It was in a state of depression and was losing it's feathers, It was very young and it's cage had literally been thrown around the room and the bird had almost had it's wings ripped off, the owner (an old lady with Dementia) was throwing it about and trying to kill it, but because of her mental illness, she didn't realise what she was doing, and had to be given up.
Unfortunately, nobody had the time for it, and it was eventually given to us, because we knew that it would have a same home where we were.
Unfortunately, He seems as though his bluffing session wasn't too easy for him at the home, so he is a very frightened and jumpy bird, and he always bites, mainly when he feels frightened.
It can crawl up my arm, and I have even stroked it all the way down to the start of his tail, but he still gets very scared.
He is green, and very greedy!

We try our best for him, and I hope we've done the right thing.
