Population Statistics
Captive
22.18 in AZA
25.22 including
non- AZA
Max pop was 79
birds in 1983
Wild
Est 20,000-50,000
Captive Breeding Populations-
What’s the issue?
Aging captive population
Goals of AZA institutions
Difficulties
Unsuccessful replication at institutions that
had success
Strong pair-bonds and behavior
Reproductive restraints of species
Success Stories
Jurong Bird Park,
Singapore
1980
Audubon Park and
Zoological Garden
1988

Success Stories
Sacramento Zoo, 1989

Strategies to attempt
Varying diet and frequency with minimal
nest disturbance
Diet: Figs, non-figs, animals
Nesting success coincides with period of
max fruit production
Nest disturbance was number one reason
for nest abandonment
Strategies to attempt
Mimic wild environment
Multiple: bird, nest cavities, nest
location, nest materials, food locations
Pros Cons
• Natural expression of
behaviors
• Free mate choice
• Increase reproductive
success
• Genetics
• Aggression
• Density
• Space
Strategies to attempt
Artificial insemination and Semen collection
Recovery of avian populations
Massage technique
Requires training to minimize stress
Must have all other environmental factors in
place for success
Avenue for future research
Wrap-up
Aging captive population
Unsuccessful attempts to create a
sustainable captive population has been
an ongoing goal of AZA institutions
Suggested strategies have the potential
to increase captive populations
Questions? Thank you!!!
