some are and some arent dont worry.
Yes
When cockateils bite them selves they are actually just grooming their feathers to clean themselves
they dont they dont
go to the vet NOW!
all birds are warm blooded
Their are native to Australia. Of course, their now kept as pets all over the world. The US, and I would imagine many other countries, require all pet cockateils to be born in captivity. That's the reason for the bands.
no that's not that probably means its sick
Two cockateils CAN be kept in the same cage. If you dont wat eggs, be sure they are the same sex.
yes but you ALSO feed it special food
because in the wild that's the time they eat and play
sorry no it would not they would peck out each others eye balls!
Males definitely. The female cockateil is just lucky if she starts to tweet.
Yes of course, mine loves it! :p They are actually not big fruit eaters so you might be wasting your time and should not be in the form of sauce but natural. See below-
