What different parakeets are there?

Answer 1

Budgies come in many different mutation and sizes. But they are all the same species, Melopsittacus undulatus.

But we separate these budgies into three different groups, The wild budgie (which is much smaller than our domesticated pets), The Australian budgie (which amazingly is sometimes called the American, I have no idea why) and the English or Show budgie.

The most common budgie we keep as pets is the Australian budgie. These are the ones you see in ..pet shops (please do not support pet shops!).

All wild budgies are yellow-based normals. All other mutations have been bred by humans.
