Large Raptors, Guangxi, China (1 Viewer)

[Barbets48]

This week, over the course of an hour saw several large raptors while birding in a forested hilly area near a reservoir (elevation 200m). I am uncertain whether there are 2 or 3 individuals/species represented:
Bird 1 was seen just a few minutes before Bird 2. Bird 3 was seen about 25 minutes later.
I'm especially wondering how to differentiate Oriental Honey-buzzard from Crested Serpent Eagle, as I think some of these birds are one of those two species.

They all look like oriental honey buzzard except 1(1). Small head, curved tail-sides.

Thanks Butty. The first photo was the same bird as 1(2) and 1(3) but I do admit it's kind of a strange angle and positioning of the bird, which may make it seem less distinctive.

I'm not entirely sure, but I wonder if bird 1 could be a Crested Serpent Eagle. For me, the head and tail shape seem to fit that better than Oriental Honey-buzzard. It's hard to make out any plumage details though.
Agree with Oriental HB for the other two birds.
