Feather duster budgie

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. This condition is sometimes known as chrysanthemum feathering. The contour, tail and flight feathers do not stop growing, and they do not have the necessary barbs and barbules for the feather's structure to interlock. The shaft (calamus) is also curved, and so the feathers appear deformed and fluffed out. Individuals with this condition often appear less alert than nest mates. In addition, they are small and some have other defects such as microphthalmia. Feather duster can not fly too high but take small flights. It is usually stated about them that they die within a year of hatching but that's not true. They reproduce efficiently and they don't have any genetic disorders.
