In 2007, The Raptor Research Foundation published the 2nd edition of the Raptor Research and Management Techniques manual. This edition updates the 1987 edition of the Raptor Management Techniques Manual published by the National Wildlife Federation. Editors David Bird and Keith Bildstein assembled over 65 authors with extensive experience in their fields. Raptor Research and Management Techniques is the much anticipated and thoroughly updated version of the popular but long out of print Raptor Management Techniques Manual.
