Boxplots representing foraging trip parameters a) maximum distance (km), b) path length (km), and c) trip duration (h) of incubating Kelp Gulls from six South African colonies (DW = Dwarskersbos, MA = Malgas Island, JU = Jutten Island, ST = Strandfontein, KE = Keurbooms, SW = Swartkops) in 2017–2018. The boxplots show the median values (band inside box), the 25th and 75th percentiles (box), the smallest and highest value within 1.5 times interquartile range (whiskers) and outliers (dots). N represents the number of trips per colony and boxes and letters above with different shades of grey are significantly different from Tukey test results
