Presently the largest and most astonishing bird in the skies of North America, the California Condor was one of our most highly endangered species by the 1980s, when it persisted only in a region just north of Los Angeles. By the late 1980s it endured only in captivity, but it has since been returned to the wild in selected regions. ...

The California Condor (Gymnogyps californianus), North America’s largest avian scavenger and one of the largest flying birds in the world, is an iconic species by any measure (figure 1). Although commonly depicted as a bird of southern California and the desert Southwest, condors once soared the skies of the Pacific Northwest ...

Fossil evidence suggests that California Condors were widely distributed in North America during the late Pleistocene,1 with records from Oregon, California, Nevada, Arizona, New Mexico, Texas, Florida, New York, and Mexico (L. H. Miller 1910a, 1910b, 1911; L. Miller 1957; Wetmore 1931a, 1931b; Parmalee 1969; Simons 1983; ...

Whether or not condors historically were migratory or resident in the Pacific Northwest has been a matter of debate (Koford 1953; S. Wilbur 1973, 1978) and has implications for planning future reintroductions and establishing connectivity between populations. In his seminal work on the California Condor, Carl Koford (1953) hypothesized ...
Chapter 4: Timing and Causes of the Condor's Range Collapse

The California Condor has sometimes been portrayed as a Pleistocene relict or a senescent species that has been in a state of population decline for thousands of years (e.g., L. Miller 1942; Pitelka 1981). Despite a significant range contraction and the concurrent extinction of several large avian scavengers (including several condor species) ...
Chapter 5: Summary and Future Outlook

The long absence of the California Condor from the Pacific Northwest and the crisis situation of condor conservation in the late twentieth century have, until recently, resulted in a lack of focus on recovery efforts in the Pacific Northwest. It is our hope that by articulating the history of the California Condor in the region we might inform future dialogue ...
