The Celts believed birds to be celestial messengers and bearers of magical power. The raven is the bird of prophecy, the pheasant of good fortune and the **partridge ** is a symbol of cunning and also of Christ; hence the “partridge in a pear tree”.
The partridge has two opposing meanings. It may be used as a symbol of the church and truth, or as a symbol of deceit and theft. Most commonly, however, the partridge is considered a symbol of the devil.
The “Doll Partridge” referred to by your frinds was a slang term applied to a harlot who played the young innocent. It described the dual nature of the role, and the affected sweet “doll” quality she would use.
Not really…I just made that bit up. I have no clue what they are talking about either.
