This fascinating clip, which was uploaded to YouTube on October 3rd, was recorded by user ‘Stargell Blackstar’ who had been out hunting with his wife and young grandson.

They were approximately 45km from Sioux Lookout in Ontario, Canada when they started to hear a series of loud, mournful screams coming from somewhere nearby.

The chilling vocalizations continued for several minutes, leaving the couple very disconcerted. The video, which has racked up almost 45,000 views at the time of writing, has attracted quite a few comments from other users who have been speculating over what the creature might be.

“I looked up bear roars/howls here on YT, they do NOT sound like this,” wrote user Jenn J. “This sounds like a monster. Notice it stopped when your little one yelled back ?”

“Yes we noticed it stopped for a bit when my boy shouted back,” the uploader replied. “He started to get scared at the end of the video.”

You can listen to the recording for yourself below – the volume is low so headphones are advised.

One thing’s for sure – this is not something you’d want to hear while walking alone in the woods…
