From this evening's New York Times web site:

Recordings Convince Skeptics That Ivory Bills Are Not Extinct
(http://www.nytimes.com/2005/08/01/science/earth/01cnd-bird.html?hp&ex=1122955200&en=a8794456c9d77392&ei=5094&partner=homepage)

The really encouraging aspect of this article is the opinion that the 
ivory bills sighted along the Cache River were birds searching for new 
territory. The core of the ivory population would seem to be in the 
White River refuge, and may be dispersing to find room.
