Fig. 6From: Hidden Markov models identify major movement modes in accelerometer and magnetometer data from four albatross speciesHeading derived from triaxial accelerometer and magnetometer data streams used to characterize dynamic soaring. a Two segments of heading (in degrees) from different times along a black-browed albatross trip demonstrate varying patterns in soaring flight. b A schematic from Richardson et al., 2018 demonstrates the periodic nature of dynamic soaring. c A polar histogram of the heading data used in panel (a)Back to article page
