Final, pruned classification trees of six main behaviours of observed geese as calculated by accelerometer statistics. a Classification tree for backpack tags with a legend of cross-validation success rates for each behaviour separately and an overall value. b Same as a, but for neckband tag data. The acceleration statistics used in the analyses are: pitchX—body angle along x-axis, pitchZ—body angle along z-axis, rollY—body angle along y-axis, mdbaX/mdbaY/mdbaZ—maximum dynamic body acceleration along the x-/y-/z-axes, odbaX/odbaY/odbaZ—mean dynamic body acceleration along the x-/y-/z-axes, odba—overall dynamic body acceleration (sum of the previous), dpsX/dpsY/dpsZ—maximum power spectral density of dynamic acceleration along x-/y-/z-axes, fdpsX/fdpsY/fdpsZ—frequency at the maximum power spectral density along the x-/y-/z-axes (for more explanation, see [73])
