Captive propagation at the World Center for Birds of Prey is crucial to the success of both the Aplomado Falcon and California Condor restoration programs. These programs annually require large numbers of birds for release to the wild. The nature of these raptors makes breeding them in captivity both a labor-intensive and challenging effort. Factors such as nutrition, incubation management, and reduction of outside disturbances must be considered for successful breeding to take place. A tremendous amount of dedication, time, and knowledge is required by all involved to provide the best possible results.

2006 Results

Aplomado Falcon—In 2006, the Aplomado Falcon restoration program had 37 Aplomado Falcons lay 280 eggs, of which 157 (56%) were fertile. One hundred thirty-two eggs (84%) hatched and all the chicks survived to release age. Three of the ovulating falcons were first-time layers. No nutritional or disease-related problems occurred.

California Condor—Fourteen condors at the World Center for Birds of Prey laid 14 eggs of which 14 (100%) were fertile and 14 (100%) hatched with nine chicks surviving (see table). Two eggs were transferred to the San Diego Wild Animal Park where they hatched and are being raised for release in Baja, Mexico.

As of mid-December 2006, the world California Condor population totaled 284 birds. Of those, 148 were in captivity; the wild population included 61 in Arizona, 63 in California, and 12 in Baja, Mexico.

Staff
Captive propagation at the World Center is accomplished by Cal Sandfort (Aplomado Falcons) and Randy Townsend (California Condors) with assistance from Joe Burke, Emma Christensen, Meagan Kaiser, and Travis Rosenberry. Food production is accomplished by Amel Mustic, David Cline, and John Neilson. Facility maintenance is under the direction of Sam Davila.

Cooperators
Major financial assistance for California Condor propagation is provided by the U. S. Fish and Wildlife Service. Financial support for Aplomado Falcon propagation is listed within that project report.  Pathology and veterinarian support are provided by Meridian Veterinary Clinic (Scott Higer), the Zoological Society of San Diego (Bruce Rideout), Washington State University (Lindsay Oaks), the Idaho Department of Fish and Game, Wildlife Health Laboratory, Caine Veterinary Teaching Laboratory, and The Raptor Center (Pat Redig).
