Hunting occurs while flying through the air. They build their nests on cliffs or rock outcroppings. Offspring depend upon parent feeding after hatching. The color of their feathers lacks environmental camouflage.
I gave my students this multiple choice question: Golden eagles can see small objects from great distances. Which behavior of golden eagles best explains why natural selection most likely favored this structural adaptation?

Only one answer is correct among these 4 choices:
- Hunting occurs while flying through the air.
- They build their nests on cliffs or rock outcroppings.
- Offspring depend upon parent feeding after hatching.
- The color of their feathers lacks environmental camouflage.

Could you tell me which one is correct?
