  1. The collars were active for varying durations between October 2014 and April 2017. Models were generated using mixed-effects logistic regression models with a random intercept specified for each buffalo and herd. The continuous covariates were standardized to improve model performance and allow for comparison of effect sizes across variables. A priori models were developed for each season and then ranked by model weight using the Akaike Information Criterion. ELEV (m) = elevation in meters, RUGGED = ruggedness, DISTRIV (m) = distance to nearest river in meters, V_OP_TR_15_40% CC = very open trees with 15–40% crown cover, OP_TR_40_65% CC = open trees with 40–65% crown cover, TR_SHR_SAV = trees and shrub savannah, OP_SHR_40_65% CC = open shrubs with 40–65% crown cover, CL_OP_WOODVEG = closed to open woody vegetation (thicket), SHR_SAV = shrub savannah, OP_CL_HERBVEG_TEMP_FL = open to closed herbaceous vegetation on temporarily flooded land, V_OP_SHR_15_40% CC = very open shrubs with 15–40% crown cover, OP_CL_SHR_TEMP_FL = open to closed shrubs on temporarily flooded land, CL_TR_TEMP_FL = closed trees on temporarily flooded land, CL_SHR = closed shrubs, IS_RF_HERB_CRP = isolated (in natural vegetation or other) rainfed herbaceous crops, SCAT_RF_HERB_CRP = scattered rainfed herbaceous crop, CL_TR = closed trees, SE = standard error, Ref = reference category for categorical variables
