The bald eagle's famous scream is borrowed from a red-tailed hawk

the gist

The powerful screech people associate with bald eagles in films and advertising is actually the call of a red-tailed hawk. Bald eagles make much softer, higher-pitched chirping sounds that sound more like gulls. Filmmakers and sound designers have used the hawk's cry for decades because it sounds more dramatic and fierce. The mismatch persists because the hawk's call fits the image of a raptor better than the real eagle's voice.

so what

The swap shows how pop culture can shape people's beliefs about wildlife, which affects how they recognise birds in the field. Knowing the real call helps birdwatchers identify species by sound.
