I'm an about to be cockatiel owner ... Do you keep each bird in a separate cage?
My males (RIP) seem to have done a bit more singing than others here. Like alllll the time. The shrieks, ,which can be male OR female, are pretty loud. We had their cage by the TV in the family room for awhile - the birds tried to out-yell the TV! Finally they got their own room!
I now have 4 girls. They are all different. But all quieter than the males, except Clint was very quiet but he was like 28 when we got him.
1. Torrie, gives the loud whistle/scream when we go in or out of the house. Demands scritches, you can see her on my Youtube Bird Babble. (Moody Cockatiel is the video)
2. Spirit, quietest bird in the world, just wants to sit on your right hand. No, not your shoulder or lap, your hand so you can't get any work done.
3. Pearl, new about 2-3 months ago... supposedlly 1 year old... starting to like being on her person a lOT. She will scream if she can see me and isn't on me. I occasionally hear them all chattering together.
4. Pippa, sometimes will make the boy whistle but is a girl. She is noisier than Spirit, but only calls out occasionally. Wants nothing to do with people.
If I were to only have ONE and wanted cuddly or a shoulder bird.... I would get a girl.
If I were to only have one and wanted to teach whistle songs... I would get a boy.
