Eating crow is a U.S. colloquial idiom, meaning humiliation by admitting wrongness or having been proved wrong after taking a strong position. Eating crow is presumably foul-tasting in the same way that being proved wrong might be emotionally hard to swallow. The exact origin of the idiom is unknown, but it probably began with an American story published around 1850 about a slow-witted New York farmer. Eating crow is of a family of idioms having to do with eating and being proved incorrect, such as to "eat dirt" and to "eat your hat" (or shoe), all probably originating from "to eat one's words", which first appears in print in 1571 in one of John Calvin's tracts, on Psalm 62: “God eateth not his words when he hath once spoken”.
