Birds sing louder and at a higher pitch in urban areas, where there is ambient low-frequency noise. [58] [59] Traffic noise was found to decrease reproductive success in the great tit (Parus major) due to the overlap in acoustic frequency. [60] During the COVID-19 pandemic, reduced traffic noise led to birds in San Francisco singing 30% more ...

[ 2 ] According to a study published in 2019, the white bellbird produces the loudest call ever recorded in a bird, reaching 125 dB(A) (at equivalent 1m ...
The archosaurian shift from larynx to syrinx must have conferred a selective advantage for crown birds, but the causes for this shift remain unknown. [10] To complicate matters, the syrinx falls into an unusual category of functional evolution: arising from ancestors with a larynx-based sound source, the syrinx contains significant functional overlap with the structure it replaced.
