VICTORIA 119 



found on the Keilor and Werribee Plains. When 

 the ordinary weather returns, the birds will keep 

 to the northern side of the Divide. 



DISCONTINUOUS DISTRIBUTION 



Scrub-Birds. 



East West. 



Colour Pattern. 



An example of the station or broken distribution 

 of a species is given in maps 49 and 50, and at the 

 same time it is a good case of eastern and western 

 representation of the same bird. These species 

 also indicate coastal habitat extending from the 

 sub-tropical brushes to the extra tropical forests, 

 A genus of two species a^ b^ is represented far 

 away in the west by two races a^ b^, the Bristle 

 Birds (Sphenura). Between these two areas the 

 country has been altered and the connecting links 

 have disappeared. Map 51 to indicate colour pat- 

 tern shows the approximate living ground of a 

 Yellow Robin (m), a Red-capped Robin (n), and 

 a Brown Scrub Robin (o). 



Yellow Robins love the quiet of forest vegeta- 

 tion, Red-capped Robins the broad edge of the 

 mallee gum country, and the Brown Scrub Robins 

 within the mallee scrub. 



The Yellow Robin is an eopsaltria, meaning 

 psalm of dawn, and the lovely form of this jonquil 

 coloured bird, as it silently passes from tree to tree, 

 is most attractive.
