Passage Summary: These birds have a habit of barking loudly to warn their group about predators, but this actually makes it easier for the predators to find them when they would have been safer just staying hidden and quiet.

Reasoning: The stimulus provides facts about babblers: they bark to warn others of predators, yet they are well-camouflaged and would be safer staying quiet, as the barking actually helps predators find them.

Analysis: This is a paradox question centered on an evolutionary mystery: why would a species continue a behavior that seems to decrease its chances of survival? The barking is intended to protect the group, yet it serves as a homing beacon for the very predators they are trying to avoid. To resolve this, look for an answer that provides a hidden benefit to this behavior that outweighs the risk of being spotted. Perhaps the barking serves a different protective function or benefits the group in a way that isn't immediately obvious from the predator's perspective.
