Flocking tall.

Bird watchers are blowing the internet’s collective mind after sharing a video of a “mutant pigeon” with a puffed out breast and legs so long viewers suspected it was an AI deepfake.

A now-viral video of the stretchy squab has amassed over 18.6 million views on TikTok as viewers debate if the animal is real.

The seemingly species-defying clip — shared by UK-based @pigeonsTV — features the awkward-looking rock dove strolling along a table with its mile-long legs while its bulbous breast at full mast.

Its towering, top-heavy countenance evokes thoughts of a regular pigeon — following an Ozempic regimen gone bizarrely wrong.

The gangly bird’s comparably scrawny legs and feet meanwhile are covered in plumes like natural, feather-hemmed pants.

However, as it turns out the bird is actually an English pouter pigeon, a species of homing pigeon that’s the “tallest breed of fancy pigeons with some of the biggest ones being 16 inches in height,” according to Backyard Poultry.

The flamboyant featherbag is known for being able to inflate its crop — the muscular pouch on the inside of its neck.

Bred through centuries of selective breeding, the fancypants pouter is often referred to as the “supermodel” of the pigeon world due to its resplendent appearance — think of it like bird equivalent of a French poodle.

Needless to say, the pigeon’s “Dr. Seuss”-esque visage raised many eyebrows on social media.

“Stage 3 pigeon Pokémon, bro evolved,” quipped one gawker, while others compared it something celebrities would wear at the “Met Gala.”

“That’s definitely two pigeons under a trench coat,” said another.

“Me drawing a pigeon from memory,” one TikTok wit joked.

Another wrote, “What in the A.I generated pigeon is that?”

Some even thought the bird was a regular pigeon that got plucked a la those countless videos of dogs with botched haircuts.

Although, in the realm of ornithological oddities the Pouter has nothing on the blue-plumed Victorian crowned pigeon — the world’s largest species named for its extravagant, burlesque-looking headdress.

Or how about the Nicobar pigeon, which boasts a multihued mane of dreadlocks worthy of a hackey sack salesman.

Meanwhile, this “mutant pigeon” isn’t he first fowl creature to snag headlines this year: A feisty pigeon hilariously interrupted a Floriday meteorologist’s weather report in May, and a pair of Canadian pigeons were busted sporting “drug smuggling” backpacks in January and March, respectively.
