Since the Vulture is featured here, the related and simpler pieces Biok and Roshop (V. R. Parton, Chess Curiouser & Curiouser, 1961) should be added here. Alternatively, the Vulture can be postponed to a part where Biok and Roshop are featured.
Biok moves as Bishop, captures as Rook. Appears in "Enlarged and Improved Chess" (1969) as Ensign (original German: Fähnrich).
Roshop moves as Rook, captures as Bishop. Appears in "Enlarged and Improved Chess" (1969) as Guard (original German: Trabant)
