88 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1921. 



The birds received in exchange include also 2 sun-bitterns, 2 black - 

 necked swans, 2 Cape Barren geese, 4 upland geese, an Indian jabiru. 

 a sarus crane, scarlet ibis, yellow-wattled lapwing, and numerous 

 small birds of various kinds. Five tree iguanas and a large boa con- 

 strictor were received from South America. 



Purchases. — Only 9 mammals, 45 birds, and 9 reptiles were pur- 

 chased during the year, as the limited funds available would not per- 

 mit of much expenditure for stock. The mammals purchased were 

 4 armadillos, 2 gray foxes, a Florida lynx, a pigtailed monkey, and 

 one bandicoot. Birds purchased were mostly hawks, owls, and water- 

 fowl at low cost, but some exceptionally valuable specimens were also 

 obtained. A specimen of the rare kagu from New Caledonia Island, 

 and of the Nepalese paroquet from India, represent species new to 

 the collection. 



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

 ture continued its contributions to the collection. Two young pumas 

 or mountain lions from the Kaibab Forest, Utah, through Mr. 

 George E. Holman; and three young pumas from Arizona, through 

 Mr. M. E. Musgrave, were among the most valuable transfers from 

 the survey. Mr. Vernon Bailey, chief field naturalist, contributed 

 an interesting collection of small mammals, including various species 

 of pocket mice, kangaroo rats, spermophiles, and other rodents. Two 

 little brown cranes from Nebraska were also transferred from field 

 agents of the Biological Survey. 



Captured in the park. — Five birds and 2 reptiles, captured within 

 the National Zoological Park, were added to the collection. 



Deposited. — A few parrots and other birds and one reptile, needed 

 for exhibition, were accepted on deposit. Owing to the greatly 

 increased work at the park and the small force of keepers employed 

 to care for the growing collections, it has been necessary to refuse 

 birds and mammals offered on deposit, and subject to recall by the 

 owner, unless the specimens represent species which add distinctly 

 to the exhibition value of the collection. 



REMOVALS. 



Surplus animals sent away in exchange for other stock during 

 the year included 62 mammals, 45 birds, and 12 reptiles. Most of 

 the surplus animals were born in the park. Among the specimens 

 so exchanged were a young hippopotamus, 5 American bison, 1 yak, 



1 East African eland, 1 Indian antelope, 4 llamas, 2 American elk, 

 11 European red deer, 2 Japanese deer, 2 red kangaroos, 2 European 

 brown bears, 2 African lions, 1 mountain lion, 4 gray foxes, 2 wolves, 



2 coypus, 3 rhesus monkeys, a number of waterfowl, peafowl, and 

 other birds, and 12 alligators. 



A number of animals on deposit were returned to owners.
