DEPARTMENT OF BIRDS.

The past year has been one of quiet maintenance of the 

 collection, and in spite of the fact that no collecting expe- 

 ditions of importance were undertaken, nor large consign- 

 ments of specimens received, there has been no falling off in 

 numbers or general condition. On the other hand, every cage 

 and runway being filled, it has not been possible to materially 

 increase the collection as a whole. The balance of species is 

 constantly shifting, and the many forms which are represented 

 by only a single specimen make it necessary to replace them at 

 once with some other, whenever a death occurs. The passing 

 of new protective laws, and increased zeal in the enforcement 

 of those already in effect in various countries, make it ever 

 more difficult to secure desirable foreign species. This is as 

 it should be, but it will result ultimately in forcing us to send 

 direct to foreign countries for special shipments. Our South 

 American exhibit is slowly diminishing, although there are a 

 number of birds still surviving from the expedition to British 

 Guiana, made five years ago. 



Late in December the Assistant Curator made a short trip 

 to northern New York, for the express purpose of securing 

 specimens of the pine grosbeak (Pinicola enucleator leucura). 

 This is the first time in several years that this eccentric migrant 

 has appeared in numbers, and the species has not been repre- 

 sented in the collection for six years. A score of the grosbeaks 

 were trapped and are now on exhibition, tame and feeding well. 



Early in the summer an outbreak of duck cholera occurred 

 on the Wild Fowl Pond. As in 1911, it was directly due to a
