On this occasion, which took place in 2016, cameras at the station had picked up a passing Canada lynx. Coming to a stand-still right in front of the device, the big cat let out an unusual call. According to the video’s description, this was a rare example of a lynx vocalization.
The strange noise sounded more like a bark than anything normally associated with a cat – big or small. Some people refer to the sound as a scream or a yowl. Moreover, those few lucky enough to have heard the vocalization in person have called it nerve-wracking and spine-tingling.
