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 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 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 ...
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 Dominant Grey budgerigar mutation, often called the Australian Grey or simply Grey, is one of approximately 30 mutations affecting the colour of budgerigars. It is the basis of the Grey-Green and Grey standard varieties.
Learn what blue jays symbolize, their spiritual connection to the Bible, if they represent good or bad luck, and what to do if you see a blue jay.
Feather duster budgerigars (Melopsittacus undulatus), sometimes called budgerigar mops, are budgerigars that have a condition characterised by overly long feathers that do not stop growing at usual periods, giving the bird the appearance of a feather duster.
