A vending machine for crows

Or, perhaps more accurately, "a self-contained training machine for crows, causing them to learn that dropping coins into a funnel will provide them with peanuts for food." 
Or, more succinctly, "training crows to steal change, for fun and profit."

I'm not sure what I want more;  the franchise for a chain of these around e.g. Central Park or the Tivoli Fountains, or one that rents giant transparent crow-deflecting umbrellas to sell to pedestrians passing through those areas.
