Which outcome occurs when a migratory bird relies solely on olfactory maps during a magnetic reversal event?

💡 Explanation

Disrupted homing occurs because olfactory map navigation becomes unreliable without magnetic validation, rendering the imprinted map incoherent; therefore displacement increases, rather than animals effectively switching to secondary navigation methods under these conditions.
