Quinion does write about it, but not with a lot of detail about its origins, though he goes into great detail about it not coming from an 1888 claim that it came from the War of 1812. This claim was that an American went hunting and accidentally crossed the British lines, where he shot a crow. A British officer caught him and complimented him on his "fine shooting" and persuaded the American to hand over his gun. The officer then levelled his gun and told the soldier that as a punishment he must take a bite of the crow. The American obeyed, got his gun back, and then made the British officer eat the rest of the crow! However, this apparently is not the origin of the word. The first recording of "eat crow" occurred in the 1850s and referred to eating a boiled crow.
Beyond that fun story, Quinion just seems to guess at the origins with this statement: " The origin seems fairly obvious: the meat of the crow, being a carnivore, is presumably rank and extremely distasteful, and the experience is easily equated to the mental anguish of being forced to admit one’s fallibility."
The concept may go back much farther. According to Online Etymology, the name "Walter Etecroue turns up 1361 in the Calendar of Letter Books of the City of London."
Quinion says, "The origin seems fairly obvious: the meat of the crow, being a carnivore, is presumably rank and extremely distasteful, and the experience is easily equated to the mental anguish of being forced to admit one’s fallibility."
Oh, really? No offense, Mr. Quinion, but consider:
For one thing, the crow is not a carnivore; it is an omnivore.
For another, where does he get the notion that carnivore meat is necessarily "rank and extremely distasteful"?
Finally, even if crow meat is unusually distasteful, it's quite a leap from there to the idiom. Do you know whether enough people had sampled crow to make its putative bad taste well enough known to be proverbial? And why, of all distasteful experiences, was this particular one selected for metaphor, with no visible connection between this particular "distaste" (of crow) and the "distaste of admitting fallibility"?
It seems to me that Quinion has not thought the matter through with his usual thoroughness.
When I read it, I thought that there are a lot of things that I can think of that might taste "rank and extremely distasteful." I wondered why the "crow" was specifically identified for this meaning.
You know, Kalleh, that's a great question! In thinking about it myself, I'd think that it's because the crow represents (for me) a loud, obnoxious-sounding bird. The crow's caws are noisy rather than lyrical, and harder to feel comfortable with. I wonder if that is why crow is the bird of choice when needing to admit to having said or done something one shouldn't have.

I understand what it means, but I just don't get why "crow" was chosen; there are many other beasts that would be "rank and distasteful," I am sure...for instance, a rat!
