Heartbreaking to see the effects of beak and feather disease on these beautiful birds. We had a cockatoo visit us who was in the later stages, with no feathers left except on his wings and tail. So, while he could still fly, he had no protection from the heat or cold. We set aside a special bowl just for him and fed him daily for over six months. Sadly, one cold winter day, he stopped coming. I hope he didn't suffer too much in the end.
The cockatoo in the background may - in fact I'm pretty sure of it - have beak and feather disease. Do not call control, they will kill it without a second's thought and its partner will nearly die of grief, if it doesn't. Give it thyme, oregano, and plenty of nutrients. It will survive and pass a degree of immunity on to the young. But it needs help. Look out for it.
