But, umm, 3-right seems to have green on the back (as much as 4 does anyway).

As all the birds in the photos are just showing the upperparts of males I'm afraid you are going to have to log them as Frigatebird ? sp. Eye ring colour may have helped but the resolution isn't quite good enough. The basic metalic colour of the upperparts varies between oily green and blue, depending on the angle. For certain ID you need to see the underwing on frigatebirds, although pairs on the nest are reasonably straightforward.
