What areThungerbirds? Let's talk about them.

High above the horizon of myth and memory, where storm clouds gather and folklore takes flight, there exists a creature spoken of in whispers and witnessed in flashes of shadow against thunderheads. Long before the term “cryptid” entered the modern lexicon, Indigenous nations across North America told stories of colossal birds whose wings summoned thunder, whose eyes flashed with lightning, and whose presence shaped the balance between sky, earth, and spirit.

But these legends don’t remain confined to ancient tradition. Scattered throughout the 19th and early 20th centuries are unsettling reports from settlers, soldiers, and townsfolk—accounts of enormous birds blotting out the sun, carrying off livestock, and leaving witnesses frozen in awe and terror. Photographs rumored to exist, newspaper clippings half-forgotten, and eyewitness testimony too consistent to easily dismiss all blur the line between sacred symbol and biological anomaly.

Are these mysterious avians purely mythic guardians of the sky, misunderstood metaphors etched into cultural memory? Or could they represent a surviving relic of the prehistoric past—an undiscovered giant raptor soaring just beyond the edges of accepted science?
