get back again.

No species of the genus Artamus seems to enjoy a wider range 
than A. h'ucoyuster, being found alike at Cape York, and in 
Victoria and South Australia. It is generally found in the 
vicinity of watercourses, relining the deserted nestof Grallinapicata 
wherein to deposit its eggs. Only on one occasion have I heard 
of this bird building a nest for itself, and that was found by 
Mr. K. H. Bennett at Ivanhoe ; it was a loosely built structure 
of dried grasses placed in the horizontal fork of a small tree over 
hanging water. Eggs three in number for a sitting, of a dull 
white, spotted and blotched with faint markings of yellowish- 
brown, reddish-brown and obsolete markings of bluish-grey, the 
latter appearing as if beneath the surface of the shell ; these 
markings usually assume the form of a zone at the larger end. 
Dimensions of a set of three taken by Mr. Bennett on the 18th of 
October, 1885 are as follows, length (A) 0'9 x 063 inch ; (B) 
0-95 x 0-63 inch; (C) 0'9 x 0-62 inch. 
October and the two following months constitute the breeding 
season of this species.
