A YouTube video that claims to have captured a herd of Bigfoot roaming through Yellowstone National Park has gone viral.

The video, which was uploaded by YouTube user Mary Greeley in late December, has garnered almost 50,000 views. The recording starts off showing a herd of buffalo near Old Faithful in Yellowstone. However, around the 3:00 mark, at least four upright creatures are seen walking in the background in the upper right section of the video.

Yellowstone National Park Spokesperson Al Nash commented on the video, saying that reported Bigfoot sightings at the park happens from time to time.

"Bigfoot sightings are not frequent, but it happens. People say a lot of crazy things about Yellowstone all the time and Bigfoot is just one of them," he told ABC Fox Montana.

According to the Bigfoot Field Researchers Organizations, there have been 43 reported Bigfoot sightings in Montana since the group was founded in 1995.

Last month, a man identified as Russell Strark uploaded a video on YouTube which he claims is a live recording of the mythical beast strolling through Prospect Park in Brooklyn, New York.

According to Strark, he captured the hairy ape-like creature roaming through the park on Tuesday, Jan. 27, on the day that New York City Mayor Bill de Blasio shut down public parks after the city was hit by Winter Storm Juno, reports Pix 11.

"This is Unbelievable footage that I captured in Brooklyns Prospect Park," wrote Strark on YouTube. "I recently started a live streaming / time lapse channel called Brooklyn Live Video to capture different parts of Brooklyn. I had set up a camera in Prospect Park on a side trail to capture the snow fall, today I went back and collected it and found this footage. It appears to me to be Bigfoot.... Seriously. Looks like it was taken at around 7 am this morning."

However, a leading paranormal expert dismissed the alleged video evidence of a Sasquatch lurking through Prospect Park as a hoax.

"I don't know what the f--k this thing was, but usually if it is too good to be true, it's too good to be true," said Lee Speigel, a writer for the Huffington Post's Weird News, to the Brooklyn Paper.
