Spotted this cockatoo in our Botanical Gardens. Certainly looks a bit troubled by the lack of feathers around his head but he was able to fly though :)
Oh dear. I feel bad for him. Surely he's old and that's why his feathers are thinning. Lord knows, my hair is sure not as thick as it used to be. Smile.
Maybe he belongs to that cockatoo feather head cult. I was at a vet a few months ago and they had one who had no feathers at all - he would pluck them all out with his beak. Not sure how one would do that in your case here, though. Hope he gets better.
Love your title.
