Which process initiates navigation following displacement beyond foraging territory relying purely on scent?

💡 Explanation

Homebound salmonid migration uses olfactory imprinting where river-specific scents trigger recall; navigation, not just random searches, begins because receptor activation elicits directed movement toward natal streams, therefore imprinting orients them, rather than localized scent gradients at displacement.
