Which behavior occurs when a cave swiftlet's **signal masking** limit is exceeded?

💡 Explanation

Reduced swiftlet density foraging occurs because exceeding the signal masking limit impairs ability to distinguish individual echoes. Accuracy drops; therefore foraging plunges--rather than improving predator detection or swiftlet metabolism whose influence is independent of location acoustics.
