Vietnam (Central)- forest birds to ID (1 Viewer)

I have had a couple of mornings out in some forest about 40km west of Nha Trang and have a couple of birds I cannot ID and a someI would like confirmations for.

(1) Confirmation that this is a Black headed Bulbul (and not a gayeti subspecies of Sultans Tit)

(2) confirmation that all Three of these birds are Asian Fairy Bluebirds.

(3) Are these a Woodshrike? To me, the size suggested Greater woodshrike, but there is no white rump patch. Does this mean they must be common woodshrike (or are there subspecies of Greater wooshrike without the white rump patch? (or am I way of track...?)

(4) I have no idea what this red headed bird is. Images in Robson suggest either grey sided or chestnut capped bush warbler, but I am not happy with either ID (and neither is suggested to be in this region). Any ideas???

(5) This guy looks familiar, but cannot place it.

Thanks all in advance

1. Neither. It's black-crested bulbul (crest is largely hidden behind the branch).
5. One of the tailorbirds?

Hi Wayne,

1. Is Black-crested as BuckeyeAZ says
2. Yes Asian Fairy Bluebird
3. Common Woodshrike
4. Chestnut-capped Babbler
5. Dark-necked Tailorbird due to the yellow vent

1. Black-crested Bulbul
2. Asian Fairy Bluebird
3. Large Woodshrike
4. Chestnut-capped Babbler
5. Tailorbird...hang on I'll look it up!

Ah cross-posted with Viator. Yep, agree with Dark-necked Tailorbird, but need convincing that it's CWS rather than LWS. I can find some images of LWS with dark-looking iris, but none of CWS that don't show the broad white super behind the eye.

Thanks guys. Helpful as always!!!
