Obviously far from my normal quality photo, I uploaded this because the bird is the only of its kind on exhibit in the United States, and it took quite a bit of work from myself to get it. I spent two hours waiting for this bird to come out into the open, and only got it to do so when the room was empty for about 10 minutes. It was close to the path, and was scared to the tree shown here when I entered the room, but I am delighted to have seen it!
@CarLover I was told to look in trees in opposite corners of the aviary, rather than the tree you mean. Either way, I didn't see it until it flew up into this same tree.
