There is accumulating evidence that individual variation in foraging behaviour is shaped by animal personality traits, such as boldness. Despite this, the potential for boldness to drive differences in the degree of specialisation is unknown. 3. In this study, we used novel object tests to measure boldness in black-legged kittiwakes (Rissa tridactyla) breeding at four colonies in Svalbard, and deployed GPS loggers to examine their at-sea foraging behaviour. We estimated the repeatability of foraging trips, and used a hidden Markov model to identify locations of foraging sites in order to quantify ... : Harris_etal_2019_boldnessSiteFidelity_JAE_data_archiveThis data package contains (i) data from personality tests used to calculate individual boldness estimates, (ii) foraging trip distances, durations and ranges used to estimate foraging trip repeatability, (iii) locations of foraging sites used to test for personality-dependent spatial partitioning, and (iv) estimates of individual foraging site fidelity used to test for a relationship between site fidelity and boldness.
