I love Bourkes too. I am particularly fond of our little Musky man we hand reared him six years ago, and he is one of the favourites when people come to visit.
Musky can whistle an unlimited amount of tunes, and so clear that you can sing along with him. I love him so much, that I went out and bought two more Pink Bourkes and I also bought a normal pair, and they all have the most beautiful eyes, and the most beautiful nature to go along with those eyes.
