“Track Days” is a measure of each animal’s detection period from the day of the first detection to the day of the last detection. “RI” stands for residence index and is calculated as the number of days detected in the array divided by the number of days between first and last detection. Individuals simultaneously fitted with a satellite tag are marked by an asterisk (*)
