The bald eagle has long been a symbol of the United States, and its sharp cry has become audio shorthand for wilderness and freedom in film, television and online video. Although the sound is instantly recognisable, it is often used more for its dramatic effect than for strict realism, placed over soaring landscapes, patriotic montages and nature clips. On soundboards and in memes, creators reuse the short clip because it is immediately understood, needs no explanation and instantly sets a grand, outdoors tone.
