← Nature & AnimalsWhich outcome occurs when homing pigeons face impaired sense?
A)Increased reliance on celestial navigation
B)Random circling and disorientation occur✓
C)Heightened use olfactory landscape cues
D)Unusual migration behavior toward unfamiliar targets
💡 Explanation
Disorientation occurs because magnetic disruption damages their magnetoception process. Magnetic sense is key for initial direction finding; therefore, randomized circling results, rather than celestial or olfactory maps compensating at short ranges when magnetic information is incorrect.
