total cumulative distance travelled | the total sum of the lengths of the recorded trajectory measured in metres using great circle distances between all consecutive recorded locations | *D*_{tot} |

maximum distance | maximum displacement or the maximum distance between any two locations the birds were observed | *D*_{max} |

average distance | mean of all step lengths measured in metres from consecutive locations | *d*_{seg} |

mean speed | mean of the step length in metres divided by the time lag in seconds | *v*_{seg} |

maximum speed | maximum value of distance covered between two locations divided by time | *v*_{max} |

mean coefficient of the first passage time (FPT) | the FPT measures the time an individual needed to cross a circle of a given radius *r*. It is a cross-scale analysis of the movement pattern, where the slope of the log of the mean of FPT against the log of the radii of the circles should be about 2 for Brownian motion. Lower values indicate facilitated diffusion, or subdiffusive or advective movement, referring to non-random and thus, more or less, directional movement. Higher slopes indicate superdiffusive or impeded diffusion | FPT_{coef} |

intercept of the mean FPT | the intercept of the correlation of the log of the radii and the FPT is an indicative of the most basal movement characteristic, or the tendency to move irrespective of scaling effects (innate movement) | FPT_{int} |

dispersion factor of a Brownian bridge based on the trajectory | movement can be described by a conditional Brownian motion where an animal moved between known locations in a conditional Brownian fashion, corresponding to a two-dimensional Gaussian process, with a certain variance or dispersion factor (*h*). The higher the estimated variance, the more erratic the movement was and more deviance around the straight line connection is to be expected | *h* |

area of a minimum convex polygon | the area that the animal used according to a minimum area polygon containing all observed locations | MCP |
