It is known that birds' feathers would fall off and replaced with new ones. Species with a breeding plumage would change their feathers two times each year, while for others the change may be gradually. This is called moulting. For some Common Myna, it may occurs all at once at the head and neck, and the bird become bald. Though it's look may be strange from others, but it is still allowed to associate in the flock.

This Barn Owl was taken care by a gardener in Queen's Park.
It's a pity, is'n it? A night bird, it often sneaks to sleep in a barn during daytime. And that's the way it is prone to be trapped. Keeping a protected species is prohibited anyway. Maybe, the bird might be found in a sick or injured condition and thus temporarily retained for healing.
Visiting the place again the day after, the bird was not present, empty case. Good luck Barn Owl!
