Australian Bittern.

Buy-den-etch, Aborigines of the lowlands of Western Australia. 
Tue Australian Bittern, although nowhere very abundant, is so generally diffused over the surface of the 
country wherever marshes and the sedgy banks of rivers occur, that there are few localities of this 
description in which its presence may not be detected: owing to the frequent occurrence of such districts 
in Van Diemen’s Land, it is perhaps more numerous in that island than elsewhere. A fine specimen, which 
had been captured on the Torrens, was sent to me during my stay in Adelaide by Mr. Dark, the Surveyor ; 
I killed another myself on the Ist of July 1839, above Gleeson’s Station, while journeying towards the 
Murray, and I subsequently procured others at Illawarra and in Van Diemen’s Land: Captain Sturt 
mentions that he found it abundant in the marshes of the interior, in the neighbourhood of the river Mac- 
quarrie, and Mr. Gilbert procured it in Western Australia. 
In its actions, habits, manners and mode of flight it so closely resembles the Botaurus stellaris of Europe, 
as to render a description of them entirely unnecessary ; like that bird also it feeds on fish, frogs, newts, 
aquatic animals of all kinds, and insects, and has a capacious and membranous stomach. 
The sexes are alike in plumage, but the female is smaller than the male. 
Head and back of the neck purplish brown ; back and scapularies dark purplish brown ; wings buff, con- 
spicuously and largely freckled with brown; ear-coverts tawny 5 throat and all the under surface deep 
tawny buff, with irregular markings of deep brown down the centre, giving the whole a mottled appearance ; 
the brown colour however prevails on the lower part of the throat ; bill yellowish olive in some, greenish 
horn-colour in others; space round the eyes and the legs beautiful pale green ; irides in some yellow, lilac- 
red in others. 
The figures are about two-thirds of the natural size.
