Mystery bird, Dalat, Vietnam

Can anyone ID this one? Could it be Black-headed Sibia? Can't think of anything else that fits.

Male Grey Bushchat.

I wouldn't normally question you Grahame, but this bird was definitely not Grey Bushchat. I coincidentally saw a pair of Grey Bushchats this afternoon, my first encounter with the species, and the bird in the picture was very different. For a start, the mantle was darkish chestnut. I have also ruled out Black-headed Sibia as the form found in Dalat is robinsoni, which is completely different to Dark-backed Sibia. I now think this bird must be a White-cheeked Laughingthrush.

I was almost swayed and thought I had 'lost it' and completely misjudged the birds size but no....the first image ain't no Laughing Thrush, the structure is completely wrong. In any case, White-cheeked has a black gular stripe which your bird clearly does not. And the flanks are grey; warm buffish-brown as in WCLT.

So, why is it not a Grey Bushchat? Non-breeding males/imm males at this time of year can show extensive rich brown tones to the upper parts.

In the first image you can just make out the white brow and you can also make out dark centres to the upper parts. In addition, the tail pattern fits Grey Bushchat; white in the tail sides whereas in WCLT the tail feathers are broadly tipped white as can be seen in link provided.

And here's a bird showing the extent of brown in the upper parts; this is gradually lost through wear.

Grey Bushchat for sure

Agreed.

It certainly looks like one from the photos. It's just that I can't match the image of this bird in my memory to any image of Grey Bushchat. I spent yesterday struggling with tricky Phyllocs and Seicercus warblers plus numerous other unfamiliar species and perhaps my brain got so overloaded, I've conflated my memory of this bird with another.... You're definitely right in saying it's not a White-cheeked Laughingthrush - I saw one today and it was completely different, so I guess it must be Grey Bushchat. Thank you for taking the time to point out the error of my ways!
