Why did my cockatiel pluck his feathers?

Question

When I was five or six, my family and I used to own a cockatiel. He was my brother's bird and I noticed that every so often the bird would pluck out his feathers to the extent that he would bleed. Why would he do this? Any time I tried to hold him on my finger, he would bite my finger so hard that it would start bleeding. Any advice would be helpful. No wise cracks please.

Answer 1

He did it because he was bored....theres another reason but i totally forget....google it google is a winner good luck :)

Answer 2

he did this to get rid of the old ones. you might need to put mite dust on him too sounds more like mites

Answer 3

Most times the bird is stressed. Have you just acquired the bird? Or have you moved? It doesn't take much to upset a bird.

Answer 4

its because when they first got the bird the loved it then as time went by they kinda forget about it.then from frusteration it started to pluck its feathers.aww poor cockateil.
