Step 1 : Introduction to the question "2. Which of the following domestically bred birds, originally from Australia, is the most popular avian pet due to its small size, low cost, ability to mimic human speech and playful nature?"
...1. Quail 2. Canary 3. Budgerigar 4. Finch Budgerigars (Melopsittacus undulatus), commonly called 'budgies' in Australia, are often somewhat mistakenly called 'parakeets' in North America (a term which more accurately refers to any of a number of small parrots with long, flat tails). They are also sometimes called 'Lovebirds' due to their habit of mutual preening. Budgies were originally green and yellow in plumage but have been selectively bred to have the countless colours we know today.
