Those added do not include Yellow-legged Buttonquail, David, just in case you were thinking of buying the revised edition just for that!
This really is a magnificent piece of work - about the only suggestion for improvement I can make is to say that the challenge is still on for our photographers to get reasonably good shots of Mallard in HK. The Ho Chung thing is still in and the headshape of the Lamma bird certainly looks a bit odd to me (as well as being a funny date and location).
Amazing value at $225!
