This story is a sad and good at the same time. I learned about it from the Runet: pikabu.ru/story/prodelki_zhelt…
You can see the photo of this bird in the link.
This is Kesha. This parrot was saved from the really bad owner. It was supposed to entertain the visitors of the sanatorium. The bird was caged in a draft and could not rest from the public. One day a kind woman drew attention on the feather plucking and stress of the bird. She bought this white cockatoo and brought it in her family. Also she bought a girlfriend for Kesha - Kocko. Life of the bird became more calm and happy.
Now Kesha looks better. But the feathers havent't recovered completely. So I decided to draw Kesha as healthy and beautiful parrot. I think, cockatoo will be all right in the future.
