Why do some diurnal birds sing at night? Roman, Columbus, Georgia. A primary reason male birds sing is to attract mates, and it has been found that unmated mockingbirds and nightingales sing at night more frequently than mated males.

Until relatively recently, not too many other species of diurnal songbirds were known to regularly sing at night. In the last decade or so, researchers have determined that more bird species are singing at night in urban areas so that they do not have to compete with ambient noise such as traffic sounds that are more common in the daytime. In addition, some species have started singing earlier in the day or have increased the volume of their songs in noisy places.

Not only is human-created environmental noise often simply loud, but it tends to be generated at lower acoustic frequencies. A number of species, including Song Sparrow and House Finch, have been found to sing with modified acoustic frequency in response to human-generated lower-frequency noise, reducing the masking of their lower-frequency notes by ambient clamor.
