Poorly marked Clearflight Pieds can look rather like Recessive Pieds, but they may be distinguished from them by the white iris ring, which is always present in adult Clearflights.
Dark-eyed Clears are a combination of the Recessive Pied and Clearflight Pied mutations, having two Recessive Pied alleles and either one or two Clearflight Pied alleles.
