What kind of bird looses their feathers and why?
Disease - birds do not normally loose their feathers. When they change them it is called moult.Moulting is a process (like shedding in mammals) done regularly by birds, to replace old feathers with new, healthy feathers. This is normal. When a bird loses many feathers at once, it is usually due to the bird plucking out its own feathers OR a condition called French Moult, for which there is no cure.All birds may or may not lose their feathers. It is only when this happens to them and or they die.
