Show, English, and Normal Budgies Size Differences +PHOTOS

Normal budgies and English budgie species are different-sized budgies that are caused by selective breeding.

Why English and Show Budgies Are Bigger Than Wild, American, and Normal Budgies?

English budgerigars were bred from wild budgerigars using the selective breeding method in the early 1800s. During selective breeding, large budgerigars were selected repeatedly in each generation. Over time, the budgerigar population in England has diverged from wild budgies in size and emerged as a new subspecies of budgies.

In the same way, show budgies are generally continued to be produced from English budgies. That’s why English and show budgies are larger than wild, normal, and American budgies.

On the other hand, wild budgies still live on the Australian continent today. Wild budgies are still taken from the wild to be taken to other parts of the world and reproduced there. Therefore, budgies other than English show budgies are typically close to wild budgies in size.

What Age Are Budgies Fully Grown?

It takes 40-45 days for a budgie chick (baby) to visually look like an adult.

A budgie baby is fully grown at 40-45 days old. After 40-45 days, the budgie chick visually looks like an adult.

Although baby budgies stop visually growing after 40-45 days, their hormone and reproductive systems continue to develop.

Why Are Male Budgies Bigger Than Females?

Male budgies have slightly more muscle mass than female budgies. This is the main reason why, among male and female budgies of the same age, the male ones are slightly larger than the females.

In many cases, as many budgie owners report, male budgies are slightly larger than female budgies. However, this difference cannot be understood by an amateur eye. In addition, male and female budgies must be the same age when it comes to size comparison.

Do Show and English Budgies Need Bigger Cages?

Yes, show (exhibition) and English budgies need bigger cages than normal and American budgies. This is because English and show budgies have bigger sizes and longer wingspans.

English budgies have a wingspan of approximately 16 inches (ca. 41 cm). According to rspca.org.au, a budgie cage size should be a minimum of three times their combined wing spans for a pair of budgies.

Are English Budgies Bigger Than American Budgies?

Yes, English budgies are bigger than American budgies. English budgies are nearly twice the size of American budgies and wild budgies and are a subspecies of budgerigars that emerged by selective breeding since the early 1980s. On the other hand, American budgies are the bird population that is the size of wild budgies and is found within the borders of America.
