138 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1961 



fed on dead mice, and before the eggs hatched the keepers began ac- 

 customing the adults to eating mice that had been cut up in small 

 pieces. These chopped mice, supplemented with cockroaches that had 

 been injected with multivitamins, were fed directly to the young birds 

 by the parents after the old birds had crushed them thoroughly either 

 in their bills or by rapping them against the tree. Thirty days after 

 hatching, the first bird left the nest, but they continued to be fed by 

 the parents until they were 2 months old. Before the first brood was 

 self-reliant, the female began laying eggs again, and two more young 

 were hatched on June 5. 



Following the procedure of previous years, all births and hatchings 

 are listed below, whether or not the young were successfully raised. 

 In many instances the record of animals having bred in captivity is of 

 importance.
