“Pigeons explode if they eat uncooked rice.”

The notion that birds, specifically pigeons, will explode if they consume uncooked rice is a persistent urban legend, often linked to the tradition of throwing rice at weddings. This misconception gained significant traction in the late 1980s and 1990s, largely fueled by widely circulated letters and advice columns that warned of the supposed danger. People were led to believe that dry rice would absorb moisture in a bird's stomach, expand dramatically, and cause fatal internal ruptures.

However, scientific evidence and ornithological research unequivocally debunk this claim. Birds possess highly efficient digestive systems, including a muscular organ called a gizzard, which grinds down tough foods like seeds and grains, often with the aid of small stones. While uncooked rice does absorb water and swell, a bird's internal body temperature (around 37-40°C) is not high enough to "cook" the rice to the extent that it would rapidly expand and cause harm. Furthermore, birds have a rapid metabolism, meaning food passes through their digestive tracts relatively quickly, often within minutes or a few hours, not allowing sufficient time for dangerous expansion. Studies by organizations like the National Audubon Society and Cornell Lab of Ornithology confirm that birds safely metabolize uncooked rice, and many wild species, including pigeons, ducks, and geese, routinely consume rice as part of their natural diet in agricultural areas without any ill effects.

The myth's enduring popularity likely stems from its dramatic imagery and the plausible, though incorrect, assumption that what happens to rice in boiling water would occur inside a bird. The well-intentioned desire to protect wildlife, combined with the power of misinformation spread through anecdotes and early media reports, allowed this false narrative to become deeply ingrained in public consciousness, despite a complete lack of scientific support.
