a Instrumented killer whale modelled tracks based on the raw location estimates of the top (red) and bottom (blue) tags. The raw location estimates were processed through a state space model based on a correlated random walk. b Distance between the two modelled tracks for each time hour. The trendline is a loess curve, based on an alpha of 0.75. c Density of the turning angles between consecutive hourly locations. d Density of the step length between consecutive hourly locations
