38 BIRDS OF AUSTRALIA. 



coast ; but SO little has at present been ascertained respecting 

 its economy, range, and habits, that its history is nearly a 

 blank ; even whether it is migratory or not is unknown. 

 That it breeds in the brushes of the district above-mentioned 

 is certain ; for I recollect seeing a brood of young ones in the 

 possession of Alexander Walker Scott, Esq., of Newcastle on 

 the Hunter, a gentleman much attached to the study of the 

 natural productions of Australia. These young birds differed 

 but little in colour from the fully adult specimens in my 

 collection, except that the transverse markings of the breast 

 were darker and of a more arrow-shaped form, which markings 

 become fainter and more linear as the bird advances in age. 



The sexes present the usual difference in size, but in colour 

 and markings they closely assimilate. 



All the upper surface grey ; throat and all the under sur- 

 face white, crossed with numerous irregidar grey bars ; cere 

 yellowish orange ; feet yellow ; bill and claws black. 



The irides of the young are brown.
