Yellow Marten I reckon

Yellow Marten I reckon was created by jack2964
Just got back from a trip to Phu Khieo Wildlife Sanctuary and I shot this one from a hide. I am primarily a birder so ain't quite sure about the correct ID for this.
Done googling and the pics all show them as black-faced. Perhaps mine is a juvenile?

It looks so, but unusual coloration, perhaps a juvenile? It looks quite slim too. Nice captures. :)

Wow - I had to go the books. Am still not 100% sure. In my own photos theres wide range of colour variation but nothing like that. That colour variation does seems to be evident (google search) in Malaysia and Indo though (a sub species). I did see two YTM's in Phu Khieo this weekend, but "normal" colouring. I think I would agree with you as PK is in the YTM's known range. Does seem juvenile, legs a bit short for a weasel YTM - face coloration does not fit the diagnostic of the other Thai candidate - siberian weasel.

Now I am wondering if its a yellow-bellied weasel (Mustela kathiah) - but out of its known range. Let me see if I can find someone who knows about Mustelids.

Woow that's a very cool sighting and amazing shots!

I would agree with Paul's suggestion (yellow-bellied weasel, Mustela kathiah), another option could be Back-striped weasel, Mustela strigidorsa though there seems no stripe visible on the back in your pictures.

Thanks to all for input.

I googled Yellow-bellied Weasel and the pics shown seem a good match but the distribution map has it out of range.
The text however (reproduced here) includes Thailand:

The yellow-bellied weasel is a species of weasel. It lives in the pine forests of Bhutan, China, India, Laos, Myanmar, Nepal, Thailand, and Vietnam. The yellow-bellied weasel is rated "Least Concern" by the IUCN Red List. Wikipedia

Scientific name: Mustela kathiah
Higher classification: Weasel
Rank: Species

So I think you guys are correct. Thanks again.

Congrats!

Just got a very helpful, detailed, informative and kind reply from Will Duckworth that I will forward to you.

He confirms that it is a Yellow Bellied Weasel, and :

"This is quite an important record. Phu Khieo is outside the known Thai range, which is restricted to the northern highlands and western mountains (see Fig. 5 in Supparatvikorn et al., attached) "

Thanks for the confirmation btw.

I added it to the range map here;

www.thainationalparks.com/specie/yellow-bellied-weasel

.. together with additional data from this publication;

www.siamese-heritage.org/nhbsspdf/vol051...ikorn_DiscoveryO.pdf

I also added a "Site notes" section below the main copy about your finding, I will gladly add your name if you let me know. :)

Cheers,

Rushen
