All pied budgerigars are characterised by having irregular patches of completely clear feathers appearing anywhere in the body, head or wings.
They differ from the Clearflight Pied in the nape spot, which is not always present, and in their feet, which are usually pink.
When mated to an unrelated hen in 1933 this cock produced 14 young over three nests, of which 5 showed some clear feathers on the nape of the neck.
Several similar pied birds were reported around the same time in Germany, bred by Herr Krabbe and separately by Herr Schucke,[1][3] by Madame Lecallier in France,[1] by G Wilson and T L S Dooley in England,[1] in Holland[1] and in Scotland,[1] but detailed descriptions and the mode of inheritance are unknown.
The present-day Australian Pieds, including the Banded Pied variety, are believed to be descended from a strain first established in Sydney in 1935[1][4] by Keith Ings.
The extent and distribution of the clear areas shown by both single-factor (SF) and double-factor (DF) Australian Pieds are variable.
The range of variability of the two genotypes appears to be identical, so it is not possible to determine the genetic make-up by considering the extent of the clear areas.
