← Nature & AnimalsWhich outcome results when seasonal food abundance influences migratory bird destination selection?
A)Habitat-linked navigation accuracy increases rapidly✓
B)Genetic drift overwhelms initial map cues
C)Olfactory map fidelity progressively diminishes
D)Mortality risk in novel areas decreases
💡 Explanation
Improved navigational success occurs because destination choices adapt to fluctuating food based on habitat linked navigational signals, specifically the **olfactory map**. Birds refine destinations using smell; therefore habitat-linked accuracy rises rather than diminishes without direct links.
