This blog is possible only because of the work and endeavors of librarians from many institutions. The librarians at Waidner-Spahr Library (Carlisle, Pennsylvania) continue to be especially helpful.

I also offer my appreciation to those who trade in old books, journals, maps, and other publications. These dealers help to make sure that these materials are not forgotten and lost.

The California condor and standing dead tree logo images were created for Pseudogryps by Rosa Chung and Chris Law, whose Minimalist Animal Art is available at TheVegesaur.

I am grateful to the thousands of people who have worked to insure that California condors are alive today and flying free. Many of these dedicated individuals are employed by federal and state government agencies, including the Fish and Wildlife Service, Forest Service, National Park Service, Bureau of Land Management, California Department of Fish and Wildlife, and Arizona Department of Game and Fish. Still more individuals are employed by non-governmental organizations that are funded by charitable contributions. Please support these organizations, including:

Los Angeles Zoo
Oakland Zoo
Oregon Zoo
Peregrine Fund
San Diego Zoo

Santa Barbara Zoo
Ventana Wildlife Society
