I found a clip of a bird on my computer. My Dad took it at San Diego zoo. I thought it was a blck drongo, but Now I thinks it's more like a Glossy mantled Manucode. I beleive that San Diego has the only one outside new Guinea. The picture is on the gallery. It's a still from a film clip, so it's not that good.
Sorry, I was looking in the wrong place. The bad news is I can't tell what any of the birds are, but I think you can discount a manucode. The pics I have seen show red skin around the eye. I'll do some more research tomorrow.
The tragopan has the head of a Blyth's but the body appears to be a Western Tragopan. A hybrid perhaps, or just a trick of the light causing a misidentification of a Blyth's. Still don't know anything about your other two. Sorry I can't help furthur.
I had a look in my birds of Indonesia book and then found that it looks like a metallic starling. Not an exciting speceis. Quite common in U.S Zoos.
