Perceiving actual heading is detrimental to migration success in a turbulent flow. (a–d) Heatmaps of the median arrival time relative to an individual in the absence of flow, averaged over 25 realizations, for the [FI], [FA], [NI] and [NA] models, respectively. All simulations are in a turbulent flow environment. The grey line indicates the region expanded in figures (e,f). (e,f) The median arrival time relative to the solo navigator case for a range of lower flow strengths. Grey annotations indicate the time taken relative to a solo navigator in flow. The colourbar is shared across all axes and figure 5.
