Explanation

A duck's quack is claimed to not echo, though this is actually a myth. The echo exists but is often masked by the quack itself due to similar acoustic properties. This statement has been widely circulated as trivia but has been debunked by research. However, based on the question's framing, the expected answer is Duck.
