104 THE USEFUL BIRDS 



The note of the bird is terminated by a smack as if made 

 with a whip, resembling somewhat, but much inferior to, the 

 crack of the " Whip-bird " (Psophodes). 



Although a winter resident, it is nomadic, passing from 

 place to place with its young, which do not mature for at 

 least two years. 



A similar species, occupying the fringes of the Mallee 

 country, is Gilbert's Thickhead, P. cjilherti, Gld. It has a 

 rusty-red throat and sandy-buff under wing coverts. 



A further plain-coloured species is found in the moist and 

 heavily -timbered lands of the east — i.e., P. olivacea, V. and H. 

 It has a whitish throat, freckled with brownish, dull fawn 

 below and olive on the upper surface. 



Nest. — Almost identical with that of the preceding species. 



Eggs. — Basal colour, after the nature of olive ; a zone of 

 spots of a similar shade (stronger) round the broad end. 

 Three to a sitting. Length, 1 inch ; breadth, 0.8 inch.
