A video from Japan showing a crow resembling a gorilla on all fours has puzzled millions on Twitter over the last few days.

The animal, which has since been dubbed a “gorilla crow,” was filmed at the Parco shopping center in Nagoya, Aichi Prefecture last week.

The video, which user @keita_simpson shared on June 20, has since received nearly 10 million views, 250,000 likes and 115,000 comments.

Speaking to Newsweek, @keita_simpson said that he was initially shocked at the sight of the creature, since it looked like a “zombie.”

However, after observing the animal for a minute, he then thought it was actually pretty.

“Thank you for giving me a shock this morning,” @keita_simpson wrote in his post. “Bad for the heart.”

As the video made rounds on the internet, Dr. Kaeli Swift, a researcher of corvids — the family of birds including crows — from the University of Washington, shed some light on the creature’s behavior.

According to Swift, the bird is a large-billed crow, which explains why its face is “a little out of proportion.”

There’s a very strange (uncredited) video of crow making the rounds on reddit. Here’s the deal. First, this is a large-billed crow, which is why the face is looking a little out of proportion. pic.twitter.com/LUYuMimvAp — Kaeli Swift, PhD (@corvidresearch) June 22, 2019

“This bird is not missing its legs and propping itself up with its wings, that would be physically impossible,” Swift continued. “Also, not that it’s relevant to the answer, but a crow without legs couldn’t fly, because it couldn’t generate any lift.”

She added, “Legless crow is a dead crow.”

Second, this bird is not missing its legs and propping itself up with its wings, that would be physically impossible. Also, not that it’s relevant to the answer, but a crow without legs couldn’t fly, because it couldn’t generate any lift. So legless crow is a dead crow. — Kaeli Swift, PhD (@corvidresearch) June 22, 2019

Swift explained that the bird exhibited a common behavior called “sunning,” which is typically done as a feather care measure.

“When birds sun they drop their wings and cock their tails. At the right angle that could obscure the legs and tail making it look like they’re missing.”

What it’s actually doing is sunning itself. When birds sun they drop their wings and cock their tails. At the right angle that could obscure the legs and tail making it look like they’re missing. — Kaeli Swift, PhD (@corvidresearch) June 22, 2019

Usually the mouth is open and the body is closer to the ground, making the behavior more obvious, but perhaps the videographer caught it in a moment of transition. — Kaeli Swift, PhD (@corvidresearch) June 22, 2019

In any case sunning like this is a common behavior among birds. Sometimes it’s about warming up but a lot of times you’ll see them do it when it’s hot out. In these cases it’s about feather care. Sun exposure can reduce feather degrading bacteria and mites. — Kaeli Swift, PhD (@corvidresearch) June 22, 2019

Swift also told Newsweek that the crow in the video may actually be a starving adult.

“If you look at the bird’s chest you can see it’s more V shaped than round, that indicates that it is emaciated. Since malnourished or sick birds will droop their wings like that, that could explain the behavior entirely, especially because its mouth isn’t open or its head cocked to one side, which are part of the typical sunning posture as I indicated in my drawings.”

While Swift has already shared eye-opening information on the video, some have accepted co-existing with “gorilla crows.”

look Kaeli you don’t have to lie to us about the existence of the gorilla crow — Adam Fleischmann (@afleisch_anthro) June 22, 2019

this all is not true, obviously, we are looking at a bird that has evolved! — San Holo 🦜 (83%) (@sanholobeats) June 23, 2019

Meanwhile, others created artworks to both joke about and make sense of the sight.

I draw the picture. Because your video is so funny. He looks like standing with his four legs.😂😂😂😂😂 pic.twitter.com/PSx206YREO — ✦ ᴅᴀɴɪ ✦ (@Fiorevento) June 22, 2019
