Which outcome occurs when a songbird must sing near heavy road traffic?

💡 Explanation

Songbirds will shift to higher or lower frequencies, using frequency adjustments which avoids intense low-frequency noise; therefore, minimizing acoustic masking and signal loss via communication, rather than other methods to communicate under frequency constraints.
