  • This appears to be a pigeon which is not a homing pigeon, but is released with homing pigeons to distract the enemy. Wikipedia says,

    "The term "stool pigeon" was first coined when passenger pigeons were captured, had their eyelids sewn shut, and were tied to stools. The birds sitting on the stools would be used as live decoys so pigeon hunters would have an easier shot at their quarry"

    but the whole stool thing doesn't make any sense.

  • Neither does the fact that gazillions of passenger pigeons were slaughtered for food (and thus went extinct), but that happened too, sad to say.... :-\ Never heard that story though, seanahan.

  • Alright, here is what the article says, clarifying the confusing Wikipedia statement. They would stick a dead pigeon on a stool, which would make other birds less wary, since the birds figure if one bird thinks it's safe, it must be.

    I never imagined this term meant something so archaic.
