Not long ago, I was watching "Game of Thrones," the megahit HBO show set in the fictional world of Westeros, when I heard a sound I knew well: the long, high call of the common loon. I'd heard it a thousand times, on a hundred lakes, and here it was in a scene overlooking the peaceful (but soon to be blood-soaked) castle of Riverrun. The bird was clearly meant to signal a place far away in the wild.
The loon call is a common sound effect. But for me, hearing the loon in the middle of a show is jarring, because it's so distinct and my own memories of it are so clear. No doubt this is a common experience for any northerner watching any film set anywhere in the wilderness: In a moment of quiet repose, a loon will be there. But rather than immersing us more deeply in the film, it pulls us out.
"Loon is definitely a popular sound," said Greg Budney, who was the audio curator at the Cornell Lab of Ornithology in Ithaca, N.Y., for nearly 40 years. "It seems like after 'On Golden Pond,' [the loon's] use as a sound effect increased. It appears in all kinds of films, from the African desert to the southwestern U.S."
The Cornell Lab is where Hollywood goes shopping for bird sounds. Sound designers would call Budney and his colleagues to ask for a call. Sometimes they knew what they wanted. Other times they didn't.
"They're trying to elicit a particular emotional response from the audience," Budney said. "And the loon's wail, which is a contact behavior, has a mournful quality, and that's often what they're going for."
The loon has four different calls. The wail is most popular in films. Next is the tremolo, what wilderness advocate and writer Sigurd Olson called, "wild, rollicking laughter." Then there are also the lesser known (and lesser used) yodel and hoot. It was the tremolo that Katharine Hepburn loved (and badly mimicked) in "On Golden Pond."
Since then, the loon has had cameos in everything from the savanna in "Out of Africa," to the Canadian winter in "The Revenant," to the prehistoric "Quest for Fire." Whenever a producer wants to say you're far from civilization (or help), in goes the wail. It appeared more recently at the end of "Avengers: Infinity War," when the villain Thanos sits down to mourn all he's lost. The sun sets. The loon calls.
The allure
It's no wonder Hollywood loves the loon: There is no sound quite like it on earth. When you are alone at night on a northern lake, the wail goes right though you. It's a sound you feel with your whole body. Echoing across the water, it feels ancient and lonely, like something rising from the distant past. And in a sense it is: Loons are one of the oldest living birds, with fossils dating back as far as 70 million years. It's easy to imagine that their call is as old as their bones.
