Mourning Dove Feathers Make “Wing Whistles”
That’s right—the squeaky noise isn’t the bird chirping! The sound you hear when a mourning dove flies comes from special feathers on its wings. The noise is called “wing whistles,” and it occurs when air rushes through those feathers and causes them to vibrate. Because mourning doves don’t have varying calls, mourning dove wing whistling serves an important purpose. It allows the birds to convey urgency and danger to the rest of their flock.
Wing Whistles Help Other Birds
Scientists have proven that other birds respond to wing whistles. They recorded the sound of crested pigeons—a mourning dove relative—flying normally, as well as fleeing in fright. When they played those recordings for other pigeons, the scientists discovered the birds paid no mind to the “normal” flying-away sounds. But when they heard the alarmed wing whistles, they took off. Other species of birds use the noise as a signal, too.
While wing whistles might sound odd to us humans, they serve an important purpose. When the bird takes off in alarm and mourning dove feathers sing their song, it signals to other birds in the vicinity that danger is near. Those birds then know to head for cover or be on the lookout for predators.
