Cockatiel sexing

what you can do is get a peice of string and loop a ring or something slightly heavy on the end. then hold it perfectly still above the cockatiel (holding onto the end without the ring) it will start swinging after a couple of seconds still holding the string above the bird, wait about 30 seconds, if the string swings in a circle its a girl if the string swings in a straight line, its a boy ... if that makes any sense at all it has always worked for me...

If you can keep them from running away from the strange thing hanging over their head or attacking it.

You have to see cockatiel behavior on this cockatiel video. I never saw something like this . When it's owner clapping by hands, he shaking hes head up and down like crazy. Awesome...
Actually the owner of that funny cockatiel is friend of mine.

p.s. - Also you can see some of his cockatiel photos and listen some cockatiel sounds. If you are looking for details about breeding cockatiel informations take a look here.
Enjoy....
