162 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1957 



graphed in color for a permanent file of 2-x-2-inch slides. These will 

 be used on the island as orientation and identification aids and as a 

 record of habitat conditions. 



The major ornithological event of the year was the discovery in 

 January of a young king vulture (Sarcoramphus papa) , still largely 

 covered with down, on the forest floor. Heretofore little was known 

 of the nesting and young of this huge spectacular bird. Also of note 

 was the return of the oropendolas (Zarhynchus wagleri) to a con- 

 spicuous nesting site in the laboratory area. Twenty nests were con- 

 structed above the Kodak Test Table Building. 



Principally through use of mist nests, the number of species of 

 bats known to occur on Barro Colorado Island was increased from 

 17 to 28. These bats included two species apparently not previously 

 recorded for Panama (Centurio senex and Micronycteris hirsuta). 

 Including these, and deleting a few old, unconfirmed, or unnatural 

 reported occurrences, the number of species of mammals known to 

 occur on Barro Colorado Island is 70. 



FINANCES 



Trust funds for maintenance of the island and its living facilities 

 are obtained by collections from visitors and scientists, by table sub- 

 scriptions from institutions, and by other donations. The table sub- 

 scriptions were greatly appreciated as they helped to defray the cost 

 of maintaining the island facilities. Organizations that continued 

 their subscriptions, and the amounts donated, are as follows: 



Eastman Kodak Co $1, 000. 00 



New York Zoological Society 300.00 



Smithsonian Institution 300. 00
