IV. BIRDS. 



1. The collection of Natatorial Birds, although much 

 restricted by the extent of water, contains many interesting 

 species, of which the Mandarin Duck, the Sandwich 

 Island Goose, the Ruddy Shieldrake, the Ashy- 

 headed Goose, the Magellanic Goose, and the 

 Black-necked Sw^an have bred for the first time, and 

 have been acclimatized in the estabUshment. 



Others are of extreme rarity, and exist in no other Viva- 

 rium ; as, for instance, the Red-breasted Goose, the 

 Australian Swan-Goose, and the Upland Goose.
