Now that Nosferatu has been released on digital platforms, viewers have been pouring over every minute of Robert Eggers' atmospheric horror. And it seems that one fan has spotted a very niche mistake on their latest rewatch.

"I swear in Nosferatu there's a North American bird call in the background at some point and I felt like a huge geek for noticing," one fan called Yuribeast tweeted before they shared a clip from the movie where Ellen Hutter is mourning the disappearance of her husband. "I KNEW I WASNT TRIPPING. common loon call at 49:47. Robert Eggers you're under arrest," they added.

For those of you who aren't bird experts, the common loon is a diving bird usually found in North America. Nosferatu is set in the fictional German town of Wisborg in the winter. Now, the fan did go on to say that, "I've been informed that they can be found in Northern Germany (they're called great northern divers in Europe) but winter is still the wrong season for them to be doing breeding calls so being annoyingly pedantic wins again."

Nosferatu tells the chilling story of Count Orlok's (Bill Skarsgård) obsession with Ellen Hutter (Lily-Rose Depp) that leads him to a small town in Germany where he terrorizes the citizens. This marks the third adaptation of the film, and one fan has put all of the versions together in a fascinating comparison video.
