::Toweling Method::
Some people don't believe in this but it's worked wonders for me and a lot of other people.
Toweling consists of wrapping a towel around your bird leaving only it's head on the outside.
This is what your bird should like look while toweled, hold the bird tight but not too tight to cut off their air and circulation.

Turn off all tv's sound etc in the background, sit down and hold your bird close to you. Pet his/her head and talk or sing softly. Do this every day for 1 week with each untamed bird, you should do this for no more than 15 minutes at a time, you can do it up to 3 times a day with little birds and 2 times a day for the larger types.
I hope this helps! You should start seeing improvement within 1 week.
