Illustrative representation of several natal dispersal processes and comparative graphical representation of the estimated point of dispersal from simulated data calculated using method 12. Left panels are pictographic representations of a) natal dispersal of an individual emigrating and settling in a single movement from the natal home range to its own breeding home range, b) natal dispersal where emigration is a single movement away from the natal home range followed by the formation of a transience home range prior to a single movement to its own breeding home range, c) natal dispersal where emigration is preceded by prospecting forays and emigration is a single movement to its own breeding home range, d) natal dispersal of a seasonally territorial species where an individual uses an extended home range outside of the breeding season, overlapping with the natal home range before making a distinct movement to a new area that contracts during the territorial season into its own breeding home range, e) natal dispersal with a distinct movement between one social group’s home range and a new social group’s home range. Right panels are a graphical representation of simulated data from an individual from each corresponding 5 strategies. All individuals emigrate after 75 time units of a 150 time unit long follow. Points - occupation of natal home range at each time point (1 = in natal home range, 0 = outside of natal home range), solid line – diffP see Methods for details of calculation (using 20 day sliding window), vertical dotted line – time = 75 and individuals emigrate.
