REPORT OF THE SECRETARY 89 



Birds 



Purchases and exchanges. — Anion*; the most important purcliases 

 during the year were a pair of maccaroni penguins, four pairs of 

 birds of paradise (Wilson's, Magnificent, King, and 12-wired), a 

 golden headed mynah, a pair of spectacled owls, and a pair of 

 European eagle owls, the last two being from the estate of Spedan 

 Lewis, the noted English aviculturist; and an imperial parrot se- 

 cured in Dominica through Mr. Stephan Haweis. 



A pigmy hippopotamus was bought as a mate to the one already 

 in the collection, and a male Molucca deer was also bought for the 

 same purpose. The zoo purchased a pair of sea lions to replace 

 those that died last year; a pair of jaguars, which have been lacking 

 in our collection ; and a black jaguar. The last is the third of its 

 kind to come to the United States, and is an exceedingly rare and 

 beautiful specimen. 



Important animals received in exchange during the year were a 

 pair of Molucca deer, and two pairs of axis deer, three keas, and a 

 rare wallaroo. 



REMOVALS 



The most serious loss to the collection was that of old Mom, the 

 female hippopotamus, who had been at the Park for 19 years, and 

 during that time had given birth to seven young, five of which were 

 raised. 



Causes of death. — When it has been thought that determination of 

 the cause of death of certain animals might be useful, the specimens 

 have been submitted to the Pathological Division of the Bureau of 

 Animal Industry for examination. The following list shows the 

 results of the autopsies :
