Captive Breeding at the World Center
for Birds of Prey
Propagate the required number of the best possible physically,
behaviorally, and genetically constituted raptors for release to the wild.
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.
West Nile Virus (WNV) arrived in the Boise area for the first
time, resulting in the deaths of two adult females that had been vaccinated in
2003 and five chicks that had not yet been vaccinated. We will maintain an
aggressive mosquito abatement program and refine our WNV vaccination and
evaluation program in future years.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.
