What is rarest budgie?

The rarest budgie is the English White Budgie (Albino), which is a pure white bird with pink eyes. This variety of budgie is not easily available and is considered extremely rare due to a recessive gene that causes the lack of pigment in the feathers, beak, and eyes. The English White Budgie is very popular among breeders and pet owners due to its unique and stunning appearance. However, due to the difficulty in breeding and rarity, they can be expensive to purchase. Other rare budgies include the Yellow-Faced Parblue, Texas Clearbody, and the Double Factor Spangle.
