Mathews, Birds of Australia, Vol. X., p. 186, pt. Hi., pi. 469, Jan. 30th, 1923. 
Considered by Dr. A. M. Morgan as a sub-species of D. textilis, when he des¬ 
cribed the nest and eggs in the South Australian Ornithologist, Vol. VII., pt. 5, 
p. 159, Jan. 1st, 1924. He also corrects the locality from Cariewerels to 
Cariewerloo, a station on Myall Creek, twenty-two miles west of Port Augusta 
in the Gawler Ranges, South Australia. 
Nest. Situated 9 inches from the ground in a saltbush, well away from the scrub. The shape 
was an open cup, with no sign of a hood or other covering. The base was of very fine 
dead twigs of saltbush, on which the nest proper was built of very fine, dried, old grasses 
of a grey colour, matching well with the stems of saltbush, and scantily lined with rabbit 
fur. It was well concealed by an overhanging branch of the bush. Measurements: 
height overall 3| inches ; cavity, diameter 21 inches ; depth 14 inches. 
Eggs. Clutch three. Short ovals in shape, surface smooth with a slight lustre. The ground-colour 
of two of the eggs is a pale reddish-brown thickly covered with spots and splashes of bright 
red. The third egg has a white ground-colour, with markings of the same shape and colour 
as the other two. In all, the spots are more thickly distributed at the larger end. Measure¬ 
ments : 22-23 by 16-17 mm. 
Breeding-season. August (September). Collected on the 30th of August, 1923, near Wertigo 
Dam, about 50 miles S.S.W. of Port Augusta.
