I don't have a pet galah - only some that visit the park at the back of my house. I hear them from time to time, and some like to nest in the trees in the park. I heard this one a day or so ago and took a photo of it.
Galahs are common here in Australia and many people have a pet one at home.
They can be very friendly pets and enjoy talking and dancing, as these videos show. I found them on YouTube. They are not videos that I did so I hope the folk that made them don't mind me promoting them.
