SECRETARY'S REPORT 39 



time permitted, Dr. Humphrey continued his studies of plumage suc- 

 cession in birds and on the distribution, ecology, and classification of 

 Patagonian and Brazilian birds. At the close of the year he was 

 back in Brazil. 



From the beginning of December 1963 to the latter part of March 

 1964, George E. Watson, associate curator of birds, served as official 

 United States representative (observer) with the Chilean- Antarctic 

 Commission. During delays in Chile for ship repairs and for the ice 

 to break up he was able to spend 13 days in December at Peulla, Llan- 

 quihue Province, observing and collecting forest birds. During 

 another delay of 22 days in January-February at Puerto Williams, 

 he was able to make a catalog of birds breeding on Navarino Island 

 and to collect specimens, among which are several important additions 

 to the national collections. Mr. Watson's observations of birds made 

 on shipboard in Antarctic waters will be useful in preparing an identi- 

 fication guide to Antarctic birds which he has planned. Upon his 

 return from Chile he completed his doctoral dissertation dealing with 

 ecology and evolution of passerine birds on the islands of the Aegean 

 Sea and received in June the Ph.D. degree from Yale University. 



Dr. Richard L. Zusi, associate curator of birds, spent a week in 

 November at the University of Michigan working on three manu- 

 scripts, which he had begun there, and consulting with Dr. R. W. Storer 

 concerning their joint research project on the myology of grebes. 

 From January to April he was in Dominica studying birds as a par- 

 ticipant in the Bredin-Archbold-Smithsonian biological survey of that 

 island. 



In continuation of his long-term field work on the birdlife of the 

 Istlimus of Panama, Dr. Alexander Wetmore, honorary research asso- 

 ciate and retired Secretary of the Smithsonian Institution, concen- 

 trated his efforts from January through March in Darien Province, 

 mainly in the heavy rainforest adjacent to the Colombian boundary. 

 The results were most successful, for both specimens of and observa- 

 tions on species that have been little known in Panama were obtained, 

 and several new records of South American birds not previously 

 recorded in the area were established. 



Dr. Herbert Friedmann, honorary research associate and former 

 curator of the division, continued his work on brood parasitism and 

 completed a manuscript dealing with evolutionary trends in the avian 

 genus Glamator. 



Herbert G. Deignan, honorary research associate and former mem- 

 ber of the division, was in Washington from mid- January to late April 

 studying birds from Formosa in the Naval Medical Research Unit 

 (NAMRU) collections and those from Viet-Nam and Cambodia col- 

 lected by Bernard Feinstein, former museum specialist in the division.
