I do hope you are able to find a larger, feathered friend for Henry!
Wonderful you've taken interest in looking at the birds we have at our shelter, as well!
You may have seen this already, but thought I would provide the link, in case you have not, on adopting Parrots from us! It should go right to the Parrot part, but if not, you can click on top for it to bring you to their part!
[link]Whether from us, or another, I again hope you are able to find Henry a friend, and he finds his friend to be just great!
