The Thunderbird
The Thunderbird of Native American legend appears to be more than myth. Giant birds with wingspans exceeding 6 meters have been reported across North America, and in 1977, a boy was allegedly grabbed and lifted by an enormous bird.

The Day a Myth Took Flight
July 25, 1977. Lawndale, Illinois. Ten-year-old Marlon Lowe was playing in his backyard.
Two massive birds appeared overhead without warning. One dove straight at the boy and seized his shoulders in its talons. Marlon was lifted roughly two feet off the ground. His mother, Ruth, ran screaming toward him. The bird released the boy and soared away.
Marlon had been carried approximately 10 meters. His mother and two neighbors witnessed the entire event. The bird's wingspan was estimated at over three meters. It was black, with a distinctive white ring around its neck.
No bird in North America is large enough to lift a child. At least, not officially.
The Bringer of Thunder
The Thunderbird is one of the most universal figures in Native American culture. From the Kwakiutl of the Pacific Northwest to the Lakota of the Great Plains, tribes across the entire continent share legends of an enormous bird.
As its name suggests, the Thunderbird was a supernatural being that commanded storms. The beat of its wings produced thunder. Lightning flashed from its eyes. For many tribes, it was an object of both terror and reverence.
But here is what makes the Thunderbird legend unusual: in many indigenous traditions, the creature is described not as a purely mythological entity but as a real, physical bird that people occasionally encountered.
A History of Sightings
Modern sighting reports began proliferating in the late 19th century.
In 1890, a newspaper in Tombstone, Arizona reportedly published a story about cowboys who killed a flying creature with an 11-meter wingspan in the desert. The article allegedly included a photograph. That photograph has never been located. The "missing Thunderbird photo" has become one of the most enduring mysteries in cryptozoology—countless people claim to remember seeing it, yet no one can produce it.
In 1948, multiple residents of Illinois reported a bird with a wingspan exceeding six meters. In 2002, a giant bird was spotted flying alongside a small aircraft in Alaska. The pilot estimated its wingspan at roughly 4.3 meters.
What Science Says
The largest flying bird in North America today is the California Condor, with a maximum wingspan of approximately 2.9 meters. Thunderbird sightings consistently describe something far larger.
Intriguingly, such birds did once exist on this continent. The Pleistocene-era Teratornis merriami had a wingspan of about 3.5 meters, while the even larger Argentavis magnificens exceeded seven meters. Both are believed to have gone extinct roughly 10,000 years ago.
But 10,000 years is a geological blink. And North America still contains vast stretches of wilderness where a small, reclusive population could conceivably survive undetected.
Look up. That shadow passing overhead—are you certain it is just an airplane?
