In the beginning of the 20th century, the keeping and breeding of budgerigars became very popular all around the world. Consequently, various colours and mutations occurred during this period.

This is dedicated to all people who like blue budgies: the first sky blue budgerigar was recorded in 1878 in Belgium (suddenly I like my home country a little bit more!). Sadly, this mutation disappeared only a few years later, because very little was known about budgies back then, and no one understood how the colours were created.
