tributed one is the Maned Goose (Wood Duck), 

 map 44, b. It appears to be a duck with a miniature 

 goose-bill. 



The Black Swan is an elegant and popular bird, 

 probably the oldest known Australian bird on 

 record. 



The young are plain grey. If a nesting swamp 

 dries completely, the young are marched overland 

 to another marsh, in the sight of their parents all 

 the time. In Queensland the swan breeds three 

 times in a year, and the first brood of young is 

 driven away before the parents settle down to the 

 care of the second. More serious trouble for the 

 young is found in the number of Golden Beaver- 

 Rats which destroy them. 



CORMORANTS 

 (Plate 2, Fig. 45) 



1. Australasian. 



2. Extra Australian. 



The family is a very uniform one, variable only 

 in plumage colour. This is most marked in the 

 disposition of the black and white, and minor 

 pigment colours of the bare skin about the head. 



Upon examination of the hard tissues of the 

 family, it is found to be closely related to the 

 Gannets, Tropic Birds and Frigate Birds; all won- 

 derful things in feathers.
