The Thunderbird is a powerful bird-like spirit found in the traditions of many Indigenous peoples of North America, from the Pacific Northwest Coast to the Great Lakes, the Plains, the Southwest and the Northeast. In these traditions, it is a supernatural being that creates thunder with its wings and lightning with its eyes, fights the powers of the underworld and waters, and protects or punishes people. Separately, “thunderbird” has also become a label in cryptozoology for reports of giant birds over North America, such as the 1977 Lawndale, Illinois, incident and the famous “lost” Thunderbird photograph. This entry covers both, while keeping them clearly distinct: Indigenous traditions describe a spirit, not an undiscovered animal.[1][2]

A spirit of the upper world
Thunderbird traditions differ from nation to nation, and it is a simplification to speak of “the” Thunderbird as one being. Across many cultures, thunderbirds are imagined as great birds of prey, or as beings combining human and bird forms. In Algonquian tellings, the beating of their wings makes thunder, and in both Algonquian and Iroquois tellings, lightning flashes from their eyes. They are often protectors who may intervene on people’s behalf, but expect respect, prayer and offerings in return. Archaeological sites with images of thunderbirds go back roughly 4,000 years; petroglyphs near Twin Bluffs, Wisconsin, are in a rock shelter used from about 250 BCE to 1500 CE.[1]
Thunderbirds across North America
- Algonquian peoples of the Great Lakes, eastern Canada and the northeastern United States describe a cosmos divided between the thunderbirds of the upper world and the Underwater Panther or Great Horned Serpent of the underworld. The thunderbirds hurl lightning at the creatures below.[1]
- Ojibwe tradition says the thunderbirds were created by Nanabozho to fight the underwater spirits. They live in the four directions, arrive with the other birds in spring and go south in the fall, after the underwater spirits’ most dangerous season, and they punish people who break moral rules.[1]
- Menominee tradition places the thunderbirds on a floating mountain in the far west. They control rain and hail, delight in fighting, and battle the great horned snakes to keep them from overrunning the earth.[1]
- Ho-Chunk tradition says that a man who sees a thunderbird in a vision during a solitary fast will become a war chief.[1]
- Arikara tradition includes a story recorded by the ethnographer George Dorsey of a boy who protects a nest of young thunderbirds from a two-headed serpent that rises from a lake.[1]
- Pacific Northwest Coast peoples tell of struggles between the Thunderbird and the Whale, and the Thunderbird is a major figure in their carving and painting.[1]
The struggle between thunderbirds and underwater beings links this entry to the Piasa of Illinois, whose original painting probably depicted the Underwater Panther, the Thunderbird’s great opponent.[1]
Thunderbird, Whale and the 1700 earthquake
One of the most remarkable findings about Thunderbird stories comes from seismology. In 2005, the University of Washington researcher Ruth Ludwin and colleagues published studies in Seismological Research Letters arguing that Native oral traditions of the Northwest Coast preserve memories of real earthquakes, tsunamis and landslides. They identified stories from northern California to Vancouver Island that likely describe the great magnitude 9 Cascadia subduction zone earthquake and tsunami of January 1700. In some of these stories, the Thunderbird seizes the Whale, its talons sinking into the Whale’s back, in imagery that evokes violent ground shaking and the surge of the sea.[3]
Thunderbird nests
Across Manitoba, Ontario and neighboring regions, circular features in the landscape are known in English as “thunderbird nests,” a name that passed from Indigenous languages into archaeology. Some are rings of boulders: one excavated by the archaeologist Patrick Carmichael at Lake Wanipigow, Manitoba, was about 6.5 meters across and made of hundreds of boulders weighing 20 to 50 kilograms each. A local elder told him the Thunderbird had built it, asking what man had the power to lift such stones. Others are large depressions in boulder fields. Their original purpose remains uncertain.[1]
Could the Thunderbird be based on real animals?
Indigenous traditions describe the Thunderbird as a spirit, but some writers have suggested natural inspirations for the stories. The folklorist and historian of science Adrienne Mayor has suggested that discoveries of pterosaur fossils may have helped shape some thunderbird traditions, and the anthropologist Paulette Steeves has proposed that they preserve memories of the extinct giant bird of prey Teratornis. These are hypotheses, not established facts, and many Indigenous people regard the Thunderbird as a living spiritual reality rather than a memory of fossils or animals.[1]
The Thunderbird as a cryptid
Since the twentieth century, cryptozoologists have used “thunderbird” for reports of giant, unknown birds across North America, ranging from condor-like birds to pterosaur-like creatures. These reports have no direct connection to the Indigenous traditions beyond the name.[1][2]
The Tombstone story and the lost photograph
On 26 April 1890, the Tombstone Epitaph in Arizona published a story about two ranchers who chased and shot a gigantic winged monster in the desert, a smooth-skinned, featherless creature with bat-like wings and a head like an alligator’s, of absurdly huge dimensions. The story was almost certainly one of the tall tales common in frontier newspapers, and it mentioned no photograph.[2][4]
The idea of a photograph came much later. In 1963, the writer Jack Pearl claimed in Saga magazine that the ranchers had photographed the bird nailed to a barn wall with men standing beneath it. The naturalist Ivan T. Sanderson said he had once had a copy, and many people remember seeing such a photo in a book or magazine, yet none has ever been found. Several images circulated as “the Thunderbird photo” have been exposed as modern fakes. The case is often cited as an example of a false shared memory.[4]
Lawndale, Illinois, 1977
The best-known modern encounter took place on 25 July 1977 in Lawndale, Illinois, when several boys said they were attacked by giant birds, described as all black with a white ring around the neck. According to the cryptozoologist Loren Coleman, a boy named Marlon Lowe was briefly lifted off the ground in a bird’s talons. Coleman and his brother interviewed witnesses and families. Earlier Illinois reports came from Overland and Alton in 1948, and a series of sightings was reported in rural Pennsylvania in 2001.[2]
Explaining the giant birds
Witnesses’ size estimates of birds in flight are notoriously unreliable, especially with no nearby object for scale. Large known birds, such as vultures, eagles and condors, which have wingspans of nearly 10 feet, can explain many reports; some of the 2001 Pennsylvania sightings have been attributed to condors. The white neck ring described at Lawndale resembles the white ruff of an Andean condor, though no known North American bird could carry off a child. No body, bone or clear photograph of a giant North American bird has ever been produced, and the scientific community dismisses the reports as misidentifications of known animals.[1][2]
Other winged cryptids in this index include the Snallygaster, the Jersey Devil, the Ropen and the Kongamato.
The Thunderbird in modern culture
The Thunderbird’s name and image are everywhere in modern North American life, from the U.S. Air Force’s Thunderbirds demonstration team and the Ford Thunderbird to sports teams, the Canadian Forces Military Police badge and the 1960s TV series Thunderbirds. Some uses, particularly school team names and mascots, have been challenged, including in a 2023 lawsuit involving a Long Island school district.[1]
Our assessment
The Thunderbird is first and foremost a sacred figure in many Indigenous traditions, a spirit of storm and sky, not an animal awaiting discovery, and it deserves to be understood on those terms. The modern cryptozoological “thunderbird” is a separate phenomenon, built on tall tales such as the 1890 Tombstone story, a photograph that probably never existed, and sincere but unverifiable sightings of very large birds. Known birds and the difficulty of judging size in the sky explain those reports far better than surviving teratorns or pterosaurs.
