Budgerigar refers to a specific small parrot that originated in Australia. It derives from the Aboriginal bah-charry-ga, meaning "pretty bird" (believe it or not).
Although it is commonly used to refer to budgies, "parakeet" is a term for any one of a large number of unrelated small to medium sized parrot species, that generally have long tail feathers. The term is descriptive, but does not imply an actual relationship between the different parakeets. In the US, "parakeet" usually refers to Budgerigars, but it is not a precise use of the word.
Yes, they are called budgies.
Budgies are native to Australia
I assume that you might be talking about budgies, if so, their class is called 'Aves'.
budgies and parakeets are the same things so yes
30 grams is an excellent weight for an American parakeet. English Budgies are a larger bird and will weigh more.
No. Budgies cannot eat onions, avocados, rhubarb, chocolate, or dairy products.
There is only one way in English, "parakeet" (some also referred to as budgies).The term comes from the Spanish periquito.
If, by "parakeet", you mean any of the smallish parrots with long tails, such as budgies or cockatiels, then no, it most certainly does not have to be the same colour.
Presuming that 'parakeet' means budgie, even though there is actually no species known as a parakeet, the cere, which is the part above a budgies's beak where their nostrils are, is bright blue on a mature male budgie.
A parakeet would probably like the following: a medium sized ball, a swing, a rope, and a bell. Be careful to not buy a too small toy, as it can be swallowed. These all can be toys and probably can be bought at a local pet store such as Pet Smart or elsewhere. Also keep in mind a second parakeet can keep the parakeet company, or some large toy would work too. Happy shopping! :)
budgies can be different clolours like blue white and yellow
There are dozens of different species of small parrot that are called parakeets. The one most commonly kept as a pet is the budgerigar, also known as a budgie. Wild budgies are usually about 7 inches (18 cm) from beak to the tip of their tailfeathers. Captive budgies vary in size, with English/show type budgies being larger than those found in the pet trade in North America.
