The NACWG board and membership express their appreciation to the Platte River Whooping Crane Maintenance Trust (now The Crane Trust, Inc.) for contributing office space and equipment, thereby providing an unofficial base of operations for the Working Group during the first decade of its existence.
Len Schumann and the Eastern Sandhill Crane Group graciously allowed us to appropriate the name of their former newsletter, The Unison Call, for our own.
Lisa Beth Daly provided the artwork for The Unison Call masthead.
From 2003 to 2008, space for this North American Crane Working Group website was graciously provided by the International Crane Foundation.
We are also especially grateful to Michael Forsberg, Dr. Richard Reading, and Gerard Tournebize for generously providing photos for the website.
