they are protecting their egg.
About twice as hard as a Budgie.
you can t determinate if your bird is a boy or a girl if he likes to bite your clothes. if a cockatiel is a boy his tail will have patterns on it otherwise if it is a girl she will be plain.
he is probably trying to attract her for mating reasons.
The cockatiel is a type of Australian parrot.
Cockatiel females are fertilized internally.
If I'm understanding your question correctly, your asking, "How much does it cost for a Cockatiel as a pet for your home?" This will cost you more than $100.00. The bird alone can cost over $100.00, then there is a cage, and bird food. Thecost for clipping your birds wings and toenails.. I would suggest you go to a pet shop and look around at the birds,cages and check out the prices.. If you do get a Cockatiel they can be a lot of fun. but be nice to them because they can and will give you a nasty bite on your fingers.
There is no such thing as the biggest cockatiel beacause all cockatiel are small but cockatiels are from the cockatoo family, so its relative ( the cockatoo) will be the biggest.
I would recommend you buy a baby cockatiel. That way it would be more likely to bond with you.
Every form of animal and plant life has a genus. The cockatiel's is Nimphicus.
Yes, a gray cockatiel and a lutino cockatiel can have lutino babies. The lutino coloration is a result of a recessive gene, so if the gray cockatiel carries the gene for lutino (which can be the case if it is a split gray), there is a chance that some offspring may inherit the lutino trait. If the gray cockatiel does not carry the lutino gene, all the babies will be gray or gray mutations, but none will be lutino.
1 human year = 4 cockatiel years
The average weight of a cockatiel is 93 grams.
