The nest of this species is a scanty structure of rootlets or twigs, 
about four inches across, and usually placed on a horizontal branch 
of some tree or sapling — a favourite place being near the summit 
of a Casuarina about twelve or fifteen feet from the ground. 
The eggs are three in number for a sitting, of an olive ground 
colour, spotted and blotched with dark umber and brown markings, 
which form a zone on the larger end ; in a few instances they are 
heavily blotched with sepia. A set taken at Dobroyde in 1864, 
measure as follows: — (A) 0'92 x 07 inch, (unusually large and 
■heavily blotched); (B) 0'8f> x 067 inch; (C) 087 x 068 inch. 
The breeding season commences at the latter end of August, 
and continues to the middle of December.

Mr. K. H. Bennett found this bird breeding in the neighbourhood 
of Ivanhoe, New South Wales. A pair last year took possession 
of a deserted nest, of Cracticus niyrogularis, and constructed their 
nest on the old foundation, lining it with roots, strips of fine bark, 
and grasses ; inside measurement three inches across, and one and 
five-eighths of a inch in depth. The eggs are three in number for 
a sitting, and are not unlike large and well-marked specimens of 
those of Artamns sordidus, the ground colour being of a pale 
yellowish-buff tint; in one instance (c) spots of blackish-brown
