Well I just Googled that question, I counts about the bars on a parrakeets head, the eye color, or the numbers on the bird's leg band. I got two parakeets myself and I got them in 2009. They are more than 8 month's old. :o)
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.
The spaces between the bars are probably too wide for a cockatiel. It would be able to get through them.
The cockatiel is a type of Australian parrot.
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.
Cockatiel females are fertilized internally.
hand raise means you have it from a baby and raise it your self so you can't hand raise a old bird
Yes, cockatiel eggs can be fertile. To determine if they are viable for hatching, you can candle the eggs by shining a light through them to see if there is a developing embryo inside. This can usually be done after about a week of incubation.
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
