Ranging from metallic hisses to electronic yodels, sounds of grackles may not be music to our ears—but they have their own rough beauty, a distinctive, primal harshness. Grackle songs evolved to carry through their nesting habitats — dense marshes and brushy landscapes — where more lyrical notes and phrases wouldn’t carry well. However strange they may sound, they know how to make themselves heard.

The sounds of grackles may not be music to our ears—but they sure do get your attention. And they have their own rough beauty, a distinctive, primal harshness.

Male grackles sing to attract mates and ward off rivals. However strange to our ear, their songs work well.
Grackles are oversized blackbirds. Of three grackle species in North America, the Common Grackle of the eastern states has the simplest song, with metallic hisses and raspy quavers:

And a mob of foot-long males in the same tree make an otherworldly racket:

The 16-inch Great-tailed Grackle of the Southwest sings the most complex grackle song, a symphony of squeaky hinges, explosions of static, and electronic yodels.

So… why do they sound so harsh and jangly? Grackle songs evolved to carry through their nesting habitats — dense marshes and brushy landscapes — where more lyrical notes and phrases wouldn’t carry well.

Grackles may not be the most... melodious singers, but they sure know how to make themselves heard.
