Figure 6.

The tracks of four birds, two male and two female, with successive points joined by lines (noting that there may be periods of missing data between two successive points, particularly around the equinoxes). The points are coloured red, green and blue, with respect to their posterior probability of classification into one of three classes using the supervised classifier. Red, summer feeding; blue, winter feeding; green, migration. (a) FR53237 male, (b) FB22795 female, (c) FP52700 female, (d) FC83751 male.
