How does it tell the difference between a crow it has seen before and a new crow? Would it just dispense free peanuts to all crows?

  It dispenses in response to cigarettes, not crows (at least after training), so it wouldn't really matter I don't think.

    > (at least after training) That is the question. The article described "training" as progressing from free peanuts to peanuts for butts.

      Maybe after the initial training period they just rely on crows learning from each other
