I BIRDS OF AUSTRALIA. 



straw by the threshers. As might naturally be expected, 

 the agriculturist is often annoyed by the destruction 

 certain species effect among his newly-sown and ripening 

 corn, particularly where the land has been recently cleared and 

 is adjacent to the forests. About sixty well-defined species 

 of this family are described in the present work. They appear 

 to constitute four great groups, each comprising several genera, 

 nearly the whole of which are peculiarly Australian. 



I shall follow the arrangement of these birds as it is in the 

 folio edition as nearly as possible, and insert in their proper 

 places those species which have been discovered since the 

 completion of that work. 



Genus CACATUA, VieUlot, 



Australia, the Molucca and Philippine Islands and New 

 Guinea are the great nurseries of the members of this genus. 

 They incubate in holes of trees or in rocks, and lay two 

 white eggs.

If we regard the White Cockatoo of Tasmania and that of 

 the adjacent continent as mere varieties of each other, this 

 species has a very extensive range.
