REPORT OF THE SECRETARY. 89 



a Brazilian ocelot, and a collared peccary from Texas were the only 

 mammals bought during the year. A few waterfowl were pur- 

 chased for the North American lake, including 2 blue geese, 4 

 Hutchins's geese, 1 canvasback duck, 3 lesser scaups, 2 gadwalls, and 

 4 male shoveller ducks. A few native birds of prey and a single 

 pine snake were also purchased. 



Transfers. — The Biological Survey of the Department of Agricul- 

 ture contributed to the collection some important animals taken for 

 various purposes by its field agents. The most valuable of these is a 

 lot of 6 little brown cranes (Grus canadensis) , a species not hitherto 

 exhibited in Washington. Other animals transferred from the 

 Biological Survey were 9 western box-turtles from the Chiracahua 

 Mountains, Ariz.; 2 great horned owls from Long Island, N. Y. ; 

 and a collection of small mammals, including species of Peronii/scus, 

 Mierotus, and Perognathus. In cooperation with the State Live- 

 stock Board of Utah, the survey also contributed, through Mr. 

 George E. Holman, 2 young gray wolves from Grand County, Utah. 



Captured in the park. — Two Virginia opossums and 30 small 

 birds, captured in the park, were added to the collection. Among 

 the more interesting birds so taken are examples of the European 

 starling and Baltimore oriole. 



Deposited. — The most interesting specimens received on deposit 

 during the year are a fine male Brazilian brocket from Mrs. Lindon 

 W. Bates, New York City ; and an American marten from Mr. Ernest 

 Thompson Seton, Greenwich, Conn. Eighteen alligators were car- 

 ried over winter for the Pan American Union. 



REMOVALS. 



The surplus animals sent away in exchange during the year num- 

 bered 54, of which 29 were mammals and 25 birds. The exchange 

 value was $3,017.50, as compared with $3,240.70 worth of animals ex- 

 changed in 1919. Most of the surplus animals were born in the park, 

 and the shipments included 6 bison, 3 barasingha deer, 3 red deer, 5 

 Japanese deer, 1 hog deer, 4 llamas, 2 guanacos, 2 gray wolves, 3 red 

 kangaroos, 4 peafowl, 3 golden pheasants, 10 Canada geese, 1 Man- 

 darin duck, 1 bald eagle, and G black-crowned night-herons. A num- 

 ber of animals on deposit were returned to owners. 



The death rate during the year, while slightly above that of 1919, 

 was nevertheless very low, and was approximately equal to that of 

 1918. The specimen of the rare brown hyena {Hycena orunnea) de- 

 posited in the park by Mr. E. S. Joseph in September, 1917, died of 

 acute pneumonia on November 14, 1919. The male Philippine deer 

 {Rusa philippinus) presented to the park October 17, 1904, by Ad- 

 miral Robley D. Evans, died of senile cachexia October 22, 1919.
