From: When do young birds disperse? Tests from studies of golden eagles in Scotland
Determining the point of emigration for a range of illustrative eagle behaviours (see Table1). The vertical dotted line denotes on all panels the calculated timing of dispersal using Method 12. Upper panel: points - occupation of natal home range (natal home ranges defined using the PAT model of golden eagle home ranges) at each time point (1 = in natal home range, 0 = outside of natal home range); solid line – diff P see Methods for details of calculation. Lower panel: solid line – distance from the nest. Different observed emigration behaviour; a) no pre-dispersal excursions, b) single pre-dispersal excursion, c) many pre-dispersal excursions, and d) drifter. For the full range of individuals see Additional file 2.
