I've just received NHBS Ornithology Newsletter - September 2011, which features Birds of Argentina as due in October! .......
The NHBS website lists the individual volumes as cancelled. So only the two-volume set seems to become available, whenever that will be. They still list it for 2011 as well.
You can always count with the "Birds of Argentina" from Narosky & Yzurieta. Drawings are not the best but I must tell I love this guide.......Julián
Welcome to the forum. It might be jumping the gun a bit (although even the best athletes do it!), but don't forget to tell us about your trip to Argentina when you get back. BirdForum also has a Vacation Trip Report forum.
You can always count with the "Birds of Argentina" from Narosky & Yzurieta. Drawings are not the best but I must tell I love this guide. It was my first bird book when I was six and now I call it "the Bible". The birds description are mostly very accurate and once you get used to the guide is very easy to use. The last edition comes with birds photographs and a cd and is not expensive at all (in Buenos Aires it will cost you around u$s 50).
If you need any help in your trip I will be glad to help you.
This guide has often been criticized, but I agree with Julián that it is much better than its reputation. In most cases, I got along very well with this book in 2005/2006. One feature that I found extremely helpful is the fact that the most important distinguishing features are marked in bold face. I had the "de la Peña" FG (Birds of Southern South America ...) along as well, but I used it very occasionally only. Not sure whether the photos in the new edition of Narosky & Yzurieta will be of much help. They may rather clutter up the pages, I'm afraid.
I strongly suggest, however, that you get the book now to prepare for your trip. Do not wait to get it on arrival or speculate that just maybe the Pearman volumes will be out in time for your trip. It is most helpful to spend considerable time in advance with the appropriate books. In my case, I had written the corresponding plate numbers of the "de la Peña" book to the entries in the Narosky book, as "of course" the sequences and sometimes even the names differ.
Do you know which edition have photograhs and CD?
The edition with pictures is the 2011(you can find it in the "books" link from this page). I have seen the pictures and most of them are quite helpfull.
If you need any information of Argentina just ask.

There seem to be two editions, 2010 and 2011, but they both have the photos, and a DVD with bird sounds that might make me buy the book again if I make it back to Argentina.
.....I've bought "Birds of Chile: Including the Antartic Peninsular, the Falkland Islands and South Georgia by Alvaro Jaramillo, Peter Burke and David Beadle" .......Carsten
