...to consider the consequences of proposed navigational capacities and behaviour and related sensory mechanisms at spatial and temporal scales beyond those observable in the lab or in field experiments. To this end, we developed a modelling framework to assess orientation strategies based on geophysical compass cues, focusing on performance among compass courses on a global scale. The logical extension through enhanced SFB-collaborations is to model true navigation, collective migration of fish and bats versus solitary migratory birds and how migration routes evolve based on input from magnetic sensors.
