SECRETARY'S REPORT 233 



Two scientists were added to the permanent staff last year : Dr. Rob- 

 ert L. Dressier and Dr. Neal G. Smith. 



Dr. Dressier continued the studies of Orchidaceae which he has 

 been pursuing for some years, supported by a National Science Foun- 

 dation grant. In connection with this project, he made short field 

 trips to Costa Rica and the Cayman Islands and studied specimens in 

 the collection of the Missouri Botanical Garden. He also visited 

 Miami to observe various species of orchids in cultivation there and 

 to consult with Dr. C. H. Dodson, with whom he is collaborating 

 in a study of pollination. 



Dr. Smith began field work on the behavior and ecology of sev- 

 eral groups of birds. He also visited Virginia Polytechnic Institute 

 to secure information on histological and laparotomy techniques, 

 studied collections of plant materials in the Gray Herbarium and the 

 U.S. National Museum, studied the zoological collection of the U.S. 

 National Museum, and visited the New York Zoological Society to 

 obtain information on keeping and raising certain species of birds 

 in captivity. 



Dr. Moynihan continued studies of the signal patterns of platyr- 

 rhine monkeys and New World "nine-primaried" songbirds, and be- 

 gan a long-term investigation of geographical variation in social be- 

 havior among Andean birds, supported by a grant from the National 

 Science Foundation. This last project necessitated field trips to Peru 

 and Bolivia. Dr. Moynihan also attended the Eighth International 

 Ethological Conference at The Hague in September 1963, studied col- 

 lections in the U.S. National Museum and the American Museum of 

 Natural History, and visited Harvard University for discussion of 

 bioacoustical problems and techniques.

BUILDINGS AND EQUIPMENT 



Maintenance activities on Barro Colorado Island continued as usual. 



Installation of the electric cable from the mainland to the island was 



delayed by various factors, but it is hoped that the work will be com-
