Cockatrice

Cockatrice. This creature, which, of course, is entirely imaginary, is depicted in heraldry as having the beak, head, comb, wattles, and legs of any ordinary cock, and the body, the wings, and the tail of a wyvern, i.e. its body is elongated and curled round, gradually diminishing in breadth until it ends in the barbed tail of the dragon. The wings are exactly as those of this latter animal, and are always shown to be elevated, whilst occasionally they are also expanded one on each side.
