It is undeniably annoying to return to this thread only to find that the latest post is yet another person saying something along the lines of "Is it him?", and discussing what might have happened to him achieves nothing.
Can someone lock this thread, please? It is now plainly obvious that the OP does not wish to continue with this topic, and if there was any good news on the matter, it would have been stated weeks ago.
I hate to say this, but I would not hold my breath. Two of my rabbits disappeared when they decided that staying where they should have was not good for them, and because there are so many more predators in America, that just makes matters worse.
Are there any chicken breeds that have elongated bills? The bird in question reminds me of a Strasser Pigeon (below) in this way.
