My cockatiels make strange sounds?

Question

I have a male and female, my male is a white and grey coloured which looks really cool, but it keeps making strange sound like a gargling noice which sounds like someone is strangling the poor thing, this only happens when he drinks water.

And the female is worse, in the morning she keeps singing and whistling which is good for my beauty sleep.Why do they both make strange sounds?

Answer 1

its nature. let nature do its thing. and your lucky you got a singing female, most female cockatiels wont sing. let nature do its thing. if you want to sleep at night but a thin blanket over them. and they will sleep much better too. thats what i do. basically there happy.  

Answer 2

You're SO lucky! I LOVE cockatiels. I used to have two. My male cockatiel never went through such things. So I'd suggest bringing the poor guy to the vet? It could be an infection or something in the throat. As for the female; thats normal =)
