A domestic half-sider budgerigar. A half-sider budgerigar is an unusual congenital condition that causes a budgerigar to display one color on one side of its body and a different color on the other. This is not a simple genetic mutation, as can be observed in other color and pattern variations in this species.

The wildtype (natural-coloured or wild occurring) budgerigar's color is called Lightgreen. The feathers of most parrot species, including budgerigars, contain both a black type of melanin named eumelanin along with a basic yellow pigment named psittacofulvin (psittacin for short). Some other parrot species produces a third pigment named ...

Loriinae is a subfamily of psittacine birds, one of the six subfamilies that make up the family Psittaculidae.It consists of three tribes, the lories and lorikeets (), the budgerigar (Melopsittacini) and the fig parrots (Cyclopsittini), which are small birds, mostly of bright colors and inhabitants of Oceania and the islands of Southeast Asia.
The Recessive Pied budgerigar mutation is one of approximately 30 mutations affecting the colour of budgerigars. It is the underlying mutation of the Danish Pied variety, aka Harlequin. It is believed by Inte Onsman of MUTAVI [1] to be the same mutation as the Anti-dimorphic Pied (ADM Pied) found in some parrots. [2]
The Clearflight Pied budgerigar mutation is one of approximately 30 mutations affecting the colour of budgerigars. It is the underlying mutation of the Continental Clearflight and Dutch Pied varieties. The Dark-eyed Clear variety results when the Recessive Pied and Clearflight Pied characters are combined.

The loci of the Dark budgerigar mutation and the Blue allelic series are situated on the same autosome, so the Dark mutation is linked to the Blue allelic series (see genetic linkage). The cross-over value (COV) or recombination frequency between the Dark and Blue loci is commonly stated to be about 14%, [ 6 ] but some experiments have found ...
