← Nature & AnimalsWhich outcome occurs when Indigo Buntings raised indoors are seasonally exposed only to artificial, static light?
A)Inability to build fat reserves
B)Disrupted circadian rhythm tracking
C)Failure to correctly molt plumage
D)Inaccurate nocturnal migration timing✓
💡 Explanation
Disrupted orientation occurs because their celestial navigation relies on the Emlen funnel orientation mechanism for star pattern recognition; therefore they cannot determine migratory direction, rather than regulate seasonal body changes under artificial light, or follow a standard circadian rhythm.
