Table 2. Cumulative displacement moved by flying-foxes among roosts in time-periods of 1–30 weeks duration.

Time-period (weeks)	N	N = 0 km	Mediankm	Meankm (SD)	Rangekm
1	333	201	0	33 (70)	0–576
5	64	9	111	161 (166)	0–690
10	31	2	260	316 (236)	0–821
20	13	0	618	584 (381)	120–1121
30	5	0	821	798 (217)	489–1059

Cumulative displacement is the sum of all sequential distances between consecutive recorded roost sites during each time-period.

N: number of ‘timed movements’ in each time-period (see text).

SD: standard deviation.
