I've had my cockatiel, Buttons, for almost a year and I'm still learning! (Wow, its already been almost a year! )

Like Logan said, they are VERY messy! Buttons' cage is about 4 feet away from my bed and am always finding seeds in it! He also tends to poop in his water, so I clean it out 2-4 times a day.

Cockatiels do need a lot of attention, but when they 'call' you over and beg to come out, who can resist?

Good luck getting a tiel!
