FeatureDescriptionType
Environment densityFraction of non-ground (vegetated) area within a 2.5 m* radius of a potential locationHabitat Feature
Social densityFraction of all troop mates within a 4.25 m* radius of a potential locationSocial Feature
Sleep site directionDirection of a potential location relative to the sleep site, ranges from −1 (directly away) to 1 (directly toward), fit as interaction with time of dayHabitat Feature
RoadsWhether a potential location is on a road (1) or not (0). Fit as an interaction with whether the baboon’s previous location was on a roadHabitat Feature
Recently-used spaceNumber of other baboons (not including focal individual) that have occupied a potential location within the past 4.5 min*Social Feature
Ever-used spaceWhether a potential location was ever occupied by another baboon (not including focal individual) across the entire datasetBoth
Animal pathsWhether a potential location is on an animal path (1) or not (0), fit as interaction with whether baboon’s previous location was on a pathHabitat Feature
Visible neighborsFraction of other group members visible from a potential location (i.e. direct line-of-sight does not pass through any vegetated areas)Social Feature
SlopeChange in elevation to a potential location from the baboon’s previous locationHabitat Feature
  • *Spatial and temporal scales were determined using maximum likelihood in a preliminary analysis. See Supplementary methods and Appendix 1—table 1 for further details.
