84 BIRDS or AUSTRALIA. 



Genus CAhOPSlTT A, Lesson. 



Like Mchpsitfacus, there is only one species known of this 

 genus. It is strictly Australian, and will doubtless hereafter 

 be found to be universally distributed over that vast country ; 

 it is equally well adapted for the plains as the last-mentioned 

 species, and the two birds are frequently found associated.

The range of this beautiful species extends over the whole 

 of the southern portion of the country, and the bird being 

 strictly migratory it makes a simultaneous movement south- 

 ward to within one hundred miles of the coast in September, 

 arriving in the York district of Western Australia precisely 

 at the same time that it appears on the Liverpool Plains in 

 the eastern portion of the country. After breeding and rear- 

 ing a numerous progeny, the whole again retire northwards in 

 Pebruary and March, but to what degree of latitude towards 

 the tropics they wend their way I have not been able satis- 

 factorily to ascertain. It would appear to be more numerous 

 in the eastern division of Australia than in the western. 

 During the summer of 1839 it was breeding in all the apple- 

 tree i^Aiigopkorci) flats on the Upper Hunter, as well as on all 

 similar districts on the Peel, and other rivers which flow to the 

 north-west. I have seen the ground quite covered by them
