Moulting.
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.
The act of moulting (molting) the Arthropod exoskeleton is called ecdysis.

Preening is the process whereby a bird spreads oil from its oil glands onto its feathers. This keeps the feathers healthy & shiny, plus it is a way of removing dust, dirt, etc.
either molting or (and this is a joke. not for real.) DEATH! ha i really think its molting. a bird loses its feathers to grow new ones. it usually happens during winter to a bird that doesnt migrate and needs to be camoed. Hope it helped :)!
The feathers on top of a peacock's head are called a "head crest"
Yes, owing to their hard chitinous exoskeleton, arthropods are compelled to shed (moult) periodically in order to grow, a process called ecdysis.
The reverse process is called condensation.
