in general, and the Podargus in particular, when he says: "In 

 no other country is there a greater proportion of insectivorous 

 birds, and certainly none in which nocturnal species such as the 

 Podargi are more numerous." 



The Australian Roller (Dollar-Bird) has the family beauty, and 

 has a white circular patch on each wing, which shows clearly 

 when the wing is expanded during flight. At the Tallangatta 

 excursion a pair was working even after dusk near the school- 

 ground. Flying from the topmost dead branch, one bird sud- 

 denly closed its wings, and cut queer antics in the air. After 

 flying a considerable distance, it returned to its former perch, and 

 the mate set off. On the return of the mate the first set off 

 again, and so on. With their disagreeable, rough "treek treek," 

 and peculiar antics, they are conspicuous birds. It is our one 

 representative of a family most strongly developed in Africa. 



While Kingfishers are cosmopolitan (world-wide in distribu- 

 tion), yet the Australian region contains far more of these beau- 

 tiful birds than any other region. They are famous in legend 

 and story, and we owe to them the expression, "halcyon days" (Gr, 

 alkuon, a Kingfisher).
