“ Little or no preference seems to be shown in the selection of a 
site for the nest of this bird. It is a dome-shaped structure, having 
a small entrance in the side and composed of grasses and stringy 
bark &c., 1 ined with feathers, cotton-tree down, or opossum-fur. It 
is placed in atuf t of grass, or low bushy shrub,but just as often among 
the loose pieces of bark which having accumulated in the forks of 
the Eucalypti hide all except the entrance of the nest. A liolo 
morticed in the side of a post and the fork of a Ti-tree where 
rubbish has accumulated alike serve its purpose, the shape 
depending upon the position chosen. The nests resemble those 
of the Malurus cyaneus both in size and shape ; they are however, 
much more bulky, thicker, and have a great quantity of lining, 
which renders them much warmer and more comfortable. The eggs 
which may be taken from August to December, are four in number 
0-G to 0-7 inch in length by (W to 0-5 inch broad, having a delicate 
white ground colour, spotted, freckled, or dashed with markings 
of reddish-brown of various tints and a few of purplisli-lilac-brown, 
in most forming a zone at the larger end ; the eggs of the young 
breeding for the first or second time are white without any 
markings. This species has three broods during the season, and 
if the nest bo taken will frequently build another in the samo 
place.” (Ramsay, R.Z.S., 1866, p. 575.)
