Migrating Eastern North American monarch butterflies use a time-compensated sun compass to adjust their flight to the southwest direction. To understand how it is implemented on a neural level we derived a neural circuit model, which integrates azimuthal and circadian signals to correct flight direction.
The model demonstrates an integration mechanism, which produces robust trajectories reaching the southwest regardless of the time of day and includes a configuration for remigration.
