Concerns about the world's biodiversity are not new, but the BirdLife International organization has taken on an important challenge by documenting the state of the world's birds via the important research papers featured on this site. The news they offer is not terribly encouraging, but these documents will be important tools for anyone interested in these pressing issues. The primary work here is divided into four sections that includes an introduction, along with three additional sections that cover why birds are declining, the current state of information about bird populations, and what can be done to improve the status of birds around the world. Some visitors may also wish to utilize the "How to use this site" area if they are experiencing difficulty navigating the various features here. The site is rounded out by two very impressive reports from 2004 and 2008 on the state of the world's birds. Both reports are available in English and French, and the 2008 report is also available in Spanish.
