GPS and PTT locations of incubating and chick-brooding Laysan (n = 114, panel a) and black-footed (n = 118, panel b) albatross breeding at Tern Island. Tracks used for this figure were collected for this study and a concomitant long-term tracking study from 2006, 2009, 2010, 2011 and 2012. Tracks were interpolated to 1 position every 5 h. Incubating birds of both species spend the majority of time in higher latitudes in the North Pacific Transition Zone as well as coastal locations around the Pacific Rim. Clear spatial segregation between the species occurs during the incubation stage (focal range overlap of 50.8 % [24]) but spatial segregation breaks down during the brood-guard stage (focal range overlap of 75.4 % [24]). Tern Island is indicated with a star
