← Nature & AnimalsWhich risk increases when a soaring bird experiences strong thermal updraft shear?
A)Feather separation reducing lift
B)Increased metabolic energy consumption
C)Disorientation inducing flight stall✓
D)Dehydration from excessive panting
💡 Explanation
When a soaring bird encounters strong thermal shear, abrupt changes in lift occur because airflow separates from parts of the wing, leading to disorientation and a potentially uncoordinated stall. Therefore disorientation results, rather than feather separation, increased metabolic demand, or dehydration, which require either wing damage, strenuous musculature, or overheating.
