Wow - sounds amazing! Can't offer much advice on birding there as I've never been, but I'm sure you'll get lifers by the bucketload! Congrats on your Bittern - a cold snap in CA has forced our local Bitterns to forage out in the open, allowing magnficent views. Quite a bird!

Did so, thanks. It's incredibly helpful, as well as mouth-watering. My mind is filled with thoughts of Altai Snowcock, Koslov's Accentor, Saxaul Sparrow, Black-billed Capercaillie, Henderson's Ground-jay, Relict Gull, etc. etc.! Ordered "Where to Find Birds in Asia", but the more expensive "Field Guide to Birds in China" might have to wait until after Xmas.
