Figure 4. — In the zonal model, radii around the focus animal (black) define the type of interaction with other animals: those within d_r (red) are repulsive, those between d_r and (blue) are neutral or aligning, and those between and d_a (green) are attractive. Animals outside of d_a (grey) are not sensed or are ignored.
