This is only a suggestion that will perhaps get some response from others. I have used Glycerin to preserve plants such as umbrella plant with gree dye added. If you want to save the natural colors,...
I usually hang the flowers upside down and allow them to dry. I also press them in picture frames. Either way they look and keep their colors. I have some from 2006 that still have their colors.
it depends if its a biting bird or a calm bird if it is biting you can wear gloves and put it on your hand or you can open their door and let it come out it self
