Cockatiel's are very difficult to age. You can only be accurate about their age if you've had the bird from a baby. The only way a cockatiel can be aged is as a juvenile, adult or senior.
I have five of them - it is typically through age and shedding, nothing more.
It's not recommended to have a cockatiel in your house with a child who's age is less than 5. Maybe you should wait a few more years.
The cockatiel is a type of Australian parrot.
Cockatiel females are fertilized internally.
You can wean a baby cockatiel when they are at least eight to nine weeks of age.
Your cockatiels should be at least a year old before you start breeding them to prevent ill offspring.
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.
A female Cockatiel will start to lay eggs from 5-6 months of age, and can continue laying eggs until about 10 years of age. !
Every form of animal and plant life has a genus. The cockatiel's is Nimphicus.
The oldest living cockatiel died at the age of 36.
