CROWNED EAGLE IN CAPTIVITY

ƒ Commonly presented to rehabilitation centers and zoos

ƒ Recovery and release to the wild of these birds is sometimes
  possible, but many of them are not able to be fully rehabilitated

ƒ More than twenty crowned eagles live in captivity in different
  rehabilitation centers and zoos of Argentina

ƒ Used for ex-situ conservation programs
   ƒ   Rehabilitation
   ƒ   Captive breeding
   ƒ   Biomedical studies
   ƒ   Education
   ƒ   Recovery programs

  ƒ   IBAs monitoring
  ƒ   Habitat conservation
  ƒ   Develop action plans for conservation at province,
       national and regional level (BirdLife criteria)
  ƒ   Build local capacity for conservation
  ƒ   Enforce legal protection of the species
  ƒ   Intensify educational programs
  ƒ   Organize awareness campaigns to limit hunting
       near key populations

  ƒ   Economical, cultural and social shifts               26
Conservation Measures Proposed
ƒ Ex-situ
  ƒ   Recovery and rehabilitation of injured eagles
  ƒ   Welfare
  ƒ   Biomedical studies
  ƒ   Educational activities
  ƒ   Genetic diversity
  ƒ   Management
  ƒ   Captive breeding

A ¨task force¨ for the study and conservation of this eagle in
   Argentina - involving researchers from different disciplines
   along the country - is in formation

Aims are to address and evaluate the in–situ and ex-situ
  conservation strategies for this eagle and to elaborate a
  national conservation program

A Crowned Eagle workshop will be held in Buenos Aires, March
  2007, in order to discuss the conservation status of this
  species, prioritize and establish research and conservation
  strategies, and promote collaborative efforts

                                                                  28
